Being initiated in 1938, the production of turbines has been successfully continued by Ural Turbine Works CJSC which was established in 2004. Having inherited trademark “TMW” from its forerunner Turbomotor Works OJSC, the Ural Turbine Works enterprise has also adopted the authority of one of the leading Russian machine-building companies designing and producing power equipment. Being a part of the RENOVA Group, the enter-prise is currently specialising in producing cogeneration steam turbines, gas turbines, and gas-compressor units for transporting natural gas.

In the Ural region it has been produced more than a half (in terms of capacity) of cogeneration turbine plants operating in Russia and in 14 neighbouring countries, former Soviet repub-lics. The turbines marked as “TMW” are installed in the Eastern

European countries, Italy, Egypt, Mongolia, China, Korea, India, and Japan.

The Ural gas-compressor units are used in world-famous gas pipelines, including the Urengoy-Pomary-Uzhgorod pipeline sup-plying gas to the Western European countries.

Having a wide range of machines and many years of experi-ence in designing turbines, UTW CJSC meets the needs of differ-ent customers. In spite of the variety of produced models, the UTW specialists use only well-tried solutions, structurally unifi ed units and parts, which ensures suffi cient serial production, increases reliability and serviceability of turbines, and facilitates their repair.

The enterprise’s quality management system is in compliance with ISO 9001:2000, which was approved by the British Standards Institute (BSI).

Engineering The enterprise’s technical services include the special design

bureau, technological, metallurgical, scientifi c, and research depart-ments. The services develop and adopt new types of turbines mod-ernising the scientifi c and technological heritage of the enterprise.

The enterprise’s engineering services represent a number of re-search laboratories united into the department of experimental tech-nology and control of materials.

The staff of the technical services consists mainly of graduates of

the famous Ural turbine-building-school, department “Turbines and Diesel Engines” of the Ural Federal University.

When designing steam turbines, the UTW specialists use a modu-lar concept of design. This approach allows using well-tried and reli-able units of steam turbines in various models as well as speeding up the process of designing.

The enterprise is equipped with benches for testing steam tur-bines, which improves the quality of turbines, makes them more ef-fi cient and reliable.

ProductionUral Turbine Works CJSC is basically an enterprise with a

complete industrial cycle. Its production includes forging, thermal, welding, tool-making, and mechanical assembly production and consists of 4 divisions:

Turbine productionBlade productionTest bench of balancing of rotorsBlank production

Turbine production The product range of the steam turbine production (STP) in-

cludes parts of steam turbines, adjustment units, spare parts for power equipment.

The steam turbine production is divided into the following parts: preliminary stator, fi nal stator, iron rings, and diaphragms, rotor and gear-cutting, inserts, auxiliary.

The steam turbine production has assembly and test bench-es for steam turbines ПТ-90/120-130/10-1, Т-100/120-130,Т-140/165-130/15-2, Т-60/65-130-2, Т-185/210-130, Т-250/300-240, and adjustment units. The site is equipped with universal machines for carrying out adjusting activities in the process of assembly and with cranes which allow transporting units of up to 125 tons.

The main equipment of the steam turbine production includes the following: turning machines (diameter of processed parts – up to 2 m, length – up to 10 m), turning and boring machines (di-ameter of processed parts – up to 12.5 m, length – up to 5 m), milling and boring machines Skoda with the height of processing of up to 5 m, rotor and milling machines, and gear treating machines.

The steam turbine production produces adjustment units for steam and gas turbines: servomotors (HP, MP, and LP parts), pumping groups, valves of the disengaging clutch, different drives, and adjustment units.

Blade production Ural Turbine Works CJSC produces blades of various sizes:

from 50 mm to 1000 mm, both for steam turbines of its own pro-duction and for steam turbines of other manufacturers.

The principal technological equipment includes specialised machines of Swiss companies Lichty, Schaublin, Koher, Chiron having high processing level and being approved by a number of leading manufacturers of power equipment and turbine blades.

The modernisation of the blade complex started in 2006. Over the years the site designed for high-speed processing of blades was created and expanded. The introduction of modern equipment in the blade production considerably speeds up the manufacture of new blades, decreases the duration and labour intensiveness of processing, the amount of adjusting and manual operations, and makes the products more qualitative.

Test bench of balancing of rotorsThe test bench of balancing of rotors (TBBR) is used for activi-

ties on blading, assembly, and balancing of rotors of steam and gas turbines.

The main processes include the following:• Testing of moment weight scales of working blades;• Blading of mounted disks and solid-forged parts of rotors of

steam turbines as well as blading of iron rings, rotors of the compres-sor and rotors of gas turbines;

• Assembly of rotors (attachment of disks and bushings, instal-lation of half-couplings, adjustment of the high pressure rotor to the pump rotor and adjustment of the disengaging clutch);

• Fitting and mechanical activities, including turning of bladed rotors;• Static balancing of working wheels, dynamic vacuum balancing

of rotors of steam and gas turbines at balancing bench ДИ-10 (max of a balanced part – 5,000 mm, max length between supports – 10,000 mm, max weight of a part – 80 tons, max number of rotations – 4,500 rpm, with a step-up reducer – 9,000 rpm);

• Repair of rotors, including disassembly of a rotor, re-blading, fault detection, blading, assembly, and balancing.

The balancing of rotors of other manufactures weighing up to 80 tons and with maximum speed of rotation in the vacuum chamber of 18,000 rpm is possible.

Blank production The blank production includes welding, forging, and thermal ac-

tivities.The welding production specifi es metal cutting and welding of

metallic structures for turbines (condensers, heaters, associated and accessory equipment).

In most cases the production of welding constructions is a process completely connected with UTW CJSC. The process of production begins from preparation of metal and severing of fl ats and bars and ends in tests and separate operations.

The forging and thermal activities include forged pieces for steam and gas turbines both at mechanical sites of UTW CJSC and for third-party customers as well as heat treatment of workpieces and parts after preliminary machining and welding.

THE FAMILY OF TURBINES Т-250/300-240 FOR SUPERCRITICAL STEAM PARAMETERS

The family includes the base turbine Т-255/305-240-5 and four its modifi cations: Т-285/335-240*, Т-265/305-240-С, Т-250/305-240-Дand Т-250/305-240-ДБ. These turbines are intended for use at power plants which supply heat and hot water to metropolises and cities. They are highly effi cient under heat-extraction conditions and, at the same time, rather economically operate at purely condensing (sum-mer) conditions.

The turbine type Т-265/305-240-С is designed for power plants with a reduced (0.3) extraction factor (α ТЕР) (cf. 0.5-0.6 of the base model), that is appropriate for power plants located within city boundaries. For this purpose, the fl ow rate of the heating-system wa-ter through the heating system heaters (HSHs) is increased and the extraction pressure is slightly lowered. The maximum heating of the heating-system water is limited to 106 °C.

The turbines type Т-250/305-240-Д and Т-250/305-240-ДБ are designed for remote power plants located 30-35 km away from a town. The heating-system water is heated in three stages to tempera-ture of 150 °С (in case of the base model, in two stages to 117 °С).The turbine with “Д” index is installed in circuits with a deaerator of 7 kgf/cm2, while the turbine indexed “ДБ” is intended for deaerator-free circuits where the direct-contact low-pressure heater (LPH) No. 2 acts as the deaerator.

All turbines of the family are designed as single-shaft four-cylinder units. They vary in the design of the second intermediate pressure

cylinder (IPC-2). In the case of one- and two-stage heating of the heating-system water, the pressure of the steam delivered to the user is adjusted with regulating diaphragms installed in each fl ow of the LPC. If three-stage heating is used, the adjustment is realized with a regulating valve mounted in the third heating stage of the extraction pipeline.

For basic characteristics of the turbines comprising the familyТ-250/300-240 see Table 2.

* Design temperature of live steam and intermediate superheating steam for the base turbine and three of its modifi cations is 540 ºС, whereas for turbine type Т-285/335-240 this temperature is 560 ºС.

THE FAMILY OF TURBINES Тп-185/220-130The family includes the base turbine Тп-185/220-130-2* and its

modifi ed version Тп-185/215-130-4. The turbines of this family are designed for power plants of large cities.

These turbines offer limited process steam extraction at pressure of 25-35, 12-18 and 8-12 kgf/cm2. On customer’s choice, either or any two of these extractions can be used as well as non-extraction opera-tion. The pressure of steam supplied to the user from these extrac-tions is maintained with regulating valves in the extraction pipelines.

Both turbines of this family have two-stage heating of the heating-system water. The extraction steam pressure is controlled with regu-lating diaphragms mounted in each fl ow of the LPC.

The turbines are single-shaft three-cylinder units with a unifi ed fl ow passage. The turbines indexed “2” and “4” are equipped with exhaust rotor blades 830 mm and 660 mm long and their design tem-perature of cooling water is 20 °C and 27 °C respectively.

THE FAMILY OF TURBINES ПТ-140/165-130/15The family consists of the base turbine ПТ-140/165-130/15-2М* and

three its modifi ed versions: ПТ-140/165-130/15-3М, ПТ-150/165-130/9-4 and ПТ-140/165-130/15-5. The turbines of this family are installed at big industrial heating power stations working under large process steam extraction load. The base turbine is outfi tted with exhaust blades 830 mm long and is designed for the cooling water tempera-ture of 20 °С. The turbines indexed “3”, “4” and “5” have exhaust rotor blades 660 mm long and their design cooling water tempera-ture is 27 °С. The turbine indexed “4” differs from the other two turbines in the nominal pressure of the process steam extraction, which equals 9 kgf/cm2 instead of 15 kgf/cm2. Therefore this turbine has a different number of HPC and LPC stages. All the turbines are provided with two heating steam extractions. A regulating dia-phragm is installed downstream of each extraction, except for the turbine indexed “5”. The turbine indexed “5” is fi tted with a single regulating diagram, which is installed downstream of the lower heat-ing steam extraction. In the case of one- or two-stage heating of the heating-system water the extraction pressure is adjusted using one regulating diaphragm of the lower extraction. If extraction serves other auxiliary power, the extraction pressures can be separately controlled by both regulating diaphragms. The pressure of the main process steam extraction from the HPC exhaust is maintained with

regulating valves installed at the LPC inlet. An additional process steam extraction with the pressure of 25-35 kgf/cm2 is provided. The pressure is maintained downstream of the regulating valve in the extraction line. The turbines are made as single-shaft two-cylinder units.

Basic characteristics of the turbines type ПТ-140/165-130/15 are summarized in Table 4

THE FAMILY OF TURBINES Т-110/120-130The family consists of the base turbine Т-110/120-130-5М* and

its four modifi ed versions: Т-116/125-130-7М, Т-120/130-130-8М, Т-120/130-130-12,8 and ТР-110-130 (back-pressure). The turbines of this family are intended for newly constructed or extended power stations serving large or medium-size cities. Considering that the thermal load of these power stations is often uncertain or is not provided during initial years of operation, the T-100 turbine has been designed as a partially uni-versal one: it operates rather effi ciently both under various thermal loads and at straight-condensing conditions. The turbine can run at thermal schedule regimes (with back-pressure) when the built-in condenser banks are cooled with makeup or heating system water. It has a rather devel-oped low-potential section, a condenser group with an optimal fl ow rate of cooling water, and a developed regenerative system. Many advanced ap-proaches worked out for extraction turbines have been realized in the tur-bine. It has been constantly improved and has passed fi ve modernizations (index “5”). Thanks to the above merits, the turbines of T-110/120-130family have been produced on the largest scale ever known: today these turbines run to over two hundreds in number.

The modifi ed versions differ from the base turbine in the fl ow rate of live steam and, correspondingly, in nominal power and thermal load. Besides, the turbine TP-110-130 has neither LPC nor condens-er group. In the currently produced turbines of the family, the dou-ble-row regulating stage has been replaced by the single-row stage. Design of the HP cylinder has been changed as well. Turbines with the single-row regulating stage bear the index “O” at the end of their designation. The single-row regulating stage enhances effi ciency of the turbines in operating conditions, which are close to design ones, i.e. when the turbines operate in base-load conditions. The same so-lution can be applicable to turbines Тп-115. All the four turbines of the family offer two-stage heating of the heating-system water. The

extraction steam pressure of the fi rst three turbines is maintained with regulating diaphragms installed in each fl ow of the LPC, while in the fourth turbine the pressure is controlled by moving regulating valves of the high-pressure section.

The turbines are made as single-shaft three-cylinder units, except for ТР-110-130 that is made as a single-shaft two-cylinder unit.

Basic characteristics of the turbines typeТ-110/120-130 are listed in Table 6.

THE FAMILY OF TURBINES Тп-115/125-130This family is intended for technical re-equipment of power sta-

tions through their extension or replacement of obsolete turbines rated at 25, 50 and 100 MW. The turbines can be installed at newly constructed power stations as well. The family of turbinesТп-115/125-130* has been developed on the basis of the turbineТ-110/120-130-5. However, taking into account that the turbines of this family are installed in turbine hall of existing power sta-tions, they are framed in two cylinders and have a simplified re-generative system (one HPH and one LPH are removed), one condenser instead of two condensers, and lower flow rate of cool-ing water. Since boiler equipment is usually replaced later than turbines, the turbines of this family can continuously operate (if so stated in the order) on live steam with p0= 90 kgf/cm2 (8.8 MPa) and t0= 535 °C with subsequent change-over to live steam with p0= 130 kgf/cm2 (12.8 MPa) and t0= 555 °C when required.

The family comprises three models: Тп-115/125-130-1М, Тп-115/125-130-2М, and Тп-115/125-130-3. In addition to the main heating steam extractions, all the three turbines provide limited auxiliary steam extraction (indexed with small Russian letter “п”).

If the turbines type Тп-115/120-130 are installed at operating power stations, thermal loads of the turbine are generally well known and therefore the most suitable modification (model) of the turbine can be selected for particular power station conditions.

* The turbine was designed as a part of turbine group which includes the family ПТ-90/120-130/10

2For example, the turbine indexed “1” having the last stage blades 550 mm long is appropriate in the case of large thermal loads (small steam flow rates in the condenser), which are preserved, to a certain extent, in summer period. Such usage is appropriate because this turbine is most efficient under large thermal loads (low losses at the blades of the low-pressure section): it requires only 8000 m3/h cooling water and can operate under the thermal regime with the built-in condenser bank being cooled either with make-up or heating-system water. However, at low thermal load and, all the more so, under straight-condensing conditions, this turbine is inferior to the other turbines in efficiency. Note also that the condensing power of the turbine is limited to 115 MW.

The turbine indexed “2” has the last stage blades 660 mmlong. It is less efficient than the turbine indexed “1” under full ther-mal load but is more profitable under small thermal loads and un-der straight-condensing conditions. The condensing power of the turbine “2” is 125 MW. The cooling water flow rate is 13,500 m3/h. When working under the thermal regime, only make-up water can be passed through the built-in bank (system water is excluded).

The design temperature of cooling water of the turbines “1” and “2” is 27 °C.

The turbine indexed “3” is equipped with last stage blades 940 mm long. The turbine is fit for continuous operation under straight condensing conditions. Here its efficiency approximates

efficiency of turbines of T-110-130 family. The design temperature of cooling water is 20 °C.

Basic characteristics of the turbines Тп-115/125-130 group are given in Table 7 and Table 8 for the steam pressure p0= 130 kgf/cm2

(12.8 MPa) and p0= 90 kgf/cm2 (8.8 MPa) respectively. See also the note for the turbine Т-120/130-12,8.

THE FAMILY OF TURBINES ПТ-90/120-130/10The family includes three turbines: ПТ-90/120-130/10-1*,

ПТ-90/125-130/10-2 and ПТР-90/100-130/10. Like other turbines of the group, the turbines of this family are based on the turbine Т-110/120-130-5. They can be used for technical re-equipment of existing power stations or can be installed at newly constructed plants. The turbines have a simplifi ed regenerative system. The tur-bines ПТ-90/120-130/10-1 and ПТ-90/125-130/10-2 offer a low fl ow rate of cooling water and can run, if so stated in the order, on live steam with p0= 90 kgf/cm2 (8.8 MPa) and t0= 535 °C.

The turbines indexed “1” and “2” are equipped with last stage blades 550 mm and 660 mm long respectively. Therefore, when deciding which model to order, consider the information presented in Section 6 for the turbines Tп-115/125-130 indexed “1” and “2”.

The turbine ПТР-90/100-130/10 has no condensing plant (con-denser, circulating and condensate pumps) and does not require circulating water supply. As a result, the thermal circuit of the power plant is simplifi ed, the cost is reduced, and the labor input to the manufacture and installation of the turbine plant is lowered. How-ever, the turbine can operate continuously only if an all-year-round thermal (heating) load is provided.

Basic characteristics of the turbines ПТ-90/120-130/10 family are summarized in Table 9 and Table 10 for operation on steam withp0= 130 kgf/cm2 (12.8 MPa) and p0= 90 kgf/cm2 (8.8 MPa) respec-tively. See also the note for the turbine Т-120/130-12,8.

STEAM TURBINES FOR COMBINED-CYCLE POWER PLANTCurrently, issues concerning development of modern equipment

operating as part of combined-cycle power plants (CCPPs) are be-coming more and more vital. Providing succession of UTW steam turbine manufacture design decisions, the company has worked over CCPP variants with capacity 95 – 450 MW. A classic CCPP includes one or two gas turbines, one or two waste-heat boilers and one steam turbine with the appropriate number of generators.

For a CCPP with capacity of 90 … 100 MW, UTW offers the sin-gle-shaft steam extraction turbine Т-35/47-7,4 (see the Table below). For a CCCP with capacity of 115 MW, steam turbine Т-40/50-8,8 is offered.

For two-circuit CCPPs with capacity of 170...230 MW, we offer steam extraction turbines Т-53/67-8,0 and Т-63/76-8,8 (see the Table below). On the basis of this turbine, the plant can also manufacture condensing turbines with capacity of 60…70 MW.

For three-circuit CCPPs with resuperheating function and capacity of 400…450 MW, UTW offers steam extraction turbine Т-113/145-2,4(see the Table below), which, with its design preserved, but depend-ing on different steam parameters, may also bear designations from Т-100/130-12,0 to Т-125/150-12,6. On the basis of this turbine, the

plant can also manufacture condensing turbines with capacity of 130…150 MW.

Basic characteristics of the turbines for CCPPs are provided in Table 12.

EXTRACTION STEAM TURBINES OPERATING ON LIVE STEAM WITH р0= 90 KGF/CM2 (8.8 MPA), t0= 535 °С

The extraction steam turbines designed to work on live steam with pressure of 130 kgf/cm2 (12.8 MPa) and temperature of 555 °С are capable of operating continuously on live steam with p0= 90 kgf/cm2

(8.8 MPa) and t0= 535 °С without any modifi cations made in the tur-bine design. This is important for power plants where the turbine hall is reequipped without replacement of the boiler equipment. In this case the turbine parameters (live steam fl ow rate, electric power, process steam fl ow rate, and heating load) lower correspondingly.

For example, when the base turbine type ПТ-140/165-130/15 works on live steam with pressure of 90 kgf/cm2 (8.8 MPa), it turns into the turbine ПТ-100/130-90/13 after a slight modifi cation.

To improve characteristics of the turbine operating on low-param-eter steam, certain design changes can be made. If necessary, the turbine can be switched back to operation on live steam with pressure of 130 kgf/cm2 (12.8 MPa). This option is realized in the family of tur-bines Tn-115/125-130 and ПТ-90/120-130/10.

CONDENSING STEAM TURBINESIf minor changes are introduced in the design of the turbines manufac-

tured at Ural Turbine Works, they can serve as a basis for development of condensing steam turbines with the following parameters:

1) live steam at 90 kgf/cm2 (8.8 MPa) and 535 °C:- rotational speed of 3,000 rpm and power equal to 50-150 MW;- rotational speed of 3,600 rpm and power equal to 50-60 MW.

2) live steam at 130 kgf/cm2 (12.8 MPa) and 555 °C:- rotational speed of 3,000 rpm and power equal to 50-220 MW;- rotational speed of 3,600 rpm and power equal to 50-60 MW.

3) for CCPP (see Table 12)

EXHAUST STEAM TURBINES Ural Turbine Works offers, to its customers, exhaust steam tur-

bines. They work from heating collectors and process steam extrac-tion of turbines ПР, ПТР, Р, ПТ, П and T when they are not loaded to its purpose. Process steam extraction for heating can be organ-ized from the turbines worked from the collector. Incomplete load-ing of heating extraction can exist in spring-autumn period; during summer, the loading can be zero. Absence of steam consumption from exhaust of the turbine type “P” leads to full stop. Decrease of process steam extraction from turbine types “П”, “Т” and “P” reduces turbo-generator set power. In these cases exhaust-steam turbines installation allows a complete loading of the turbines and provides their work at an effi cient design condition. Besides, electric power of power plants increases due to new turbines at comparatively low capital inputs, because installation of new power-generating boilers is not necessary.

Main technical data of exhaust steam turbines are summarized in Table 14.
