KSPC Achieves Another Major Milestone:THE STEAM DRUM LIFTING OF BOILER UNIT NO. 1

epco SPC Power Corporation completed another major project milestone

with the successful lifting of the steam drum of Boiler Unit No. 1 last May 29,

2009. Top management officials of KSPC, Doosan Heavy Industries and its

sub-contractors attended the ceremony held at the construction site.

Before the drum lifting was performed, several preparations were done to make

sure that the activity can proceed smoothly. First, the steel structure was

completed and checked for its structural stability. This is one of the essential

preparations to ensure that the steam drum is properly supported.

econd, the steam drum fabrication was completed on time as earlierscheduled. Third, the steam drum underwent shop inspection tests to make

sure that the drum is of reliable design and construction, and that this could

withstand pressure during operations.

Fourth, the steam drums packaging, transportation, handling and storage

were carefully done to guarantee that there will be no damage to the parts.

Fifth, the equipment used for the lifting was tested to make sure that this is

capable of supporting the drum up to the specified height.

After lifting the drum, pressure parts installation followed. These pressure

parts included water and steam headers and furnace water walls, among

others.

Coal Silo Shell Lifting of Boiler Unit No. 1

fter the steam drum lifting, the coal silo shell lifting of Boiler Unit No. 1

followed last June 5, 2009.

The coal silo is one of components of the fuel feeding system. It provides

temporary storage of crushed coal for continuous operation. The coal silo is

composed of the top frame, shell, middle shell, cone and chute.

Of these components, the coal shell is the only part fabricated at the

construction site. The rest were fabricated at the contractors shops.

Meanwhile, the two coal silo shells were lifted and installed in the boiler

structure and then connected to the silo cone.

Before the shells were lifted, the shell plate dimensions, diameter, welded

connection and painting quality, among other parameters were inspected to

make sure that the specification was properly followed.

Coal Silo Shell Lifting (cont.)

Several preparations were also made before the coal silo shell lifting was

conducted. The cone-chute-middle shell assembly was lifted first since it islocated below the shell. The top frame was also installed above the shell as

part of the fabrication plan.

Lifting the shell was not easy because the winds may cause the shell to

abruptly swing and trigger the collision of the steel structure and the shell. If

this happens, the shell and the steel structure may be damaged.

The other works related to the fuel handling system are now proceeding as

scheduled.

Shop Test for Steam Turbine

he steam turbine is one of the most important equipment in the operation

of the Cebu Power Plant. To make sure that all of its major parts will perform

to its designed working condition, it is inspected and tested using the following

methods: hydraulic pressure test, assembly inspection, over speed & dynamic

balancing test, function test for actuators, ultrasonic inspection of generator

rotor, and seat contact check for valves, among others.

The inspection and test of Cebu Power Plants steam turbine was performed in

Japan where it is manufactured. This was done in the presence of the supplier,

representatives of Doosan and KSPC in accordance with the approved Shop

Inspection Test Plan and EPC Contract.

Prior to the activities, the Shop Test Procedures were submitted for KSPCs

approval. This started last February 25, 2009 while the succeeding tests were

done after each test had been carried out and had satisfactorily passed the

criteria.

Successful Completion of theChimney Concrete Shell

or about a month of round-the-clock

construction, the chimney concrete shell

was successfully completed. The

construction of the chimney shell using

the modern slip forming technology

started on May 4, 2009 and was finished

on June 9, 2009 with the combined effort

of a team of two dozen Korean and Filipino

men led by a Hungarian. Blessed with a

good weather, works on the reinforced

concrete shell proceeded smoothly without

any interruption.

After the successful erection of the reinforced concrete shell, the final works ofthe main structure of the chimney will follow. This will include the

construction of its duct opening, the inner lining, stairs and platforms, among

others. Surely, the 110-meter high chimney will permanently change the

skyline of Naga and will standout as the landmark of KSPCs Cebu Power Plant.
