Steam is used throughout industry for process and space heating. Within the process industries, steam is used in oil refineries; pulp and paper mills; chemical production, such as ethylene and ammonia; food and grain processing; and textiles.

Refineries and chemical plants use steam tracing to reduce pumping costs of viscous material and prevent freezing of process piping. Steam is used for heat exchangers and reactors to assist or create process chemical or thermal reactions. Paper mills utilize major steam generation systems to generate power and dry paper products. Steam is widely used for district energy systems found in major municipalities and central plants of universities and hospitals.

To minimize piping cost, steam is generated and distributed at much higher pressures and temperatures than are required by the process load. Fisher® regulators are utilized in these applications to reduce the steam pressure to a usable level and to accurately maintain process fluid temperatures.

Steam applicationS

StEaM ValVES FoR HEat tRanSFERaPPlIcatIonS

Steam heat transfer is a primary application for Fisher® brand steam regulators. Steam heat is transferred to a process fluid through direct injection or non-contacting devices. Examples of direct injection heat transfer equipment are deaerator tanks, humidification devices, and autoclaves. Shell and tube heat exchangers, jacketed kettles, coils, and steam tracing are examples of non-contacting devices.

There are several methods of controlling the amount of steam required to heat a fluid. The purpose of these control methods is to deliver the proper amount of heat energy to create an energy balance across a heat transfer device and to deliver the heat energy as efficiently as possible. A heat transfer system is balanced when the process fluid’s temperature is maintained under all operating conditions. If too much heat energy flows into the system, the process fluid temperature will rise above its desired temperature. When too little heat energy flows into the system, the process fluid temperature will never reach its desired temperature.

Efficiency is achieved when the lowest possible steam pressure is used to transfer steam heat energy. This energy is called latent heat and is the heat required to turn 100% steam into 100% water. Steam’s latent heat increases when steam pressure is lowered. Since the energy content (BTU/lb) of the steam increases, less steam flow is required to achieve an energy balance. Lowering the steam flow reduces the demand on a boiler, which means it will burn less fuel.

There are consequences to be considered when selecting a steam delivery pressure. First, as steam pressure is lowered its temperature is reduced. Although the latent heat has increased, its energy potential or “muscle” required to deliver heat is reduced. Typically, a larger steam heat exchanger will be required to maintain the desired energy balance. Also, the warm-up time will be increased, which may have revenue impact on batch processes. Finally, the fluid mechanics of removing condensate must be considered. When steam loses all of its latent heat in a heat exchanger, the steam turns to water. This water is called condensate and must be removed from the heat exchanger and returned to the boiler. The condensate system must be designed

and installed based on the pressure and flow to the heat exchanger. Using lower pressures may require alternative methods to remove and return condensate to the boiler.

HEat tRanSFER contRol MEtHod

In maintaining an energy balance, a process fluid’s exit or outlet temperature is usually measured to adjust a valve’s position or travel. Several valve configurations are used to achieve the desired result.

Pressure Reducing Valves

Pressure reducing valves or PRV’s are the most common method for reducing steam pressure and controlling steam flow. They are common because they are the most cost-effective valve arrangement. PRV’s only sense and position themselves based on downstream steam pressure. They respond to process temperature changes through the condensation rate in a heat exchanger.

Steam applicationS

Preheating makes the oil easier to pump and atomize, while atomizing increases the surface area of the oil that is available for combustion.

Atomizing steam is fed into the atomizer at a higher pressure than the oil. Oil pressure may fluctuate due to pumping and combustion conditions so the steam pressure must follow proportionally. In order to do this, oil is tubed to the spring case of the valve to bias the spring setting of the valve. This ensures that proper differential pressure between the steam and the oil occurs before entering the atomizer.

Relief Valves

Fisher® brand steam relief valves are not ASME certified. They are used in applications where non-coded devices are acceptable.

Flash tanks

Flash tanks help improve steam system efficiency. They receive high pressure condensate. Condensate is then exposed to a low pressure steam source. When this occurs a certain percentage of condensate will vaporize or “flash” to steam at the lower pressure. This steam can be used on other low pressure steam heat transfer devices.

A relief valve is used to vent steam when flash steam exceeds the demand of the low pressure system. It is normally set at a lower pressure than the safety relief valve to prevent nuisance pops of the safety valve and build-up of pressure in the low pressure steam header.

accumulators

Accumulators are one of the most overlooked devices in today’s steam industry. Essentially, they are large high

than 10:1, valve trim erosion and noise can become a problem. Installing two valves in series helps reduce these problems. Although this is the most costly of self-powered valve installations, it is more economical when used in applications that operate 24 hours a day, year round.

differential Regulators

These regulators are used for fuel oil atomizing. As the cost of natural gas and oil fluctuate, many boilers have dual fire capability. They can switch fuels when required to insure the lowest cost fuel is burned. Most fuel oils require preheating and atomizing to insure complete and clean combustion. Oil is typically preheated from 120° to 140°F (49° to 60°C) and then atomized with steam or air.

Figure 2. Flash TankAvailable energy in high pressure condensate can be recovered by using flash tanks. The steam from the flash tank can supplement low pressure steam heating needs.

pressure flash tanks that protect boilers from operating under capacity. Most boilers are rated for maximum demand; however, they can not respond to instantaneous demands that often occur in the process industries. When the steam demand is instantaneous, cooler feedwater is pumped into the boiler and must be heated to boiling temperature. Since this process takes time, the boiler will temporarily operate under capacity. Problems associated with under capacity operation are carry over of wet steam, dissolved solids, and water slugs that occur with the shrink and swell of the water level in the boiler. A worst case scenario occurs when the boiler’s water level shrinks below the tube level, exposing tubes to combustion gases.

An accumulator can cushion the instantaneous demand spike by flashing high pressure steam into the main steam header while the boiler catches up to the

demand. A pilot operated backpressure relief valve is installed in the steam header to maintain header pressure, which keeps the boiler operating at a constant pressure and stabilizing water level in the boiler. Adverse effects of under capacity operation are avoided as long as there is an appropriate amount of water available for flashing during the demand spike.

When replacing an older boiler, it may be a good idea to save the shell if space permits. It can be filled with feedwater and used as an accumulator.

Regulator Tips

• When heating liquids, use an approach temperature around 30° to 50°F (17° to 37°C). • Install heat transfer compound in all thermowells. • To reduce noise and erosion, limit pressure drop ratios across the valve to 10:1. • Use the lowest possible steam pressure to increase efficiency. • Steam valves should be lapped annually to improve shutoff. • If scale and rust are found in regulator valves, inspect the boiler and review boiler operation because most non-condensibles originate from the boiler.

Steam productS

Introduction

The Type 92C self-powered control valve is a cost effective pressure reducing regulator used in steam service. This valve is available with a Type 6392 pilot or without a pilot for use as a pressure-loaded valve. The pilot-operated version uses inlet pressure as the operating medium; no separate air supply is required. The pressure-loaded version is used where remote adjustment of the valve pressure setting is required.

Introduction

The Type 92P is a pressure-loaded, diaphragm actuated, self-powered control valve that is rated for inlet pressures to 300 psig (20,7 bar) at 600°F (316°C). The Type 92P uses an external air signal to maintain the downstream pressure setting. This allows for pressure regulation without the use of a steam operated pilot. This valve is ideal for low purity steam applications and where frequent maintenance of steam operated pilots is an issue.

Steam productS

Introduction

The Type 92S self-powered control valve is piston actuated for high cycle steam service. This valve and pilot use lapped seating surfaces that have been proven to minimize seat leakage. The Types 6492H and 6492L pilots have bellows sealed stems to eliminate stem guide friction. This valve should be used with clear, dry, or superheated steam.

Introduction

The 95H Series regulators are compact, rugged, direct-operated, pressure reducing regulators. The units are available in 1/4 and 1/2 through 2-inch (DN 15 through 50) body sizes and are offered with several different end connection styles. They are designed to handle inlet pressures up to 600 psig (41,4 bar) and temperatures up to 650°F (343°C).

The Type 95HD differential pressure reducing regulator uses spring force to maintain a pressure differential between the spring case loading pressure and the regulator outlet pressure.

Steam productS

Introduction

The 95L Series regulators are compact, rugged, direct-operated, low-pressure regulators for outlet pressures of 2 to 30 psig (138 mbar to 2,1 bar). The units are available in 1/4 and 1/2 through 1-inch (DN 15 through 25) sizes and are offered in several different end connection styles. The Type 95L is designed to handle inlet pressures up to 300 psig (20,7 bar) and temperatures up to 450°F (232°C).

The Type 95LD low-pressure regulator uses spring force to maintain a pressure differential between the spring case loading pressure and regulator outlet pressure.

98H Series Backpressure/Relief Valves

151

Steam productS

Introduction

The Types 98H and 98HH are direct-operated, spring-loaded backpressure/relief valves. The 98H Series are used in a variety of steam backpressure/relief applications, such as power generation, heating and cooling systems, and process systems.

The Type 98HD uses additional loading pressure to maintain relief differential pressure settings. This backpressure/relief valve is used for differential control in steam applications, such as steam atomization of fuel gas for a boiler.


See Table 1

Steam productS

Introduction

The Type 98L is a direct-operated, spring-loaded relief valve/backpressure regulator. The Type 98L is used in a variety of steam backpressure/relief applications, such as power generation, heating and cooling systems, and process systems.

The Type 98LD uses loading pressure to maintain the differential relief pressure setting. This backpressure/relief valve is used for differential control in steam applications, such as steam atomization of fuel gas for a boiler.


See Table 1
