A feedwater economizer reduces steam boiler fuel requirements by transferring the temperature of the generated steam. Generally, boiler efficiency can be increased by 1% for every 40°F reduction in flue gas temperature. By recovering waste heat, an economizer can often reduce fuel .

    Another way to look at the efficiency of both boiler types is this: The HRSG generates an additio lb/hr of steam with a fuel input of only million Btu/hr (subtract the fuel input at , lb/hr steam from the unfired case steam generation). The package boiler, on the other hand, requires 84 million MM Btu/hr ().

Except for natural gas, practically every fuel leaves a certain amount of deposit on the fireside of the tubes. This is called fouling, and it reduces heat transfer dramatically. Tests show that a soot layer just mm ( in.) thick reduces heat transfer by. The steam jacket practically considered as an efficient fuel economiser.

[Leather Bound]. A common application of economizers in steam power plant is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater.

This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the. 2) The Indirect Method:Where the efficiency is the difference between the losses and the energy input. The Direct Method Testing Description This is also known as ’input-output method’ due to the fact that it needs only the useful output (steam) and the heat input (i.e.

fuel) for evaluating the efficiency. This efficiency can be eval-File Size: KB. Colin French CEng, FlnstE, FBIMgt, in Plant Engineer's Reference Book (Second Edition), Introduction. Economizers for boilers have been available for nearly years, almost as long as boilers themselves.

For modern shell boilers, high efficiencies have made it increasingly difficult to justify the use of an economizer, the final decision being based in terms of payback period. † Steam is nontoxic, nonflammable, visible if it leaks externally, and inert to many (but not all) process fluids.

Most sites have a pipe network supplying steam at three or more pressure levels for different pro-cess uses. A typical steam system is illustrated inFigure Boiler feed water at high pressure isFile Size: 1MB.

The steam-generating facility, located in the boiler room, consists of boilers, feedwater systems, heat exchangers (e.g., economizers), boiler and system controls, fuel and gas handling equipment (e.g., fuel trains, stacks), and steam/water treatment equipment and piping (Figure 2).

This is based on a boiler efficiency of about 85% and lower heating value (LHV) of fuel at 18 Btu/lb (10 Kcal/kg). Turbine steam inlet pressure is a major parameter affecting turbine performance. To retain the design efficiency the steam inlet pressure should be maintained.

steam from the oil-fired straight watertube boilers. The Medea’s steam engine and boiler, although built six years later, are typical of the previous generation of steam plants, the two-cylindered compound double-expansion engine supplied with steam from a firetube boiler, File Size: 2MB.

The efficiency of an exhaust gas economiser can be improved by increased soot blowing frequency (once or twice a day while at sea). Generally a funnel temperature of to deg C when using fuel oil is considered optimum.

Location (relative to water and fuel). 3. Space available (each power plant has a certain area/unit energy produced). 4. Reliability: Steam turbine life is extremely long.

There are steam turbines that.Direct steam injection (DSI) heaters inject steam directly into the circulating water loop. For processes which return the jacket water below °F, they achieve % heat transfer by using both the sensible and the latent heat of the steam.

Above this temperature there is a minimal drop in efficiency.
