STEAM AIR PREHEATER FOR A STEAM BOILER

1974-9-17 · As with low-pressure feedwater heater 38, a plurality of heat exchangers may comprise high-pressure feedwater heater 41. Finally, the flow enters boiler 20 to complete the cycle. Boiler feed pump 40 is driven by boiler feed pump turbine 50. In turn, boiler feed pump turbine 50 is powered by exhaust steam tapped from low-pressure turbine 27.

Steam and high temperature hot water boilers - Carbon

Steam and high temperature hot water (HTHW) boilers are commonly used in industrial feedwater may enter the boiler directly, or via a buffer tank. The temperature that this water is heated to will depend on whether the boiler output is steam or hot water. High temperature hot water boilers produce hot water at temperatures of over

Feedwater Heaters? - Trains Magazine - Trains News

A similar "blow down" occurs in internal combustion exhaust valve opening. Using a check valve, the feedwater heater can receive exhaust steam under pressure that is elevated above the atmospheric boiling point of water. This mean that in theory, a feedwater heater could preheat the incoming water to above 212 F of the atmospheric boiling point.

Elesco Exhaust Steam Injector: How did it work?

2007-1-12 · The exhaust steam, or live steam is then used to inject the water into the boiler. The water also passes through the smoke box before being injected into the boiler. Elesco claimed that at full exhaust steam the injector would place water into the boiler well over the boiling point.

Boiler | Engaged in Thermodynamics

Boiler feedwater often contains dissolved oxygen, which comes from air leakages inside the condensers and pumps. The deaerator mechanically removes the oxygen by passing steam through the feedwater heater. The economizer is the last component of the feedwater system.

2018-2-22 · turbine exhaust. Its feedwater is the chemically treated, high-purity water used to drive the steam turbine. The spent low-pressure steam from the steam turbines is passed thorough a condenser to recover the water as condensate. The condensate is collected in a hot well, and then pumped back into the steam generator. Heating The Feedwater That

Feedwater de-aeration | The steam turbine

Steam, typically bled either from the main turbine or boiler feed pump turbine, or taken from the feed pump turbine exhaust, is supplied for heating and de-aerating the ingoing feed-water. Feedwater, de-aerated to a boiler quality standard of typically 5 ^g (of oxygen) per kg (of water), i.e., five parts per billion.

Exhaust Steam Injectors vs. Elesco / Worthington feed

Allen Hazen wrote: The exhaust steam injector was-- assorted sources say-- called the "poor man's feedwater heater." This suggests that it was at least perceived as not being as effective as a "real" feedwater heater. And maybe that it was cheaper (at least in first cost: if it wasn't as good, the savings on purchase price would eventually have been eaten up by higher fuel bills, but as we

In a steam engine, a device to heat the feedwater up before it's fed into the boiler.The reason for doing this is that low-pressure exhaust steam, which can do little further work in expansion, is still fairly hot.This thermal energy would otherwise go to waste, so why not use it to heat the water going into the boiler up some? That way, less energy must be expended warming it up once it's in

Hancock Turbo Feedwater Heater Info

2015-2-27 · The Hancock feedwater heater was a little complex, but it was designed to switch automatically between exhaust steam from the cylinders and live steam for heating the feedwater. The pump could then be run continuously to match demand. The exhaust steam from the turbine was fed to the condenser to heat the feedwater.

Worthington Feedwater Heaters were of the direct type. The only disadvantage of a feedwater heater is that by warming the feedwater, it makes it impossible to use an injector to get that water into the boiler. Injectors require the feedwater to be cold in order to work.
