What is the function of economizer in boiler?

A common application of economizers in steam power plants 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 firing rates needed for the rated boiler

What Is a Feedwater Heater? (with picture)

2019-10-10 · A feedwater heater is a component of steam powered turbine installations and steam locomotives used to preheat the water in the primary boiler system. These components help to improve the overall thermal efficiency of the boiler and also protect against thermal shock damage. There are two types of feedwater heater, open and closed, both of which use exhaust steam from the turbine or

feedwater heater - Everything2.c

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

Boiler (power generation) - Wikiped

2019-10-2 · A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
