Economizer – Wikipedia

Economizers are commonly used as part of a heat recovery steam generator in a combined cycle power plant. In an HRSG, water passes through an economizer, then a boiler and then a superheater. The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler.

Economizer in Thermal Power Plant | Economizer – Listenlights

You can well understand form the discussion above that, cooling the flue gas below 250 o F and transferring that additional heat to the boiler feed water would have resulted in greater efficiency, but in a coal fired power plant, this should not be done, since coal as a fuel contains sulphur in a very large extent as impurity. And the flue gas

Boiler (Steam Generator) – Coal Fired Power Plant – Thermal

A boiler or Steam Generator (prime mover) is an integral device in a fossil fuel power plant used to produce steam by applying heat energy to water. A boiler incorporates a furnace in order to burn the fossil fuel (coal, gas, waste etc.) and generate heat which is transferred to water to make steam.

What is the function of economizer in steam power plant

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 firing rates needed for the rated boiler output.

Why Economizer and Air PreHeaters are Provided in Boilers

Boilers operate with around 86 to 90% efficiency depending upon the type of fuel and design adopted. A degrease of about 20 % of boiler efficiency is seen by not providing both economizer and air preheaters. If economizer alone is provided then the efficiency will be lower by 12 % when compared to that with economizer and air preheaters.
