Boiler Stack Economizer. Flue gases from large boilers are typically 450 – 650°F. Stack Economizers recover some of this heat for pre-heating water. The water is most often used for boiler make-up water or some other need that coincides with boiler operation.
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.

Condensing Economizers – The cost-efficient way to convert water vapor to recaptured heat. Using feedwater-cooled finned tubing, our condensing economizer cools exhaust gases below their dew point, releasing latent heat bound up in the vapor. The amount of recaptured heat is considerable — about 1,000 Btu per pound of condensate. The CO2 reduction is also significant: one cubic foot for each

Combustion. The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Nuclear fission is also used as a heat source for generating steam. Heat recovery steam generators (HRSGs) use the heat rejected from other processes such as gas turbines .
Some boilers are designed with economizers built in, while in other cases, an economizer can be fitted on after the fact. Boilers operate by heating water to make steam, and using that steam for heat or energy generation. For the most part, a boiler is fairly efficient, but there is some heat loss when the byproducts of combustion are vented.
