Why is an economizer used in a boiler? - Quora

Jun 26, 20170183;32;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 output.

High-alloy Materials for Boiler Tubes

Chromium is the key element influencing the corrosion behaviour of steels. The sensitivity of the material to steam-side oxida- tion as well as fire-side corrosion is an important factor for use in the field of boilers. The use of high sulphur coal makes the fire-side corrosion resistance of even higher importance.
