What is the purpose of an economizer in a thermal power plant?
What is the purpose of an economizer in a thermal power plant?
- To preheat the cold feedwater using hot waste gases from the fuel reactions within a boiler (correct)
- To cool the used steam that has passed through the steam turbine
- To inject pre-heated air with coal in the boiler to improve coal combustion
- To convert chemical energy into heat energy

What does an economizer do in a thermal power plant?
What does an economizer do in a thermal power plant?
Preheats cold feedwater using hot waste gases from the boiler, increasing efficiency.
What is the function of a superheater?
What is the function of a superheater?
Raises the temperature of steam, making it more powerful for the turbine.
