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.

Rankine cycle - Wikipedia

The Rankine cycle is a model used to predict the performance of steam turbine systems. It was also used to study the performance of reciprocating steam engines. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing phase change. It is an idealized cycle in which friction losses in each of the four components are neglected.

Understanding Steam & Boiler Heating Systems | HomeAdvisor

Boiler Systems Operation. In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.
