Steam Power Plant - an overview | ScienceDirect Topics

Dipak K. Sarkar, in Thermal Power Plant, 2017. 10.1 Introduction. In a steam power plant, atmospheric air is fed into the furnace of a steam generator for combustion of fossil fuel (coal, fuel oil, and fuel gas), generating heat released by burning of fuel. Hence, it is essential that fuel is burnt completely in the furnace to release as much ...
