coal processing in a boiler - waldemarpanek.pl

Stage 1 The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2 The second stage is the thermodynamic process. 1. The heat from combustion of the coal boils water in the boiler to produce steam.
