Effect of the temperature of different combustion zones in

Therefore, during combustion in grate boilers hard coal passes through three phases: drying, degassing and burn-out of the produced coke. In the first section of a grate, coal is heated up by absorbing heat from the combustion chamber walls, already burning coal and air passing through the coal layer on a grate.
