Grate Fired Boiler design: sofware for Stoker fired,

Fuel burns on firing grate generating heat. Some of the fuel is burnt as soon as it enters the furnace in air and is called suspension firing. This heat is absorbed by various boiler heat transfer sections and used to convert water into steam. Depending up on the fuel type and it's characteristics, a suitable grate is selected for firing purpose.
