ABSTRACT:
The combustion system for implementing the process has a combustion grate, hoppers below the combustion grate for supplying primary combustion gas through the grate and nozzles that lead into the furnace above the combustion grate to supply secondary combustion gas. At least one extraction duct for flue gas is provided at the rear end of the furnace above the combustion grate. This duct is connected to the suction side of a fan. The pressure side is connected to nozzles arranged in the upper area of the flue gas pass. The nozzle height allows the flue gases a residence time of at least 1 second after secondary gas is supplied.
