Abstract (en)
[origin: EP0559619A1] The combustion air is supplied to the combustion chamber (3) as primary air and secondary air via a throttling arrangement (10). A slide (21) provided with slots (23) is actuated either by hand or time-dependently by motor-moved adjustment members. The primary air is supplied via a frame to the underside of the furnace grate (25). The secondary air passes via two vertical ducts (30) arranged inside the combustion chamber (3) into a transverse duct (34), from which it flows out in a preheated state through slots downwards into the combustion chamber (3). As a result of this air guidance, the combustion process can be optimised, the harmful-substance content of the waste gases can be reduced and the efficiency can be improved. <IMAGE>
