Abstract

The inner space (16) of the refuse feed grate (3) is connected to the suction side of a flue gas blower (18) and the feed conduit (19) with the pressure side of the flue gas blower (18). The flue gas load conduits (20,21,22,23) equipped with regulating and cut-off components (24) are connected to the fresh air load conduits (11-14) likewise equipped with regulating and cut-off components (15). The fresh air load conduits are on the one hand connected to the air box (5a-5d) of the zones (4a-4d) below the grates, and on the other hand via the fresh air conduit (10) with the fresh air blower (9). The refuse feed grate and the combustion grate (4) are formed as a common unit. USE/ADVANTAGE - For wet refuse burning boiler,with simple,low-cost design and low environment pollution.
