COMBUSTION OVEN AND PROCESS FOR PRODUCING FUEL FROM REFUSE

摘要

Industrial oven for the combustion of solid, liquid, pasty or gaseous fuels, comprising at least two fluidized beds (14) traversed by hot gas from the bottom and which are offset in height in the transport direction of the fuel into the combustion chamber (35) according to a reciprocal delimitation one behind the other and in step, after adjusting a mean combustion temperature between preferably 500 et 800C. It is further possible to recover from household refuse and/or industrial refuse similar to household refuse a fraction of fuel rich in energy and lean of noxious products by preparation by means of drum sieves, hammer crushers and bar and crank screens of a particulate size comprised between 120 and 500 mm.
