GASIFICATION MELTING EQUIPMENT AND METHOD OF FEEDING AIR FOR COMBUSTION IN MELTING FURNACE OF GASIFICATION MELTING EQUIPMENT

摘要

A gasification melting equipment and method of feeding air for combustion in a melting furnace of gasification melting equipment, devised to prevent sticking of clinker to a superior area internal wall of primary combustion chamber of melting furnace. The gasification melting equipment (10) comprises a gasification furnace (20), a melting furnace (30) capable of combusting pyrolysis gas contained in produced gases therefrom and also converting ash contents to a fused slag and a gas duct (40) for guiding the produced gases within the gasification furnace (20) to a produced gas introduction port of the melting furnace (30). The produced gas introduction port of the melting furnace (30) is provided on a superior area side wall of primary combustion chamber (31) thereof. The gas duct (40) in the vicinity of the produced gas introduction port is provided with primary combustion air supply nozzles (41a-41c, 42a-42c) for supply of combustion air amounting to 70% or more of the total quantity of combustion air for the primary combustion chamber of the melting furnace (30).
