METHOD FOR CONTROLLING AIR-COOLED WALL SURFACE TEMPERATURE FOR COMBUSTION FURNACE, AND COMBUSTION FURNACE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To prevent generation/adhesion of clinker on the surface of an air-cooled wall in a combustion furnace including the air-cooled wall around a combustion chamber, as well as achievement of reduction of energy consumption and simplification of facility.;SOLUTION: According to the case (1) of a high rank, the case (2) of a middle rank, and the case (3) of a low rank in terms of the quality of trash of burnable trash loaded, the amount of loading of cooling air supplied to an air-cooled wall is controlled/regulated by using, as an index, any one of or a combination of a heat value of the trash, a gas temperature of the combustion chamber, and a surface temperature of the air-cooled wall.;COPYRIGHT: (C)2014,JPO&INPIT
