<P>PROBLEM TO BE SOLVED: To accurately predict possibility of generation of large lumps of clinker ash in order to stably operate a heating furnace, and by extension, to suppress attachment of ash. <P>SOLUTION: A clinker composition of a solid fuel for evaluating existence of generation of large lumps of clinker ash is calculated, the existence of generation of large lumps of clinker ash is evaluated based on an iron component content in the clinker composition and a reference value of the iron component content for reducing the generation of large lumps of clinker ash is calculated (S101 to 103). When the solid fuel to be used is a solid fuel of a single sort, the solid fuel of the single sort of which the iron component contents in the clinker composition is the reference value or less is selected, and when the solid fuel to be used is solid fuels of a plurality of sorts, the solid fuels are mixed at a predetermined mixing ratio in which the iron component content in the clinker composition is the reference value or less and the mixed solid fuel is supplied as a fuel (S104 to 106). <P>COPYRIGHT: (C)2013,JPO&INPIT |
