PROBLEM TO BE SOLVED: To suppress the falling of a fuel to the bottom of a furnace and control the grain size of the solid fuel. SOLUTION: In this combustion system for burning by supplying the solid fuel to a burner installed in the wall of a combustion furnace, the solid fuel is supplied to the burner after being crushed to variably control its grain size and the crushed grain size of the solid fuel is varied according to a load on the combustion furnace. Also, the burner is formed of burners 2a to 2d in multiple stages having different furnace wall arrangement heights, and the crushed grain size of the solid fuel is varied according to the arrangement height of each burner. In addition, the grain size of the solid fuel is varied according to the load on the combustion furnace and the arrangement height of each burner. The crushed grain size is increased when the load on the combustion furnace is large or the arrangement height of the burner is high. COPYRIGHT: (C)2005,JPO&NCIPI
