PURPOSE:To obtain a method of burning to decrease generation of NOx for pulverized coal, without lowering combustibility, by injecting pulverized coal from the center part of a burner, and the other fuel than pulverized coal, from the outer periphery of the burner. CONSTITUTION:Combustion is taken place in such a manner that pulverized coal is injected from a fuel passage II, provided in the vicinity of the center part of a burner, and the other fuel than pulverized coal, such as COG, from a flow path III, uniformly arranged to the outer periphery of a burner. By this method of burning. NOx can be decreased, without lowering the combustibility of the fuel. |
