るように形成したもの。[Claims for Utility Model Registration] 1. In a device in which burner groups in multiple stages are arranged on a furnace wall and these burner groups and a crusher are connected through a pipe, at least one of the burner groups in the multiple stages A plurality of crushers are connected to the burners in each stage for each burner group in the above stages, and when some of these crushers are stopped, the number of burners in each stage is equal to the number of ignited burners in each stage. A pulverized coal combustion device configured so that the unit ratio approximately corresponds to the stage unit ratio of the ignition burner during rated operation. ~ 2 In the pulverized coal combustion apparatus according to claim 1 of the utility model registration, two pulverizers are connected to each burner group in each stage, and adjacent burners in each stage are connected to each other. A pipe connected to the machine. 3. In the pulverized coal combustion device according to claims 1 and 2 of the claims for utility model registration, there are three groups of burners: upper, middle, and lower, and the number of installed burners in the upper burner group is equal to the number of burners in the middle or lower burner group. The number of burners installed is twice as many, and the upper burners are arranged so that every other burner receives fuel from a designated crusher, and the fuel is distributed through multiple distributors that classify multiple burners as one part. It is formed so that it can be supplied respectively.
