摘要
PROBLEM TO BE SOLVED: To provide a pulverized coal burner and a low ash melting point sub-bituminous pulverized coal combustion method using the pulverized coal burner capable of controlling a sticking part or a sticking quantity of slag in a furnace.;SOLUTION: This pulverized coal burner injecting a pulverized coal mixture together with a combustion air into the furnace to carry out turning combustion, has a pulverized coal mixture nozzle and a combustion air nozzle arranged surrounding the pulverized coal mixture nozzle. The pulverized coal mixture nozzle is provided with a pulverized coal concentration distribution adjusting block for a pulverized coal mixture, provided with an adjusting means for adjusting a projecting degree, at least at one part in the nozzle, and a flux rotating plate for the pulverized coal mixture downstream of the block. The projecting degree of the block is adjusted according to the quality of pulverized coal to change the nozzle cross section inner distribution of pulverized coal. The sticking part or sticking quantity of slag can thereby be controlled.;COPYRIGHT: (C)2005,JPO&NCIPI
