摘要： Subject
A solid fuel burner and its combustion method suited for encouraging fuel ignition and avoiding slugging caused by combustion ash, wherein a gas of low oxygen concentration (exhaust combustion gas) is used as a carrier gas of such a low grade solid fuel as brown coal.
Means for Solving the Subject
An additional air nozzle (12) for jetting additional air having a velocity component in the circumferential direction of a fuel nozzle (11) is provided in the fuel nozzle (11), thereby encouraging mixing between the fuel and air in the fuel nozzle (11). Further, the amount of air supplied from the additional air nozzle (12) is adjusted in response to the difference in combustion loads. Under light load, the amount of air supplied from the additional air nozzle (12) is increased so as to increase the oxygen concentration of the circulating flow (19) formed downstream of the outside of the outlet of the fuel nozzle (11), whereby stable combustion is ensured. Under heavy load, by contrast, the amount of air supplied from the additional air nozzle (12) is decreased, and a flame is formed away from the fuel nozzle (11) in such a way that burner structures and furnace wall will be less subjected to radiant heat.
