摘要： A boiler operating method operates a boiler by switching between air combustion mode and oxygen combustion mode when burning fossil fuel with first combustion gas and second combustion gas. The second combustion gas compensates for oxygen deficiency in the first combustion gas. The air combustion mode uses air as the first combustion gas and the second combustion gas while the oxygen combustion mode uses mixed gas of combustion flue gas and oxygen-rich gas as the first combustion gas and the second combustion gas, the combustion flue gas being produced when the fossil fuel is burned. By mixing the oxygen-rich gas in the air in the process of switching between air combustion mode and oxygen combustion mode, the air being the first combustion gas used in the air combustion mode, the boiler operating method can switch between the air combustion mode and oxygen combustion mode while maintaining stable combustion.

摘要： To provide a pulverized coal burner capable of reducing the NOx concentration at the time of a low load, a pulverized coal burner includes a secondary air nozzle and a tertiary air nozzle concentrically positioned about the outer periphery of a fuel nozzle carrying a pulverized coal with a primary air, and two swirling flow generators are included at least one of these nozzles with a positional relation parallel to a flow of air. One of the swirling flow of the two swirling flow generators can be set strongly. And, under a condition of low air flow rate, air can be supplied from one swirling flow generator alone. Since the swirling strength of the combustion air can be increased, the concentration of NOx produced by the combustion of the pulverized coal can be reduced. Also, because the swirling strength at the time of low load can be increased, the NOx concentration can be reduced by keeping the pulverized coal flame stable.

摘要： A solid fuel burner using a low oxygen concentration gas as a transporting gas of a low grade solid fuel such as brown coal or the like and a combustion method using the solid fuel burner are provided. The solid fuel burner comprises a means for accelerating ignition of the fuel and a means for preventing slugging caused by combustion ash from occurring. Mixing of fuel and air inside a fuel nozzle 11 is accelerated by that an additional air nozzle 12 and a separator 35 for separating a flow passage are arranged in the fuel nozzle 11, and the exit of the additional air nozzle 12 is set at a position so as to overlap with the separator 35 when seeing from a direction perpendicular to a burner axis, and additional air is ejected in a direction nearly perpendicular to a flow direction of a fuel jet flowing through the fuel nozzle 11. An amount of air from the additional air nozzle 12 is varied corresponding to a combustion load. By increasing the amount of air from the additional air nozzle 12 at a low load operation, an oxygen concentration of a circulation flow 19 formed in a downstream portion outside the exit of the fuel nozzle 11 is increased to stably burn the fuel. By decreasing the amount of air from the additional air nozzle 12 at a high load operation, a flame is formed at a position distant from the fuel nozzle 11 to suppress radiant heat received by structures of the solid fuel burner and walls of the furnace.
