    摘要： The pulverized coal burner suitable for lowering the concentration of nitrogen comprises a pulverized coal nozzle (10) for jetting a mixture of pulverized coal and primary air, a secondary air nozzle (11) and a tertiary air nozzle (12), concentrically arranged around the outer periphery of the pulverized coal nozzle (10), and a tube expanded portion (20) at the end of a partition wall separating two adjacent air nozzles. A flow shift means for shifting the secondary air in the secondary air nozzle so as to flow along the tube expanded portion, for example a guide plate (61), is provided. The secondary air comes to be jetted outward by the guide plate, and mixing of the secondary air and the tertiary air with pulverized coals is delayed, whereby an amount of occurrence of NOx can be decreased. The guide plate (61) is a ring disposed in an outlet region of the secondary air nozzle (11), which ring has a taper-shaped ring portion for guiding a part of the secondary air (52) in a radially outward direction.

    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.
