    Abstract: This solid fuel burner (1) is provided with: a nozzle (9) that is provided around the central axis of the burner, that includes a straight tube section (2) having an opening opposed to a furnace (13), and a curved tube section (5) continuous with the straight tube section (2), and that sprays out, from the opening to the furnace (13), a fluid mixture which is of a solid fuel and carrier gas of the solid fuel and which is flowing in the curved tube section (5); a first swirler (6) that gives the fluid mixture a swirl at the burner central axis side of the straight tube section (2); and a second swirler (7) that gives, at the burner central axis side downstream of the first swirler (6), the fluid mixture a swirl opposite to that given by the first swirler (6). The fluid mixture flowing from the curved tube section (5) is moved radially from the central axis by the first swirler (6), and is given a counter-swirl by the second swirler (7) to reduce swirl intensity.

    Abstract: The present invention relates to a cylindrical non-melt and partial melt type entrained flow bed gasifier with one or more burners mounted on the top thereof for supplying pulverized raw coal and oxidizer thereto, wherein each of the burners comprises three or four pipes so as to form a central supplying line for injecting the pulverized coal with a carrier gas into the gasifier, a primary oxidizer annular region around the central supplying line having a plurality of primary oxidizer supplying bores for injecting primary oxidizer vertically or at an angle to the injection region of the pulverized coal supplied through the central supplying line so as to direct the pulverized coal to the central region, and an outer cooling annular region around the primary oxidizer annular region for flowing cooling water, which is operated preferably at a temperature range of 1,250∼1,450°C, or of 1,150∼1,500°C according to the properties of the coal. According to the present invention, the pulverized coal and oxidizer are properly mixed, and the pulverized coal is directed towards the middle of the gasifier, so that the reaction is completed with the ash being wholly non-melted or partially melted.

    Abstract: 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.
