摘要： PROBLEM TO BE SOLVED: To surely prevent sulfur oxide form generating, and also, improve the combustibility by a method wherein a plurality of mixing nozzles where a residual oil and an atomized medium are mixed and atomized, are arranged on concentric circles, and a plurality of mixed liquid nozzles to feed a mixed liquid of water and magnesium, are provided in the vicinities of respective mixing nozzles. SOLUTION: A mixed liquid 12 which is fed by a feeding device of the mixed liquid of water and magnesium, is fed to a mixed liquid nozzle chamber 14 being provided at the center on the upstream side of a burner tip 5, from the rear center of a burner gun 2 through a mixed liquid feeding pipe 13. The mixed liquid 12 having passed the mixed liquid nozzle chamber 14, is dispersed and fed to a plurality of mixed liquid nozzles 15, which are provided on the internal side of mixing nozzles 11 by the same number as the mixing nozzles and at the same angle of the mixing nozzles, and is respectively atomized in combustion furnaces or boilers. The atomized mixed liquid 12 is mixed with a residual oil and an atomized medium and a mixed gas, right after having been atomized, and the three fluids become one mixed gas, and are burnt and dispersed, and sulfur oxide is suppressed from generating.

摘要： PURPOSE: To simplify a burner as a whole by reducing the height of a burner panel in a burner which is adapted to burn a gas mixed with two kinds of pulverized coal, dense and thin. CONSTITUTION: A density separator 13 is provided inside a pulverized coal pipe 05 to form a pulverized coal mixed gas of a high concentration at an outer circumference part and that of a low concentration at the center of one pulverized coal pipe. This reduces a dense mixed gas burner and a thin mixed gas burner to one unit, through two separate burners are used in the prior art.

摘要： PURPOSE: To provide a reductor burner for a coal gasification oven which is so constructed as to prevent troubles such as those in feeding coal for gasification caused by slag deposited and accumulated on the burner. CONSTITUTION: A reductor burner 9 is installed rotatably and rotated through a gear 17 by a driving motor 16. A water-cooled scraper 21 with a rectangular cross-section is installed just below the burner 9. When the burner 9 is rotated, slag deposited on the burner 9 is rotated too, hits against the scraper 21 to be scraped, and falls down. Hence, a cylindrical slag does not grow on the burner 9.

摘要： PURPOSE:To prevent the blockage of a reductor and diffuser unit for two-stage type coal gassifying furnace due to the adhesion and accumulation of molten slug or char. CONSTITUTION:Steam injection nozzles 16 are arranged at a part of a diffuser 5 and a reductor 6 and steam is injected along the surface of a refractory 3 whereby molten slag and/or char adhering to the refractory 31 is separated by the injecting energy of the steam.

摘要： PURPOSE:To realize good ignition performance and flame formation by providing a fuel injection port directed inwardly with regard to the axis of a burner and a plurality of fuel injection ports directed outwardly with regard to the axis of the burner in a plurality of gas fuel nozzles arranged on a circumference which is concentric with the burner axis. CONSTITUTION:A plurality of gas fuel nozzles 3 are provided on a circumference which is concentric with the center axis of a burner, and a plurality of gas fuel injection holes 9 directed somewhat outwardly with regard to the center axis of the burner are provided in the respective gas fuel nozzles, and a certain number of other gas fuel injection holes 13 directed inwardly with regard to the center axis of the burner are also provided. Gas fuel 8c injected from the gas fuel injection holes 13 is supplied to after flow part right after a flame stabilizer 2 and is diffused and mixed with primary air 7b to form a stable ring flame 10. Even in a burner which uses as combustion gas fuel gases ranging from gas turbine exhaust gas to air, good ignition performance and flame formation can be realized.
