    Abstract: A biomass-mixed, pulverized coal-fired burner is provided. The biomass-mixed, pulverized coal-fired burner is capable of burning biomass fuel as auxiliary fuel in large quantities and burning only pulverized coal when the biomass fuel is not sufficiently available. The biomass-mixed, pulverized coal-fired burner includes: a biomass fuel jet nozzle that extends axially along the biomass-mixed, pulverized coal-fired burner; a pulverized coal fuel jet nozzle that surrounds the biomass fuel jet nozzle; a secondary air nozzle that surrounds the pulverized coal fuel jet nozzle; and a tertiary air nozzle that surrounds the secondary air nozzle. A biomass fuel stream is jetted into an inside of a pulverized coal fuel flame formed in a furnace, the flame offering favorable ignition and flame holding performance.

    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: Disclosed is a burner for oxidant gasification of pulverized fuels under high pressures, e.g. 80 bar, and temperatures, e.g. 1200 to 1900° C., in reactors with liquid slag removal for oxygen gasification. The individual pulverized coal supply tubes in the burner are inclined toward the burner axis in the direction of the burner mouth, are implemented equiareally from the burner inlet up to the burner outlet, and end at the burner mouth adjacent to the oxidant outlet. Owing to the pulverized fuel feeding elements being implemented right up to the burner mouth and the instantaneous entry of the pulverized coal into the rotating oxygen stream there is no longer any areal discontinuity at the dust outlet, since here the pulverized coal stream is immediately sucked into the oxidant stream. At the outlet of the media the individual pulverized coal streams merge into a single rotating pulverized coal/oxygen stream, thereby achieving an even flame spread and stabilization.
