    1. Spinning burner for coal gasification reactors, in which a producer gas containing carbon monoxide and hydrogen is produced by partial oxidation of solid materials containing carbon in the presence of water or steam and of oxygen or air, consisting of a plurality of pipes (20, 21) arranged concentrically to one another for the separate supply of the solid particles and of the gasification medium, with guiding elements built into the conduit (21) for the oxygen or air for production of the spin of the materials emerging from the burner (6) and reacting with one another, characterised in that movable guide elements (34, 40, 61, 77) are present in the nature of a helix, shaped as a spiral spring and supported at least one one side, which have an adjustable angle of inclination of 20-70 degrees with respect to the longitudinal direction of the supply.

    This invention relates to the combustion of highly watered solid fuels. :
    Known burners for coal gasification, containing channels for the supply of aqueous suspension and oxygen-containing gas, and the output section of the channels are made conical Cl3.
    However, during the coal gasification process, slag is formed, which must be removed from the resulting gas stream. Slag is removed with a water bath. Insufficient removal of slag leads to unreliable operation of the burner.
    Burners containing coaxial channels with conical exit sections are also known, one of which is water-cooled, one designed to supply coal suspensions and the other oxygen-containing gas, the latter being provided with inclined guide plates and streamlined body-C2 J .
    A disadvantage of such a burner is also incomplete combustion of coal, which leads to slagging of the exit portions.
    The purpose of the invention is to increase the completeness of combustion of coal.
    The goal is achieved by the fact that in a burner containing TAC channels with conical outlet sections, one of which is water-cooled, one channel is designed to supply water to the coal slurry, and the other is oxygen-containing gas, the latter: The flow plates and the streamlined body, the guide plates are set at an angle of 20-70 ° to the longitudinal axis, and the length of the channel section on which the guide plates are placed is 0.01-0.4 of its diameter.
    In addition, the guide plates can be made movable.
    FIG. 1 shows a burner, a longitudinal section / in FIG. 2 - securing the upper part of the movable guide plate; Fig. 3 shows the fixing of the lower part of the movable guide plate.
    The coal gasification burner contains coaxial channels 1 and 2 with conical outlet sections 3 and 4. The conical outlet section 3 of channel 1 is water-cooled. KahnSH 1 is intended to supply coal with a water suspension, and a channel 2 for supplying oxygen-containing gas. Channel 2 has a streamlined body 5 and a guide plate bent obliquely relative to its surface.
    The guide plates 6 are installed at an angle of 20-70 to the longitudinal axis, and the length of the channel section on which the guide plates are placed is 0.01-0.4 of its diameter. The guide plates b can be made movable and fixed to the upper and lower parts on the walls of the channel 2.
    The transverse form of the plates can be rectangular, circular or other.
    The length of the plates should form at least one inscribed angle from 60 to 300 °.
    The burner works as follows.
    The aqueous suspension of the coal is pumped after wet grinding and mixing to the burner through channel 1. The channel 2 supplies the oxygen-containing gas necessary for combustion. At the exit of the burner, partial oxidation of coal particles occurs in the presence of water. . As a result of this reaction, carbon monoxide and hydrogen-containing synthesis gas are formed. At the same time, liquid slag particles are formed. In the conical output sections to: the canals 1 and 2, the output flow velocities increase. The streamlined body 5, installed in square 2, prevents hydraulic losses inside the channel. The guide plates 6 installed in the channel 2 allow to obtain a spin-on flow of oxygen-containing gas. The twist is determined by the angle of inclination of the plates, which may vary during operation, since the plates are made movable. The degree of swirling of the oxygen-containing gas affects the completeness of the combustion of the coal.
    At. Gasification; coal is desirable not only a high degree of combustion of coal, but also the prevention of slag formation. When installing the guide plates at an angle of 20 ° to the longitudinal axis on a section of the channel of a length equal to 0.01-0.4 of its diameter, the degree of coal combustion is 98% with the formation of 2% floating slag. If the angle of inclination of the plates is 70 with the dimensions of the channel section lO, 01 and the diameter, then the degree of combustion of coal will be 99% and 99.7%, respectively. In this case, no floating slag is formed.
    If the angle of inclination is 10 ° with a channel section size of 0.01 and 0.4, the degree of coal combustion is 90% (with formation of 20% floating slag) and 92.5% (with formation of 16% floating slag if the slope angle is 80, with dimensions of 0.01 and 0.4 of its diameter, then the degree of coal combustion is 98.5% (with the formation of 1% floating slag | and 99.3% (without formation of floating slag / respectively, if the angle of inclination is 20 with dimensions of 0.005 and 0.5, the degree of combustion of the angle is 93.2% (with formation of 12% floating slag) and 99% (without formation of a floating slag) Respectively, and with a tilt angle of 70 °, with dimensions of 0.005 and 0.5 trum397, the coal stump is 93.6% (with formation of 10% floating slag and 99.6% (without formation of floating slag J, respectively. Thus, to ensure the most complete combustion of the coal and prevent slag formation, the guide plates must be installed at an angle of 20-70 ° to the longitudinal axis in the section of the kangsh length 0.01f-0.4 of its diameter.
