1. be uniformly distributed with the liquidate hotblast stove of the steady flame of spray combustion backflow preheat of nozzle in the settling chamber;

  • Comprise that settling chamber body of wall, settling chamber, combustion chamber body of wall, combustion chamber, gas inlet pipe, air intake duct, coal gas distribute circuit, air to distribute circuit, gasburner, air nozzle and heat storage;

    It is characterized in that;

    Heat storage is made up of first heat storage (8a), second heat storage (8b), the 3rd heat storage (8c) and the 4th heat storage (8d);

    Settling chamber body of wall (1) is that top spherical vault and following cylinder constitute;

    The intravital space of settling chamber wall is settling chamber (2);

    Vertical its axis from up to down is respectively arranged with gas inlet pipe (3) and air intake duct (4) on the cylinder of settling chamber body of wall (1);

    Gas inlet pipe and air intake duct are vertical respectively or tilt to be connected the air distribution circuit (5b) that the coal gas of building by laying bricks or stones at settling chamber body of wall (1) internal upper part distributes circuit (5a) and bottom;

    Coal gas distributes circuit and air to distribute the circuit cross section to be rectangle;

    The corresponding respectively gasburner (6a) and air nozzle (6b) that is provided with the dozens of square-section on the inboard ringwall separately;

    Gasburner is crooked downwards and air nozzle (6b) is upwards crooked and the mixing nozzle that liquidates (6c) evenly arranged along the interior ringwall horizontal radial of settling chamber docks;

    Combustion chamber body of wall (1a) is linked together by the conical shell at the great circle cylindrical shell of the little cylinder of upper end, lower end and middle part and constitutes;

    Be connected through the arc transition between top and bottom and conical shell, hot-blast outlet pipe (14) is arranged on the great circle cylindrical shell, the inboard roundlet cylindrical shell outside with combustion chamber body of wall (1a) upper end of the cylinder of settling chamber body of wall (1) is each other that the slippage shape connects together;

    Regenerator (8) is arranged in columnar hotblast stove body of wall (7) at the bottom, combustion chamber (2a) in the combustion chamber body of wall (1a);

    Fire grate (9) and the pillar stiffener (9a) that places in the hotblast stove body of wall (7) arranged at the bottom of regenerator, has in the regenerator (8) from fire grate (9) to pile up first heat storage (8a), second heat storage (8b), the 3rd heat storage (8c) and the 4th heat storage (8d) in combustion chamber (2a) upward, and the hotblast stove body of wall (7) of fire grate (9) bottom is interior to be cold air chamber (10);

    Smoke outlet tube (13) and cold wind inlet pipe (12) are arranged on the side wall of cold air chamber, be mutual slippage shape between hotblast stove body of wall (7) and the combustion chamber body of wall (1a) and connect together.
