1. a pressurization static bed slag gasification furnace, is characterized in that, it comprises:

  • The coal lock, it is positioned at transitional storehouse top, for getting coal from coal bunker off and on, the backward pressurized gasification container coal that pressurizes, then pressure release is got coal from coal bunker, completes a circulation;

    Transitional storehouse, it is the passage between coal lock and vapourizing furnace, is convenient to rely on gravity to add the pressurized gasification container in the coal in the coal lock;

    The pressurized gasification container, it is between transitional storehouse and connecting short section, utilize nozzle to introduce vaporized chemical by the gasification vessel of carbonic solid fuels burning and gasification in the fuel of pressurized gasification container bottom, wherein said pressurized gasification container has for discharging top raw gas outlet pipe and the bottom slag bath of raw gas, and described bottom slag bath is collected slag and discharged slag by slag-drip opening;

    Connecting short section, it is positioned at vapourizing furnace bottom and top, shock chamber, for connecting pressurized gasification container and shock chamber;

    Shock chamber, it is the water-filled vessel between connecting short section and slag lock, for Quench, cooling and remove slag heat;

    AndThe slag lock, it is the container that is positioned at the bottom, shock chamber, for store glass matter solid impurity particle and by cone valve, the solid slag particle is discharged out-of-bounds.
