Embodiment 1
[0057] A process for a coal gasification device, comprising the steps of:
[0058] Step 1. After mixing the coal gasification raw materials, they enter the combustion chamber 9 of the gasification furnace 1 through multiple burners 10 for combustion; the above-mentioned combustion is carried out under a high pressure of 4.0-8.7 MPa and an environment of 1200-1600 ° C; The gas compressor 5 compresses the synthesis gas in the synthesis gas outlet pipeline of the water washing tower 4 and sends it to the quenching ring 16; the water outlet on the upper part of the sediment tank 7 makes the black water enter the first jet in the gasification furnace 1 through the pump 45 respectively. Water ring 17, second water spray ring 27 in cyclone separator 2, several waste heat boiler water inlets 36 and water washing tower water inlets 42, gasifier water outlet 14, cyclone separator water outlet 28, several waste heat boiler outlets The black water in the water port 37 and the water washin...
