FIELD: gas industry.
SUBSTANCE: invention relates to gas industry. Operation of gasifier gateway with fixed bed of coal is performed by coal loading in gateway through one hole and unloading of coal from gateway through other hole into reactor under excess pressure of process gas. Both holes are equipped with self-sealing gates. Before gateway filling pressure is reduced to ambient pressure and gateway is blown-off by inert gas. After gateway filling with coal at mechanically closed hole pressure in gateway is increased with help of inert gas to such values that self-sealing gate hermetically closes hole. Prior to emptying pressure in gateway is increased by means of process gas to pressure in reactor.
EFFECT: higher efficiency and reliability, simplified operation of gateway are provided.
