In the furnace after at the bottom of the gas furnace grate uniform wind, the ash heat heating of the reverse downward into the fire gasification layer (1000 to 1200 DEG C) and hot carbon gasification reaction occurs, the heat of formation crude gas to new furnace coal drying and from the gas occurrence furnace outlet is derived, the exit gas temperature ranging from 500 to 600 DEG C, the main component for CO, H2, CO2, N2. Where CO and H2 are the active components of the gas, which belong to the heating gas, N2 is the air component of the gasification agent. Gasifier bed height is 1.3m ~ 1.8m, from top to bottom can be divided into ash layer, gasification layer, reaction layer, dry distillation layer. Into the furnace of coal after crushing, screening, size 13 ~ 25mm, 25 to 50, or 40 ~ 60mm, through the skew bridge by coal hoisting device added to double bell cover coalbox. The coal distributor into the furnace.Purification treatmentBy the gas occurrence furnace production of crude and hot gas (temperature of 500 to 600 DEG C) first by gravity dust collector, the large particle dust in the gas by weight part fall into the bottom tube, and then entered with the water seal isolation of cyclone further dust, the secondary dust removing gas by coal gas pipeline transported to gas.Single stage hot gas station process flow diagram
