Coal gasification and rational utilization of coal conversion is one effective way, in line with China's development
of clean coal technology, energy diversification strategy, China has both the current and long-term significance.
In recent years, pressurized moving bed and entrained bed, fluidized bed ash agglomeration and airflow bed gasification
technology have been rapid development, at present, as small and medium scale atmospheric fixed-bed gasification fuel
gas main supply unit scale of production, the cost of investment,construction period, which qualify for the majority
of metallurgical, chemical, building materials and machinery industries such as gas demand is widely used.Press the gas
furnace production process characteristics distinguish its furnace solid materials are generally divided into five,
namely dry layer, carbonization layer, the oxide layer, reducing layers and layers of ash. Wherein the oxidizing and
anoxic layers has been referred to as the gasification reaction layer, the oxide layer of carbon is oxidized by oxygen
in the gasification agent into carbon dioxide and carbon monoxide, and release a lot of heat, gas heat produced by the
chemical reaction heat required for this to maintain the temperature of the oxide layer is generally maintained at
1100 ~ 1250 ℃; reducing layer is a region of combustible gases generated key, carbon dioxide and hot work, an endothermic
chemical reaction, producing combustible carbon monoxide; steam and hot endothermic carbon chemical reaction to produce
carbon monoxide and hydrogen flammable, and absorb a large amount of heat. Furnace properly maintained at all levels,
especially the oxidized and anoxic layers of temperature, altitude and balanced degree of maintenanceis essential,
otherwise there may be cold run, hot run or partial operation of such abnormal furnace conditions, thus affecting the Gas Station
of normal production.
