Two-stage gas producer technological process
The two-stage gas producer is composed of the retorting section and the gasification section from top to bottom. First, the coal enters the furnace body from the top coal bunker through the two lower coal valves. After full drying and long-term low-temperature retorting in the retorting section, the coal gradually forms semicoke and enters the gasification section. The hot semicoke fully reacts with the gasifying agent bubbling in the furnace bottom in the gasification section, and forms ash through the reduction layer and oxidation layer in the furnace, It is automatically discharged from ash basin driven by grate. In the process of low-temperature carbonization of coal, the gas generated mainly by volatilization analysis is called carbonization gas, which forms the top gas, accounting for about 40% , its calorific value is high（ 6700KJ/nm ）Low temperature（ one hundred and twenty ° C ）And contains a large amount of tar. This tar is the product of low-temperature dry distillation with good fluidity, and can be captured by coke catcher as chemical raw material and fuel. In the gasification section, the hot semi coke undergoes a series of chemical reactions such as reduction and oxidation to generate gas, which is called gasification gas. The bottom gas of two-stage furnace accounts for about 60% , its calorific value is relatively low（ 6400KJ/nm ）, high temperature ( 450 ° C about ) Since the low temperature carbonization time of coal in the carbonization section is sufficient, the coal entering the gasification section has become semi coke, so the generated gasification gas does not contain tar, and is close to the ash layer of the furnace grate, so it contains a small amount of fly ash. The bottom gas can be treated by cyclone dust collector, air cooler and other equipment.
