我站是冷煤气发生站,安装有3-AД-13型煤气炉。生产流程:煤气发生炉→双联竖管→电捕焦油器→洗滌塔→煤气加压机→用户。我站在1958年5月末刚投入生产时,气化强度只有200—250kg/m~(2-)时,煤气发热量只有1300—1400大卡/m~3,灰渣含炭量经常高达30—40%,有达到50%以上。但经过1958年生产大跃进以后,我站的气化强度提高到450—550kg/m~(2-)时,有的试验炉高达800 kg/m~(2-)时,煤气发热量提高到1450大卡/m~3以上,灰渣含炭量降低到20%左右。具体经验总结如下。
I stand is a cold gas station, installed 3-AД-13-type gas stove. Production process: gas furnace → double vertical pipe → electric capture tar → washing tower → gas pressure → user. When I stood at the end of May 1958, just put into production, the gasification intensity is only 200-250kg / m ~ (2-), the gas calorific value is only 1300-1400 kcal / m ~ 3, ash content of carbon often up to 30 -40%, have reached more than 50%. However, after the Great Leap Forward in 1958, the gasification intensity of our station was increased to 450-550kg / m ~ (2-), while in some test furnaces up to 800 kg / m ~ (2-), the calorific value of the gas increased to 1450 kcal / m ~ 3 above, carbon content of ash reduced to about 20%. The specific experience is summarized as follows.
