目前 ,我国化肥企业的造气工段仍然在使用固定层间歇式煤气发生炉生产原料气。可以说造气工段水平的高低 ,基本上决定了一个企业生产的好坏 ,制约着企业的发展。因为单炉发气量高 ,一般意味着气量大、气质好、氢氮比稳定、消耗低。相反单炉发气量小 ,说明气量小、气质差、消耗 At present, China’s fertilizer business gas station is still using fixed-layer intermittent gas furnace production of feed gas. It can be said that the level of gas-making section of the level, basically determines the quality of a business, restricting the development of enterprises. Because a single furnace gas volume, generally means that the gas volume, good temperament, hydrogen and nitrogen than the stable, low consumption. On the contrary, a single furnace gas evolution is small, indicating a small amount of gas, poor temperament, consumption
