1 我国造气风机的使用现状我国的小氮肥工业历经了 40年的发展历程 ,与其相关的造气鼓风机性能亦得到了相应的改善和提高。初期 ,造气炉炉膛直径≤ 2 0 0 0 ,合成氨规模在 3～ 5ｋｔ ａ ,当时国内没有专门为小氮肥配套的造气风机 ,均采用工业上通用的小流量、低压头的8- 1 8
1 China’s use of gas-generating fan status China’s small nitrogen-fertilizer industry after 40 years of development history, and its related gas-generating blower performance has also been improved and improved accordingly. In the early stage, the diameter of gasifier furnace was ≤ 2000 and the scale of ammonia was 3 ~ 5kt a. There was no gas-making blower specially matched for small nitrogen fertilizer at that time in China. All the gas-generating fans used in industry were low-flow and low-pressure heads
