我厂用HTD85－21高效节能鼓风机，取代了原使用的80m3／min和42m3／min两台并联的罗茨式鼓风机，二年多来，经数百炉次的生产实践，取得了满意效果。一、两种风机性能对比HTD85－21节能鼓风机能否替代罗茨鼓风机用于5t／h冲天炉，关键是它的供风量能否满足化铁工艺的要求。冲天
I plant HTD85-21 energy-efficient blower to replace the original use of 80m3 / min and 42m3 / min two parallel Roots blower, more than two years, after hundreds of furnaces production practice, and achieved satisfactory results. A comparison of two fan performance HTD85-21 energy-saving blower can replace Roots blower for 5t / h cupola, the key is whether it can meet the iron supply for the iron process requirements. soaring
