在1975年末和1976年初,凯塞尔钢铁公司在为一个新碱性氧气转炉炼钢车间选择气体净化系统的过程中,发现许多问题都与高特性风机有关。凯塞尔公司的高特风机直径为11呎4(1/2)时,驱动电机为5500马力,1180转/分,这些风机在负压为85时水柱时,其容积流量为200000呎~3/分,叶片外缘速度>42000呎/分。对于这种高特性风机来说,重要的问题是保持风机不产生积垢,从而使风机叶轮保持平衡状态。对一些碱性氧气炼钢装置的观察表明,处理积垢问题有许多不同方法。在某些情况下,
In late 1975 and early 1976, Kessel, in selecting a gas purification system for a new BOF steelmaking plant, found many problems associated with high-profile fans. Kessel’s Giant fan diameter of 11 feet 4 (1/2), the drive motor 5500 horsepower, 1180 rev / min, these fans in the negative pressure of 85 when the water column, the volume flow of 200,000 feet to 3 / Min, blade outer edge speed> 42,000 feet / min. An important issue for this high-performance fan is keeping the fan free of fouling, keeping the fan impeller in balance. Observations of some alkaline oxygen steelmaking plants show that there are many different ways of dealing with fouling problems. In some cases,
