摘要
对某电厂5号锅炉送风机和一次风机失速问题进行了分析。通过试验和检查,发现造成送风机失速的主要原因是风机出口导叶安装反向;造成一次风机失速的主要原因是磨煤机通风阻力过大和出口温度过高。改进后,送风机和一次风机未发生过失速。
The stall of a forced draft fan and a primary air fan for boiler no. 2 in one power plant has been analysed. Through test and inspection, it was found that the main cause leading to stall of the forced draft fan is reversely installed the outlet guide blades, and that leading to stall of the primary air fan is most higher ventilation resistance and most higher outlet temperature of the coal pulverizer. After retrofitting, no stall appears again on the said forced draft fan and the primary air fan.
