摘要:
河曲电厂一期磨煤机料位采用的是差压测量方式，机组运行期间，经常出现差压料位测量不准确、料位波动大、给煤机料位自动无法投入的情况。通过对原有料位计设备进行改造，减少故障的发生，保证了自动投入率，提高了公司节能减排效益。The first phase of Hequ power plant coal grinding machine level uses the differential pressure measurement. During the operation of the unit, the differential pressure level measurement is of-ten not accurate, the level fluctuation is major, and the coal feeder automatically disjoints situation. The transformation of the original material level meter equipment reduces the occurrence of the fault, ensures the automatic input rate, and makes contribution to the company’s energy-sav- ing emission reduction.
