摘要
为降低一次风机电耗,设计并实施了一次风压自适应控制系统,通过在原有一次风压设定值的基础上,再叠加一个独立的自适应一次风压力偏置值回路,在保证制粉系统安全运行的前提下,逐步降低一次风机出口压力,达到一次风机经济运行的目的。锅炉运行一次风压的降低,可使空气预热器漏风率有所下降,引风机电耗也会相应下降,节能降耗效果明显。
To reduce the power consumption of primary air fans , an adaptive conair pressure was designed and applied by adding an independent adaptive primary air pressure bias circuitbased on the original setting value, thus gradually reducing the primary air pressure and the powerconsumption of primary air fans under the premise of ensuring the safe operation of the coal pulverizingsystem. Meanwhile both the air preheater leakage rate and the power consumdrop accordingly due to the reduction of primary air pressure,resulting in obvious energy
