Because of 150 MW unit in Datang Hancheng Power Plant commonly operating under low load

hence

adopting optimized operating mode of auxiliary machines for said boiler

such as stopping pulverized coal exhauster providing with primary air

stopping heating facility of ash hopper for the electrostatic precipitator(EP) in summer season

stopping rear electric field of EP

and operating of only one single induced draft fan etc.

has remarkable electricity-saving effectiveness

and basically doesn’t affect the boiler efficiency. The optimized jointly operation mode of auxiliary machines for a boiler is a betler means for electricity-saving in low load operation of the peak-regulating units.
