| Abstract: | Directing against the problems of smaller cross-area in primary air duct of supercritical 600 MW unit no.1 in one power plant,the said problem is easily resulting in stall of the primary air fan,and coal blockage in the coal pulverizer due to unsmooth air flow sending from the primary air fan under full-load operation of the unit,the control strategy of primary air flowing in the coal pulverizer has been revised,adjusted,and optimized,and good effectiveness being obtained,making the unit can be safe and sta... |
