| Abstract: | In recent years,due to the tension in coal supply,the grade of as-received coal in Shengli Power Plant was descended;the sundries in raw coal were increased.The direct firing pulverizing system of 1025t/h boiler in the Plant was often blocked,and this caused the combustion instability and the increasing of combustible matter in fly ash.The blockage reason of the direct-fired system was analyzed in this paper,and an improvement scheme was determined and implemented.The safe,stable and economical operation of... |
