| Abstract: | By transforming the below coal tube of raw coal bunker and enhancing the pinch of roller,the grinding capacity raised 12～18 t/h.The performance of coal powder was improved by controlling the granularity,water and temperature of the coal powder.And by enhancing the pressure of nitrogen and the pressure of spray pot,playing down flux of renew gas and wide and equal injection so on,the pulverized coal injection quantity of every BF raised 2 t/h,reducing the cost of fuel. |
