Ash Removal Pulverizer Coal Furnace

Coal for pulverized coal injection in blast furnace Oct 04 2018018332An ash content of less than 10 is normally desired since i high levels of coal mineral matter can reduce the performance of pulverizer performance and throughput and increase wear in the pulverizer and conveying pipelines ii there are lower slag volumes and hence there is a better thermal efficiency iii less energy is needed to melt
