coal ash properties impact on clinker quality dear ted is there any good impact when we use lignite as a fuel instead of other solid fuels with low ash content as i have seen on net that flyash from lignite gives lime in the range of 20 if it is 20 than this flyash can be used as a source of lime in raw mix please explain me in detail ....
Coal-derived coke was the fuel used in most static kilns and so was the dominant fuel in the cement industry in the nineteenth century Coal could not be used in static kilns in which the fuel is fed in with the raw material, mainly because, during the gradual heat-up of the charge, the fuel s volatiles are lost without ignition, so wasting up ....
