Using more coal

Being a solid fuel, coal is harder to transport, store, and utilize than either liquid or gaseous fuels. Moreover, organic impurities inherent in coal provide a serious drawback to the wider use of coal. The author recommends washing more coal and accepting some additional Btu losses by in-depth cleaning to decrease impurity content. Costs and capacities of coal preparation facilities and the reduction of SO/sub 2/ and particulate emissions are briefly discussed. (CKK)
