Subbituminous coal and lignite, as mined, contain 20 to 40 per cent moisture, which limits their markets, due to slacking and to the costs of transporting this water. By drying these fuels with saturated steam at 400 psi pressure, by the Fleissner process, described in this paper, the free-moisture content may be lowered to 4 to 8 per cent, reducing slacking and increasing the available market. The properties of the dried fuel and processing data are presented and the construction and operating costs of plants are estimated. |
