Experimental Studies On Steam Pressure Filtration Of Coal Concentrate Filter Cakes

Steam pressure filtration combines mechanical and thermal processes in one filtration device. Steam condensation at the cold layers of the filter cake, build a condensation front, which even removes the capillary water from the porous filter cake. Depending on the choice of parameters it is possible to achieve a very low residual moisture content. The influence of the parameters on the dewatering results was systematically examined on a bench-scale apparatus. This paper explains the physical fundamentals, the influence of the cake dewatering parameters, and one possible method of applying the process to a disk filter device as well.
