摘要
Water content which is bound by capillarity in fiber cells of carboniferous materials is reduced by a thermomechanical dewatering process. In the process, the carboniferous materials are conveyed by a dispersion box into a pressure chamber including upper and lower plates. Steam is applied to the materials introduced into the pressure chamber from both the upper and lower plates to heat the materials up to about 125° C. and to release the water which is bound by capillarity in the fiber cells. Initially, the pressure within the chamber is maintained at no greater than the steam pressure. Subsequently, the pressure chamber is sealed gastight and the carboniferous materials in the pressure chamber are pressed using the upper and lower plates.
