    摘要： A process for improving low quality coal is disclosed, comprising subjecting a crushed low quality coal to a press treatment and a heat treatment. The process of the invention permits the production of improved coal from low quality coal, said improved coal having a high mechanical strength and a high density, and so forth, which realize the ease of handling in storage and transportation without a danger of spontaneous combustion.

    摘要： The invention relates to a method, a press, and a control device for reducing the capillary-bound water content in fiber cells of carbon-containing, finely comminuted solid materials and/or sludges. The method according to the invention includes rapidly raising the movable press plate of a filter press while the pressure chamber remains closed. A steam-coal dust mixture is formed due to the rapid expansion. At the same time, a first discharge lock is opened while the second discharge lock remains closed so that the exhaust steam flows in the direction of the controlled outlet valve. The exhaust steam can then be sent to a heat exchanger and then to another heat exchanger and, finally, may be reused for a subsequent operating cycle.

    摘要： In a device for the dewatering of naturally moist lump peat in natural obtained state and without flocculation agent through pressing, to obtain a natural composition, in terms of particles, of the dewatered product it is proposed that a system is integrated into the device, which has means (1,2,3,4,5) for the collection of the fluid pressed out via screens (31,32) and of the used water for the cleaning of the screens at their points of accumulation, for the static filtering (6,7) of the collected suspension, for the mixing together (30) of the fraction, separated there and condensed, with the fresh material which is to be treated and pressed by the device (34), for the guidance (11) of a portion of the filtrate separated there, essentially of a particle-free water, for the cleaning (12) of the screens (31,32) and for the removal (10) out of the device of a surplus portion of the separated filtrate exceeding the requirement of this cleaning.
