    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.
