    • The invention relates to a method for thermal digestion of pumpable biomass, such as sewage sludge. The method comprises the steps of supplying fresh biomass, preheating the supplied fresh biomass, hydrolyzing the preheated biomass, cooling the hydrolyzed biomass and discharging the cooled biomass. The supplied biomass is preheated here in that at least a part of the supplied biomass is mixed with at least a part of the hydrolyzed biomass. Additionally the hydrolyzed biomass can be separated at high temperature, so substantially immediately after the hydrolysis, into a solid fraction and a liquid fraction, in particular by centrifugation. The mixture formed during the preheating can optionally be separated again into preheated, fresh biomass and partially cooled, hydrolyzed biomass. The invention further relates to an installation for performing this method.
    • 本发明涉及一种用于热泵消化可泵送的生物质如污水污泥的方法。 该方法包括供应新鲜生物质,预热所供应的新鲜生物质,水解预热生物质,冷却水解生物质和排出冷却生物质的步骤。 供应的生物质在此被预热,因为供应的生物质的至少一部分与至少一部分水解的生物质混合。 另外,水解的生物质可以在高温下基本上立即在水解之后分离成固体部分和液体部分,特别是通过离心。 在预热期间形成的混合物可以任选地再次分离成预热的新鲜生物质和部分冷却的水解生物质。 本发明还涉及用于执行该方法的设备。
