Abstract: The invention relates to a method for thermal digestion of pumpable biomass, like sewage sludge. The method comprises the steps of supplying fresh biomass, preheating the supplied fresh biomass, hydrolysing the preheated biomass, cooling the hydrolysed biomass and discharging the cooled biomass. The supplied biomass is preheated here in at least two steps, wherein in one of the steps at least a part of the supplied biomass is mixed with at least a part of the hydrolysed biomass, and wherein in another step at least a part of the supplied biomass is brought into head-exchanging contact with a prewarming or preheating medium. At least 25 percent, more preferably at least 75 percent and most preferably substantially 100 percent of the hydrolysed biomass may be mixed with the supplied fresh biomass. The mixture formed during the preheating can optionally be separated again into preheated, fresh biomass and partially cooled, hydrolysed biomass. The invention further relates to a installation for performing this method.
