<p>Method of recovering energy from waste liquors from pulp processes, wherein the waste liquor is burned in a waste liquor recovery boiler and energy is recovered from the flue gases, which are formed by producing saturated or partially superheated steam in the recovery boiler. According to the invention, a portion of the waste liquor is pressure heat treated to release gases and/or treated in a liquid phase in a pressurized process for converting the waste liquor into a fraction containing an oleaginous fuel and a fraction containing inorganic components. The waste liquor is thereby treated for instance in a hydrogenation process. The waste liquor from the pressure heat treatment and/or the waste liquor fraction containing inorganic components is burned in the recovery boiler. The released gases and/or the fraction containing oleaginous fuel is burned in a separate superheating boiler, in which the steam produced in the recovery boiler is superheated.</p> |
