METHOD OF PRODUCING ENERGY AT A PULP MILL

摘要

A method to produce energy at a pulp mill, including the steps of: combustin g pulping process waste liquor in the furnace of a recovery boiler to generate flue gases, recovering heat from the flue gases by producing saturated and/o r partially superheated steam in the recovery boiler, gasifying wood, bark or wood wastes in a gasifier for producing a combustible gas, burning at least part of the combustible gas in a superheating boiler, and superheating the saturated and partially superheated steam in the superheating boiler to produce superheated steam.
