DEVICE FOR THERMOCHEMICAL HARMONISATION AND GASIFICATION OF WET BIOMASS AND ITS APPLICATION

摘要

FIELD: process engineering.;SUBSTANCE: invention relates to production of power carrier and/or stock carrier from water-containing and/or dry biomass. Invention covers the device for thermochemical carbonation and gasification of wet biomass and its application. This device comprises carbonation heated reactor wherein biomass is converted into solid, liquid or gaseous power carrier and/or stock carrier. Converted biomass is directed via closing outlet into cooling tank for temporary store of power carrier and/or stock carrier, said tank being connected with carbonation reactor. Cooling tank is connected with gasification heated reactor wherein gas and wastes like ash are separated from power carrier. Carbonation reactor is enclosed in heating jacket for feed of heat power and extra heat power from gasification reactor. Energy of cooling from cooling tank is fed to gasification reactor cooling jacket. Water is fed to cooling reactor to allow a continuous working cycle. Reaction gas is fed from carbonation reactor and/or cooling tank into gas store vessel.;EFFECT: production of all carbon from biomass gases, ruled out critical reaction products as gases and evaporation via combustion in gasification reaction.;12 cl, 4 dwg, 2 tbl
