Pyrolysis plant and method for thermal mineralization of biomass and production of combustible gases, liquids and biochar

Abstract

A pyrolysis plant (2) comprising a reactor (3) for producing pyrolysis gas (28) from biomass (30), wherein the reactor (3) comprises at least one reaction channel (4) that: a) has at least one integrated heating circuit (18) configured to heat the at least one reaction channel (4) to a temperature that is high enough to gasify the biomass (30) and b) is configured to generate a flow (Q) of gasified biomass (30) that causes a portion of the gasified biomass (30) to circulate in the reaction channel (4), wherein the pyrolysis plant (2) comprises a feed section (6) configured for feeding the biomass (30) into the at least one reaction channel (4). The pyrolysis plant (2) comprises: - one or more flow sensors (9, 9’) arranged and configured to detect the flow (Q), - a control unit (12) arranged and configured to control the flow (Q) in the reaction channel (4) by regulating the velocity at which biomass (30) is feed into the into the at least one reaction channel (4), wherein the pyrolysis plant (2) is configured to be operated without using any blower (15) when the at least one reaction channel (4) has been heated to the temperature that is high enough to gasify the biomass (30).
