Abstract (en)
[origin: WO2013098525A1] A co-current (14) fixed bed gasifier (14) intended to convert biomass (26) into synthesis gas and ash with the aid of a gasification agent, said gasifier (14) comprising a reactor body, said reactor body comprising an upper part (22) and a lower part (23), into which gasifier (14) the biomass (26) is introduced via an inlet duct (1) located in the top of the upper part (22) of the body (22) of the gasifier (14); the synthesis gas is evacuated via a synthesis gas evacuation duct (12), and the ash is evacuated in the bottom part of the lower part (23) of the reactor body through an ash evacuation duct (10), and said gasifier (14) comprising, from top to bottom, - a biomass (26) pyrolysis area (16), - a biomass (26) oxidation area (17), - a reduction area (18), - a grid (8) comprising a plurality of openings through which the ash passes to be evacuated, and said gasifier (14) comprising means of introducing a gasification agent, such as air or oxygen, said gasifier (14) being characterised in that said means of introducing the gasification agent comprise: a cone (13) for diffusing the gasification agent located at the top of the oxidation area (17) of the gasifier (14), or above said oxidation area (17), means of injecting (19, 29) the gasification agent located in the oxidation area (17) of the gasifier (14).
