<p>The invention relates to an updraft gasifier (4) updraft gasifier (4) for a biomass gasification system (2) to generate gasifier product gas to be burned in a combustion unit (6), which gasifier (4) comprises:
€¢ a first inlet (9) for biomass in the upper area (12) of the gasifier (4), and
€¢ a first outlet (11) for ash in the lower area (13) of the gasifier (4), and
€¢ a second inlet (14) for a gasification agent in the lower area (13) of the gasifier (4), and
€¢ a second outlet (15) for the gasifier product gas in the upper area (12) of the gasifier (4), and
€¢ a grate (16; 23) between the first inlet (9) and the first outlet (11) to handle the ash;
wherein the
€¢ grate (16; 23) is arranged in a cross-sectional area of the gasifier (4) and comprises at least one air channel (17; 25, 26, 31) connected to the second inlet (14) and at least one nozzle (20; 32) connected to the air channel (17; 25, 26, 31) to transport the gasification agent into the cross-sectional area of the gasifier (4).</p> |
