A downdraft gasifier for producing a gaseous fuel to be used in an engine from a carbonaceous material with a pyrolysis module, a reactor module, and a heat exchanger system that cooperate to produce the gaseous fuel from the carbonaceous material and to extract particulates from the gaseous fuel from the reactor. The heat exchange system includes a first heat exchanger coupled to the dryer module that heats the carbonaceous material with the gaseous fuel output of the reactor module to dry the carbonaceous material; a second heat exchanger coupled to the pyrolysis module that heats the dried carbonaceous material with the exhaust from the engine to pyrolyze the dried carbonaceous material into tar gas and charcoal; and a third heat exchanger coupled to the reactor module that heats air used to combust the tar gas with the gaseous fuel output of the reactor module to preheat the air. |
