Patent ID: 6871603

Claim:
A gasification system for producing useful energy from a source of biomass material, the gasification system comprising: a gasifier for partially combusting biomass material into gaseous fuel; a contained fuel preparation site for preparing biomass material to be delivered to the gasifier from a source of biomass material, the site including a dryer for drying the biomass material to optimise moisture content of the biomass material; a boiler for combusting gaseous fuel from the gasifier to produce useful energy; an air delivery system for directing combustion air to at least one of the gasifier and the boiler from the contained fuel preparation site, the air delivery system being arranged to draw at least some of the combustion air directly from an exhaust of the dryer before feeding the air to said at least one of the gasifier and the boiler; and an induced draft fan in communication with boiler exhaust for maintaining the boiler and gasifier at a negative pressure in relation to atmosphere.
