摘要 |
The invention relates to the processing of biomass, particularly but not exclusively poultry litter, to generate energy. A method for generating power from biomass comprises a gasification process involving the gasification of biomass to produce a combustible fuel gas and a power generation process involving combustion of the combustible fuel gas to produce a combustion exhaust gas which is fed to a power generator to generate power and a generator exhaust gas. The method further comprises placing compressed air in thermal contact with the generator exhaust gas to facilitate heat transfer between the compressed air and the generator exhaust gas, and feeding a first portion of compressed air that has thermally contacted the generator exhaust gas to the gasification process to assist in the gasification of the biomass. An alternative method involves using the generator exhaust gas to heat the combustible fuel gas. |
