ABSTRACT:
A hybrid biomass natural gas/oil power generator system includes a circulating fluidized bed boiler which burns, for example, wood chips, a combustion turbine driven mainly by natural gas and a steam turbine. The wood chip boiler has its hot flue gas utilized to provide both steam, hot water and hot air which is eventually used by the combustion turbine. This hot air is first humidified and then has its temperature raised to approximately the boiler temperature by passing it over or through hot solids obtained from the boiler. The filtered humid air is mixed with steam and combusted natural gas to drive the combustion turbine. Lastly the hot solids from the boiler are also used for drying the wood fed to the wood chip boiler.
