Electric power is produced in an electric power generating combustion turbine using a biogas as fuel thereto, where a biogas, leaving a biomass gasification system at an elevated temperature of 650°-875°C. and containing tars, is partially cooled by injection of a spray of water thereto to a lower temperature of about 260°-555°but above that which would condense tars. The partially cooled biogas stream is then filtered to remove solid particulate matter therefrom and is directly charged as fuel to the electric power producing combustion turbine for the production of electric power.

A process for the production of electric power with a biogas used as a fuel for an electric power producing combustion turbine which drives a generator, which turbine will accept such a biogas only at a temperature below a predetermined temperature, wherein a biomass is gasified to produce a hot stream of a biogas, said biogas being at temperatures of between about 650°-875°C. and containing vaporized tar components and solid particulate matter, characterized in that: said hot stream of biogas, consisting essentially of a biogas, vaporized tars and solid particulate matter, has water injected thereto to partially cool the biogas to a temperature below said predetermined temperature by vaporization of said water, but above a temperature at which said vaporized tars in said biogas would condense out of said stream; filtering said partially cooled biogas to remove said particulate matter; and directly charging said partially cooled, filtered biogas containing said vaporized water and vaporized tars to an electric power producing combustion turbine to produce electric power.
