ABSTRACT:
A system for burning biomass to fuel a gas turbine 10 which generally comprises a pressurized combustion chamber 54, a feeder device 14 for feeding biomass particles into the combustion chamber 54, an air compressor 82 for supplying compressed air to the combustion chamber 54, an ash extracting device 92 for removing ash from the combustion gases 75, a turbine 116 and a central controller 126 for monitoring and controlling various aspects of the system 10. The biomass is fed into the combustion chamber 54 where the particles combust and produce highly pressurized combustion gases 75. The ash extracting device 92 removes the ash in the combustion gases 75 before the combustion gases 75 enter the turbine 116. The highly pressurized combustion gases 75 enter the turbine 116 where they expand to produce work and cause the blades of the turbine 116 to rotate. The turbine 116 drives an electric generator which is linked to a power transmission line through any suitable switching gear.
