Abstract: A gas turbine engine that can operate at a very high efficiency over a wide range of load conditions. In one important feature of the invention, combustion gases are discharged along two paths, one with constant energy and the other with energy that varies in accordance with the engine load. The constant energy discharge drives a turbine that, in turn, operates a compressor for the engine at a constant, high efficiency. Alternatively, the compressor is driven at a speed that varies inversely with the engine load such that the engine operates at a high efficiency for all loads. In another, independent feature of the invention, the combustion occurs at a stoichiometric ration of fuel and air, with the turbine blades being protected from the vastly increased combustion gas temperatures by an internal array of passageways through which cooling liquid, e.g., liquid fuel, and air are channeled.

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.
