Micro-CHP gas fired boiler with gas turbine assembly

摘要

A micro-CHP gas boiler comprises a heat exchanger having a combustion space surrounded by a water flowpath, and a gas turbine assembly which is installed in the combustion space. The gas turbine assembly includes a generator surrounded by an annular combustion chamber and cooled by a water jacket which forms part of the flowpath, and a fuel gas compressor which is integrated into the thrust runner on the turbine rotor shaft between foil air bearings.
