Thermodynamic Cycles of Air Microturbine Power Plants Working on Biomass Fuels

The gas turbine engine is modified to work as an air turbine set which consists, in the simplest arrangement, of a compressor, a heat exchanger and a turbine. Air is a working medium for both: the compressor and the turbine. This kind of air turbine set can be applied in power plants working on biomass fuels. In this solution we can burn fuels of varying parameters in the external combustion chamber without any harmful effects on the operation of the air turbine set. The analysis was carried out for different thermodynamic cycles of power plants with air turbines. The variants with regenerators and different cogeneration systems were considered.
