Design of ethanol micro gas turbine engine

To develop the application of the biomass fuel in micro-turbine-based distributed energy system, micro gas turbine using ethanol as fuel was designed. The design operation parameters of this micro gas turbine were determined by thermodynamic cycle. Based on the parameters and the characteristic of ethanol fuel, the combustor geometry size was designed. Thus the technology of micro gas turbine combustor was achieved for the combustion of ethanol fuel. Experimental results of this engine indicate that the ethanol micro gas turbine engine has successfully realized self-operating, and it demonstrates the designed scheme of the engine is feasible.
