Abstract:
The use of micro gas turbines as part of combined heat and power (CHP) is studied at the Institute of Combustion Technology of the German Aerospace Center (DLR). Micro gas turbines are very well-suited for CHPs because they exhibit higher fuel flexibility and substantially lower pollutant emissions compared to conventional gas engines. The fuel flexibility allows the combination of the micro gas turbines with thermal gasifiers or bio gas reactors so that an efficient use of biomass in these facilities and an efficient, CO2-free and environmental friendly production of electrical energy and heat is possible. The CFD based optimization of micro gas turbine combustion chambers for these fuels requires the knowledge of validated reaction mechanisms. Therefore ignition delay times of a wood gasification and an algae fermentation product were determined in a shock tube and compared to the predictions of two reaction mechanisms. The Li et al. mechanism is proven as very well-suited for describing the combustion characteristics of both product gases at micro gas turbine typical conditions.
