Abstract:
The work presented in this paper is based on the EU FP6 project “Innovative small-scale polygeneration system combining biomass and natural gas in a micro gas turbine (BIO-MGT)”, which aims on the development of a small-scale biomass CHP technology based on an externally with biomass and internally with natural gas fired micro gas turbine (MGT) with a nominal electric capacity of about 100 kWel, where the MGT exhaust gas should be used as efficiently as possible and the biomass contribution should be as high as possible (target: > 50% based on NCV). This new technology aims to close the gap in the power range between 70 and 200 kWel, in which no biomass CHP technology is currently available (i.e. the gap between the Stirling engine (< 70 kWel) and the ORC (> 200 kWel) technology). The development of a system which complies with these requirements took place. A new biomass furnace technology was developed for the complete and exclusive utilisation of turbine exhaust gas as oxidising agent for combustion. A high temperature heat exchanger was designed to transfer heat from the flue gas of the biomass furnace to the pressurised air of the MGT cycle. The plant was started up in January 2010. First operating experiences could already be gained. Test runs at various loads are scheduled for the next half year.
