Abstract:
EFGT (Externally Fired Gas Turbine) are convenient to use solid biomass on site with few or no pretreatment and spare life of turbine working only with clean air. It is therefore a promising technology for smallscale distributed CHP, up to about one electrical megawatt. Moreover, expected electrical efficiency, strongly dependent on turbine inlet temperature, may reach values over 0,20-0,25, which is a quite high value compared to other biomass-based CHP technologies in this range of power. However EFGT remain at an early stage of development. Indeed, the high temperature heat exchanger must increase the temperature of air up to more than 1000 °C to remain electrically efficient. Reaching such temperature represents therefore a great challenge and requires advances on material. Moreover, fouling by biomass combustion gases is also a serious issue which has to be taken into account.
