The EFGT (Externally Fired Gas Turbine) version of the AE-T100, also called "AE-T100E" is a system that derives from a partly completed standard AE-T100 by replacing the combustion chamber with a special piping assembly that enables the connection with a high temperature heat exchanger, installed inside the external boiler(*).
The system has been designed to combine all the advantages of a micro gas turbine with the opportunity to exploit different energy sources as, for instance, biomass burner or solar concentrator.
The use of an external boiler allows to obtain the thermal energy required to operate the gas turbine from the combustion of different sources of biomass (wood, forest waste, animal manure, sewage sludge, etc.)
The final system is therefore essentially composed by an external boiler(*) that uses a high-temperature heat exchanger(*) to transfer the thermal energy to a micro gas turbine, that operates in an open "Brayton" cycle.
Due to the split-up between combustion and evolving fluid (air), this system allows the use of solid fuels/waste fuels otherwise not usable in small size plants based on gas turbines.
The low maintenance requirements of the AE-T100E, with service intervals of 6,000 operating hours, makes this power generation system extremely attractive and competitive when compared to more conventional solutions.
Each AE-T100E configuration can be delivered in specific layouts for indoor or outdoor installation. Both layouts meet current regulations limits for noise and emissions.
All AE-T100 can be remotely monitored, controlled and operated.
