Abstract

The subject of the invention is a device for producing energy from biomass, comprising: - a first run of shafts (24) to which there are connected a compressor (26) and a first turbine (28); a first exchanger (30) performing heat exchange between, on the one hand, a fluid known as a motive fluid compressed beforehand by the said compressor (26) and expanded in the said first turbine (28), and, on the other hand, hot gases from the combustion of the biomass; a second run of shafts (32) to which there are connected a second turbine (34) and means (36) of converting kinetic energy into another form of energy; a second exchanger (38) performing heat exchange between, on the one hand, a motive fluid powering the second turbine (34), and, on the other hand, hot gases from the combustion of the biomass, characterized in that: the motive fluid used in the said second turbine (34) is the motive fluid leaving the compressor (26) without passing through the first turbine (28).

• F02C 1/04 - Gas-turbine plants characterised by the use of hot gases or unheated pressurised gases, as the working fluid the working fluid being heated indirectly
• F02C 1/06 - Gas-turbine plants characterised by the use of hot gases or unheated pressurised gases, as the working fluid the working fluid being heated indirectly characterised by the type or source of heat, e.g. using nuclear or solar energy using reheated exhaust gas
• F02C 3/20 - Gas-turbine plants characterised by the use of combustion products as the working fluid using a special fuel, oxidant, or dilution fluid to generate the combustion products
• F02C 1/05 - Gas-turbine plants characterised by the use of hot gases or unheated pressurised gases, as the working fluid the working fluid being heated indirectly characterised by the type or source of heat, e.g. using nuclear or solar energy
