The invention relates to a process for the combined generation of electrical and mechanical energy from the oxidation of fuel, whereby a gas containing hydrogen is generated by the endothermal reaction of hydrocarbon compounds, a part of said gas is burned to provide a combustion gas, a gas containing oxygen is compressed and introduced into the burning stage and the energy from the expansion of the hot combustion gas is generated in at least one gas turbine. In addition, the combustion gas produced is used to heat the endothermal reaction indirectly. According to the invention, at least part of the hydrogen-containing gas produced to generate electrical energy is taken as the anode gas via a fuel cell system and the anode exhaust gas is used to generate the combustion gas.

Un procédé permet de générer en même temps de l'énergie électrique et de l'énergie mécanique par oxydation d'un combustible, générant un gaz contenant du H2 par réaction endothermique de composés hydrocarbures. Une partie du gaz contenant du H2 est brûlée afin de générer un gaz de combustion, un gaz contenant du O2 est comprimé et introduit dans l'étage de combustion et l'énergie est générée par la détente du gaz chaud de combustion dans au moins une turbine à gaz. En outre, le gaz de combustion détendu est utilisé pour chauffer indirectement la réaction endothermique. Selon l'invention, au moins une partie du gaz contenant du H2 ainsi généré est conduit en tant que gaz anodique, à travers un système de cellules de combustible afin de générer de l'énergie électrique, et les gaz anodiques de fumée sont utilisés pour générer le gaz de combustion.

An installation for generating energy comprises a compressor assembly for compressing air, having a low-pressure compressor, which is connected to a high-pressure compressor via a primary air path. Furthermore, a compressor turbine assembly is provided for the purpose of driving the low-pressure compressor and/or the high-pressure compressor. The installation also has a combustion device for burning a suitable mixture of compressed air and a fuel, and a power turbine with a rotatable shaft for releasing mechanical energy. An exhaust-gas pipe system is connected to the exhaust-gas outlet of the power turbine. The installation comprises a secondary air path which, at an inlet end thereof, is connected between the outlet of the low-pressure compressor and the inlet of the high-pressure compressor, in such a manner that, of the compressed air originating from the outlet of the low-pressure compressor, a primary airflow passes via the primary air path to the high-pressure compressor and a secondary airflow passes into the secondary air path. At the secondary air path, first water injection means are provided for injecting water into the secondary airflow. The secondary air path is connected, at an outlet end thereof, to the connection between the outlet of the compressor turbine assembly and the inlet of the power turbine.
