Title: Method for producing electric energy and device for carrying out this method
Inventor: ANKERSMIT JAN
IPC: F02C3/14
Filed: 1991-02-01
Abstract: The initial fuel led with the use of the inlet pipe (18) is being undertaken to the reaction in the reactor (7) and a convertible fuel, having a higher caloric value, is created as a result of this reaction. The reactor (7) heating is provided based on the indirect heat exchange, when utilising combustion gas created as a result of this combustion process. The combustion is provided in two stages. Hot combustion gas created in the first stage closed to the first combustion chamber (5) and containing a high excess of air, is guided to the second combustion stage together with the rest fuel, to the second stage with the second combustion chamber (6), however this gas is transferring a part of its pressure to the driving turbine (2) closed to the compressor (3a, 3b) used for the compressing of combustion air, before. A part of mechanical energy gained based on fuel combustion is being utilised via the partial transfer of pressure created based on gas created in the first stage to the driving gas turbine (2) closed to the compressor (3a, 3b) through which at least the rest part of pre-compressed combustion air is guided. Hot combustion gas created in the second stage is guided to the next turbine (1), where energy, via pressure lowering, is being transferred and this energy can be applied for another purposes.
