Abstract

the Temperature difference in the combustion chamber and the exhaust outlet in aircraft engines and gas turbines in power stations, can make us to install thermoelectric generators with optimal design to produce the largest electrical energy as possible and reduce thermal resistance of heat transfer as possible to protect the walls of the combustion chamber from damage, select suitable thermoelectric materials with efficiency as high as possible and has high temperature limit, this Temperature difference with thermoelectric generators lead to generate electricity and also to improve efficiency, reduce pollution and decrease fuel consumption.

Claims

AMENDED CLAIMS
received by the International Bureau on 19 October 2014 (19.10.2014)
2. Improving the efficiency of gas turbines and jet engines, comprising:
The design and arrangement of thermoelectric generators inside the zones for the combustion chamber (annular, Cannular, etc.) for gas turbine and jet engine.
3. A system according to claim 2, wherein the thermoelectric generators between the exterior area of Intermediate zone for any combustion chamber and the coolant air to prevent the damage for the combustion chamber.
4 A system according to claim 2, wherein the thermoelectric generators between the exterior area of Dilution zone for any combustion chamber and the coolant air to prevent the damage for the combustion chamber.
5. A system according to claim 2, wherein the thermoelectric generators between the exterior area of Primary zone for any combustion chamber and the coolant air to prevent the damage for the combustion chamber.
6 A system according to claim 2, wherein there is a possibility of adding thermoelectric generators as proposed in claims 3, 4, and 5 to any heat recovery systems use thermoelectric generators on (exterior of the turbine section, exhaust section and the nozzle section etc.). This contributes to more improvements in the efficiency.
7. A method for generating electricity from thermoelectric device and efficiency improvement, comprising:
