[QUOTE="mellotango, post: 6323147, member: 366734"] To be honest, I am not a qualified engineer but I am interested to conceptualize a energy recovery system for high pressure waste flue gas. And using a simple gas turbine technology. Diagram A would be common gas turbine systems in use where the combusted gas is directly forced onto the turbine impellers, which in turn generates electrical power. In my case, I do not want polluted flue gas to directly contact the impellers as this would greatly shorten its lifespan. Hence, I want to reposition the turbine at the said position in diagram B, and use venturi method to instead, suck in clean air, to drive the turbine. But my broad question is, is there anyway I can output the same amount of electrical power I would have normally obtained from A? By laws of physics, I see that energy is always conserved but can be changed from one form to another. i.e. same amount of injected compressed air/flue gas for A and B. So there is no reason why we cannot generate the same amount of power from scenario B, unless there is undetected energy loss somewhere, and we can think of a way to recover that back. [/QUOTE]
