Abstract
An Advanced Cheng Combined Cycle engine is a combination of the Cheng Cycle or the Advanced Cheng Cycle and a combined cycle, and serves to further enhance the power generation capability of either the Cheng Cycle, the Advanced Cheng Cycle, or the combined cycle alone. A gas turbine is provided, having a turbine generating power, a compressor receiving power from the turbine, and a combustion chamber to which is input compressed air from the compressor along with fuel and combustion products for producing energy to drive the turbine, the gas turbine producing a hot stream gas. A heat recovery steam generator receives hot stream gas produced by the gas turbine and generates high-pressure steam therefrom. A steam turbine receives and is driven by high-pressure steam generated by the heat recovery steam generator. The steam turbine bleeds intermediate-pressure steam for cooling the turbine and for injection back into the combustion chamber of the gas turbine. A control valve throttles down high-pressure steam generated by the heat recovery steam generator to a low-pressure steam for injection back into the combustion chamber of the gas turbine.
