摘要： A steam-injected free-turbine type of gas turbine is disclosed. In order to avoid the necessity of redesigning the compressor/core turbine, the shaft of the core turbine is modified to provide additional load output. As steam is injected into the system the resulting excess power of the core turbine is taken out of the system by coupling the compressor output shaft with a load. Thus, the core turbine operates as a single shaft turbine in addition to the existing power turbine. A control provides control of the load output of the two turbine output shafts so that the compressor/turbine stays in the matched operating domain.

摘要： 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.

摘要： A steam injection nozzle system for injecting steam into a combustion liner of a gas turbine for enhancing power output and efficiency of the gas turbine. The combustion liner has a plurality of dilution holes for supplying air to a combustion chamber to create turbulence. A steam manifold surrounds the combustion liner and has a plurality of steam injection nozzles, each steam injection nozzle being disposed opposite a corresponding dilution hole, without touching the combustion liner, for injecting the steam directly into the combustion liner through the dilution holes. The steam is injected without altering an existing amount of air through the plurality of dilution holes, resulting in a constant amount of air through the plurality of dilution holes independent of the amount of steam injected therein within a predetermined range of steam. The predetermined range of steam injected may be between approximately 9% and approximately 35%, inclusive, of the air flowing through the combustion liner. Alternatively, the predetermined range of steam injected may be less than or equal to approximately 35% of the air flowing through the combustion liner.

摘要： An improved system of transferring heat energy from a high temperature fluid to a low temperature fluid is described. A countercurrent heat exchanger is employed in which heat transfer fluids undergo one or more thermodynamic transitions at various pressures by employing conventional heat exchangers having additional components. It has been determined that by employing this system of the present invention under a critical choice of design parameters, a substantially greater amount of heat energy can be transferred per unit area of the heat exchanger than was possible by conventional techniques.
