摘要： Within the process a supercharged first combustion chamber is followed by: a first turbine, a second combustion chamber, a second turbine, and a preheating heat exchanger. Primary bleed water vapor coming from the secondary process, or a mixture of the bleed water vapor and air coming from the supercharger, are preheated. Secondary-process feed water is vaporized in a waste heat boiler. The combustion gases are expanded in the second turbine to a pressure 0.5 bar lower than that of the surrounding atmospheric pressure. The remaining combustion gases are compressed by a combustion-gas supercharger to the surrounding atmospheric pressure.

摘要： Method and apparatus for achieving high efficiency in an open gas-turbine process, in which a supercharger compresses air, which is burned together with a fuel in a first combustion chamber, which is followed by a first turbine, a second combustion chamber, a second turbine, and a preheating heat exchanger, in which primary bleed water vapor coming from the secondary process, or a mixture of the aforementioned water vapor and air coming from the supercharger are preheated. From the heat exchanger the combustion gases go to a waste-heat boiler, in which the secondary-process feed water is vaporized. The combustion gases are expanded in the second turbine to a pressure 0.5 bar lower than that of the surrounding atmospheric pressure. The remaining combustion gases are compressed by a combustion-gas supercharger to the surrounding atmospheric pressure. After the low-pressure turbine the water vapor is condensed in a condenser into water, which is compressed by a pump to a maximum pressure and is preheated and vaporized in the waste-heat boiler. After the waste-heat boiler the water vapor goes to a combined high/medium-pressure turbine, from which a secondary-process primary bleed is taken, which is injected into the gas-turbine process after the preheating heat exchange after the supercharger and/or at the latest to the start of the blades of the first turbine.

摘要： A method and apparatus for improving the energy efficiency of an existing gas turbine combined cycle plant, which includes a gas turbine having a compressor that pressurizes combustion air which is combusted with fuel in a combustion chamber to form combustion gases. The compressor is followed by a turbine, a high temperature heat exchanger, a low temperature heat exchanger, and a secondary process steam turbine II. Water from the secondary process steam turbine II is condensed in a following condenser-heat exchanger, pressurized by a following pump, and then is vaporized.

摘要： Method and apparatus for improving the energy efficiency of existing gas turbine combined cycle plants in which a compressor pressurises air which is combusted with fuel in a combustion chamber, followed by a turbine and a high temperature heat exchanger and a low temperature heat exchanger. In the secondary circulation after the steam turbine II, steam is condensed in the condenser into water, which is pressurised to the maximum pressure by means of a pump and preheated in low temperature heat exchanger and vaporised in a high temperature heat exchanger. After the high temperature heat exchanger, steam enters the steam turbine wherefrom a tap is taken, if necessary, which is injected after preheating into the combustion chamber of the gas turbine process or at the latest the beginning of the vanes of the turbine. Before steam turbine II, the enthalpy of steam (and additional water) at below 1 atm is increased by means of the condensation heat of the water contained in the combustion gases, after which intermediate superheating is applied to the saturated Rankine circulation steam using the excess heat of the low temperature heat exchanger.
