摘要： The present invention is a combined cycle power plant design increasing output and efficiency of heavily-fired combined cycle plants operating below the maximum output point by allowing the steam temperature to increase as the amount of duct firing is reduced. The cycle design also reduces the installed cost of the overall plant. Making steam temperature a variable in operating the power plant meets the problem of actual operation distancing itself from Carnot efficiency in reduced load or part load conditions.

摘要： A method and arrangement for supplying a waste heat exchanger with exhaust gas from a gas turbine are provided. The exhaust gas is guided through a diverter having a pivotable butterfly valve. When the valve is opened for initial entry of gas into the exchanger, the gas flows about the free edge of the valve. At least during initial entry of gas into the exchanger, the stream of gas is at least partially deflected downstream of the butterfly valve. This deflection is preferably eliminated after the initial entry of gas into the exchanger.

摘要： Apparatus for generating power includes a gas turbine unit having a compressor for compressing ambient air and producing compressed air, a combustion chamber to which the compressed air is supplied, a source of relatively high grade fuel for burning in the combustion chamber and producing combustion gases, and a gas turbine connected to generator and to the compressor for expanding the combustion gases and producing exhaust gases. The apparatus further includes a combustor that burns relatively low grade fuel, and produces combustion products, and an indirect contact heat exchanger responsive to the combustion products for heating the compressed air before the latter is applied to the combustion chamber, and for producing cooled combustion products. In addition, an energy converter is provided having an organic working fluid responsive to the exhaust gases for converting heat in the exhaust gases to electricity. Finally, the apparatus of the invention serves to minimize the consumption of high grade fuel in the presence of changes in the heating value of the low grade fuel.

摘要： Provided is turbine plant using methanol as fuel in which working fluid is compressed by compressor 1 and led into combustor 2. A mixture of H2 and CO2 as fuel added with O2 is burned to generate high temperature gas, which works at high temperature turbine 3, flows through heat exchangers 4, 5 and returns partly to the compressor 1 and enters partly low pressure turbine 7 of bottoming system to work. Condensed water from condenser 9 of the bottoming system is pressurized by pressure pump 10 and flows through the heat exchangers 4, 5 to become high temperature steam and to work at high pressure turbine 6. Exhaust gas thereof is mixed into the combustor 2. A mixture of methanol and water is supplied into reformer 13 to absorb heat from the heat exchanger 4 to be reformed into H2 and CO2, which is supplied into the combustor 2. A high temperature portion of the high temperature turbine 3 is cooled by cooling medium extracted from compressor 1 outlet and high pressure turbine 6 outlet thereby reliability of the high temperature turbine 3 is enhanced.

摘要： A gas and steam-turbine plant includes a heat-recovery steam generator which is connected downstream of a gas turbine on the flue-gas side and has heating surfaces connected in a water/steam circuit of a steam turbine. A gasifier is connected upstream of a combustion chamber of the gas turbine for integrated gasification of a fossil fuel. Oxygen can be fed to the gasifier from an air-separation unit, to which in turn a partial flow of air compressed in an air compressor associated with the gas turbine can be admitted on the inlet side. In such a gas and steam-turbine plant, reliable cooling of the bleed air, in an especially simple type of construction, is to be ensured in all operating states, irrespective of the integration concept which is taken as a basis. Therefore, a heat exchanger for cooling the partial flow of compressed air is connected on the primary side in a bleed-air line connecting the air compressor to the air-separation unit. The heat exchanger is constructed on the secondary side as an evaporator for a flow medium.

摘要： A process for increasing the specific output of a combined cycle power plant and providing flexibility in the power plant rating, both without a commensurate increase in the plant heat rate, is disclosed. The present invention demonstrates that the process of upgrading thermal efficiencies of combined cycles can often be accomplished through the strategic use of additional fuel and/or heat input. In particular, gas turbines that exhaust into HRSGs, can be supplemental fired to obtain much higher steam turbine outputs and greater overall plant ratings, but without a penalty on efficiency. This method by and large defines a high efficiency combined cycle power plant that is predominantly a Rankine (bottoming) cycle. Exemplary embodiments of the present invention include a load driven by a topping cycle engine, powered by a topping cycle fluid which exhausts into a heat recovery device.

摘要： A combined cycle power plant having a gas turbine plant and a steam turbine plant combined together is disclosed. Steam is used for cooling a high-temperature portion (5) to be cooled around the combustor (4) of the gas turbine (2). The power plant has an air duct (9), connected to a steam path (7) for supplying steam for cooling the high-temperature portion (5), for cooling this portion using air if the steam for cooling is insufficient, typically when the plant is activated or stopped, and the air duct includes a device for boosting the air to have a pressure higher than that inside a combustor (4) of the power plant. Accordingly, the combustor and attached piping arrangement can be protected from burning and the power plant can be safely and reliably operated for a long time.

摘要： In a gas and steam turbine plant with a waste-heat steam generator, a fuel gasification device is located upstream of the combustion chamber of the gas turbine via a fuel line. The after-heat steam generator is located downstream of the gas turbine on the flue-gas side and the heating surfaces of which are connected into the water/steam circuit of the steam turbine for the integrated gasification of a fossil fuel. For especially high plant efficiency, a heat exchanger is connected on the primary side into the fuel line between the gasification device and a saturator. In addition to a mixing device for admixing nitrogen, the heat exchanger likewise is connected on the secondary side into the fuel line between the saturator and the combustion chamber.
