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 supplementally 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 steam generator has a combustion chamber which is configured for an approximately horizontal main direction of flow of the fuel gas and which is followed on the fuel-gas side, via a horizontal gas flue, by a vertical gas flue. The containment walls of the combustion chamber are formed from evaporator tubes. Temperature differences between adjacent evaporator tubes of the combustion chamber are to be kept particularly low in all the load states of the steam generator. For this purpose, a first group and a second group of evaporator tubes can be acted upon in each case in parallel by a flow medium. The first group of evaporator tubes is connected in series with the second group.

摘要： A semi-closed combined cycle power system 100 is provided which can also convert an open combined cycle gas turbine 10 into a non-polluting zero emissions power system. The prior art open combined cycle gas turbine 10 includes a compressor 20 which compresses air Anull and combusts the air Anull with a fuel, such as natural gas. The products of combustion and the remaining portions of the air form the exhaust Enull which is expanded through the turbine 40. The turbine 40 drives the compressor 20 and outputs power. The exhaust Enull exits the turbine 40 and then can optionally be routed through a heat recovery steam generator 50 to function as a combined cycle. According to this invention, the exhaust Enull is not emitted into the atmosphere, but rather is routed to a divider 110. The divider 110 includes two outlets for the exhaust Enull including a return duct 120 and a separation duct 130 which both receive a portion of the exhaust Enull. The return duct 120 routes a portion of the exhaust Enull back to the compressor 20. Before reaching the compressor 20, an oxygen duct 150 adds additional oxygen to the exhaust Enull to form a gas mixture C which includes CO2 and steam from the exhaust Enull and oxygen from the oxygen duct 150. This gas mixture C has characteristics which mimic those of air, so that the compressor 20 need not be modified to effectively compress the gas mixture C. The gas mixture C is compressed within the compressor 20 and routed to the combustor 30 where the fuel combusts with the oxygen of the gas mixture Cnull and produces exhaust Enull which is substantially entirely CO2 and steam. This exhaust Enull is routed through the turbine 40 and expanded to drive the compressor 20 and output power. The exhaust Enull exits the turbine 40 and is routed back to the divider 110, preferably by way of a heat recovery steam generator 50 or other heat removal device, so that the semi-closed cycle operates as a combined cycle power system 100. The divider 110 directs a portion of the exhaust Enull to a separation duct 130 which leads to a condenser 140. In the condenser 140 the exhaust Enull is separated by condensation of the steam/water portion of the exhaust and removal of the remaining CO2 as gas from the condenser 140. The only exhaust from the semi-closed power system 100 is water and CO2 from the condenser. The CO2 exhaust is substantially pure and ready for appropriate further handling and disposal. Hence, no pollutants are emitted from the semi-closed power system 100. The return duct 120 can include a partial condenser 210 to condense a portion of the steam within the exhaust Enull. This condensed steam is then routed back through the heat recovery steam generator 50, where it is converted to steam. This steam can be injected through a steam injection port 233 directly into the combustor 30 to enhance the power output and efficiency of a steam injection power system 200 variation of this invention.

摘要： A combined cycle power plant is disclosed, whose target high-temperature portion in the gas turbine can be reliably and sufficiently cooled, and in which the heat generated via the cooling can be reliably recovered, thereby improving the efficiency. Here, the exhaust gas from the high-pressure turbine is introduced as cool steam to the steam cooling system for cooling the target high-temperature portion in the gas turbine. This cooling process is efficiently and suitably performed by using the characteristic of the above high-pressure exhaust gas relating to quantity, pressure, or temperature.

摘要： The present invention provides an air-heated/hot-water vaporizer having a very high thermal efficiency and which is easy to handle for a long period of time. Hot water supplied to the inner tube 24 of the hot water tube 22 passes through the inner tube 24 and flows out from the other end thereof to the closed end side of the outer tube 23. The hot water having flowed out to the closed end side of the outer tube 23 passes through the annular path formed by the inner tube and the outer tube 23, flows in a direction counter to that of the hot water flowing in the inner tube 24, and flows from the opening of the outer tube 23 to the outside. Liquefied gas supplied to the liquefied gas tube 21 flows along the outside of the outer tube 23, and is heated and vaporized by hot water flowing through the hot water tube 22.

摘要： One heat engine includes a hydro-electric turbine, a steam source configurable to generate steam from a hot water source, a condenser, and a slug intake bend in a first pipe coupled between the steam source and the condenser. The slug intake bend is configurable to receive a slug of water from a cold water source. The steam from the hot water source pushes the slug of water up a vertical distance to the condenser. The condenser is configurable to receive the slug of water and the steam and provide liquid water from the slug of water and steam to power the hydro-electric turbine.

摘要： This invention relates to steam generators, and more particularly to horizontal steam generators for nuclear power plants with a water-water energetic reactor (VVER). We claim a horizontal nuclear power plant steam generator comprising a cylindrical vessel, two elliptical bottoms, at least one feed water supply and steam removal connection pipe, an inlet header and an outlet header, a heat-exchange tube bundle connected to the same, wherein number Ntb of heat-exchange tubes in the bundle is selected depending on outer diameter dtb of the heat exchange tubes according to formulae. The technical result of the invention is an increased heat transfer efficiency in the steam generator with a limited number and maximum length of heat exchange tubes, which allows to use tubes employed in the industry.
