摘要： A power plant (10) including a boiler unit portion (12) and a gas turbine unit portion (14) operable in multiple modes, including operation of the boiler unit portion independent of the gas turbine unit portion. Exhaust gas from the gas turbine is cooled in a heat recovery steam generator (HRSG) (52, 54) where steam is produced. The exhaust gas may also be provided to support combustion in a separately fueled boiler (16). The exhaust gas may be extracted from any location within or downstream of the HRSG. Steam produced in the HRSG and/or in the boiler may be supplied to a steam turbine unit (42, 44, 46). Dampers (60, 62, 74) are provided to selectively direct the gas turbine exhaust to the boiler or to bypass the boiler. An existing boiler fired steam power plant may be reconfigured to have the described arrangement.

摘要： A system and method for increasing the efficiency and/or power produced by an integrated gasification combined cycle system by increasing the integration between the air separation unit island, the heat recovery steam generator and the remainder of the system. By integrating heat produced by the heat recovery steam generator in the remainder of the integrated gasification combined cycle system, heat may be utilized that may have otherwise been lost or used further downstream in the system. The integration helps to increase the efficiency of the combustion reaction and/or the gasification reaction used to produce the syngas utilized in the integrated gasification combined cycle system.

摘要： A system and method for producing multiple syngas products. In one embodiment (FIG. 5) a syngas producing system (200) includes a gasifier (210) and a hydrocarbon steam reformer (226). The gasifier (210) is configured to react a solid or liquid carbonaceous material (212) and provide a first syngas product (222). The reformer (226) is coupled to receive sensible heat from the first syngas product (222) and drive an endothermic reaction in which a second syngas product (238) is produced from a liquid or gaseous hydrocarbon supply (150). In a method of processing fuel, a solid or liquid carbonaceous material (212) is provided to a gasifier (210) in the form of a slurry, which is converted into a first syngas product (222) in an exothermic reaction. A liquid or gaseous hydrocarbon supply (150) receives sufficient sensible heat generated during the exothermic reaction to convert the liquid or gaseous hydrocarbon supply (150) into a second syngas product (238).

摘要： A gas turbine cycle that utilizes the vaporization of liquefied natural gas as a source of inlet air chilling for a gas turbine. The cycle uses regeneration for preheating of combustor air and offers the potential of gas turbine cycle efficiencies in excess of 60%. The systems and methods permit the vaporization of LNG using ambient air, with the resulting super cooled air being easier to compress and/or having fewer contaminants therein. As the air is easier to compress, less energy is needed to operate the compressor, thereby increasing the efficiency of the system. A portion of the vaporized natural gas may be used as the combustion fuel for the gas turbine system, thereby permitting multiple turbines to be operated using a single topping cycle. In alternative embodiments, the vaporization of the LNG may be used as part of a bottoming cycle to increase the efficiencies of the gas turbine system.

摘要： A method of generating power from residual fuel oil that is deasphalted with a flow of process steam to produce a deasphalted oil stream, a pitch stream, and a deasphalting condensate stream. The deasphalted oil stream is burned in a pressurized oxygen-bearing gas to produce a pressurized hot gas stream. This pressurized hot gas stream is expanded in a turbine that produces shaft power and an expanded gas stream. The expanded gas stream is cooled by transferring heat from it to a flow of feed water that becomes steam. A portion of the steam becomes at least part of the flow of process steam used to deasphalt the residual fuel oil, thus integrating the deasphalting and the steam generation.

摘要： A gas turbine power plant having a heat recovery steam generator that generates steam at high and low pressures. The high pressure steam, which is superheated, is partially expanded in a steam turbine, thereby producing shaft power. All of the partially expanded steam is then combined with low pressure steam. The combined steam flow is superheated and then injected into the combustor of the gas turbine to increase power output and reduce NOx.
