    摘要: A method to operate a power generation system and the device itself includes an oxy-fuel burner, a first heat exchanger assembly, and a rankine-cycle. The oxy-fuel burner generates an exhaust fluid submitted to an exhaust fluid line and the rankine-cycle is operated with the working media which is circulating separately from the exhaust fluid. The exhaust fluid line is provided with a recirculation line downstream the first heat exchanger assembly and upstream the working media heat exchanger extracting exhaust fluid from the exhaust fluid line, conducting extracted exhaust fluid to a compression unit to increase pressure and injecting downstream the extracted exhaust fluid into the oxy-fuel burner.

    摘要: This invention relates to a method and apparatus for increasing the final feedwater temperature associated with a regenerative Rankine cycle, said cycle commonly used in thermal systems such as conventional power plants, whose steam generators are fired with a fossil fuel and whose regenerative Rankine cycle employs a reheating of the working fluid. This invention involves the placement of an Exergetic Heater System in the feedwater path of the regenerative Rankine cycle. The Exergetic Heater System conditions and heats feedwater such that the temperature of the cycle's final feedwater as it enters the steam generator has reached a desired value. The Exergetic Heater System receives its driving steam from an Intermediate Pressure turbine extraction.

    摘要: A vapor compression cycle system is combined with a Rankine cycle system, with the two systems having a common suction accumulator from which the compressor draws refrigerant vapor for the vapor compression cycle system and from which a pump draws liquid refrigerant for circulation within the Rankine cycle system. The vapor from the Rankine cycle system expander is passed to the compressor discharge to provide a mixture which is circulated within the vapor compression cycle system to obtain improved performance. The heat exchangers are sized so as to obtain a non-complete evaporation, with the resulting two-phase fluid passing to the suction accumulator to provide liquid refrigerant to the Rankine cycle system and vapor refrigerant to the vapor compression cycle system.

    摘要: In a steam turbine power plant, a deaerator is heated and pressurized by extraction steam from the steam turbine for the purpose of preheating feedwater to the power plant boiler. Under certain conditions, the available steam to the deaerator is insufficient to adequately maintain pressure in the deaerator leading to steam voids with a rapid rise in deaerator water level which could cause damage to the deaerator, feedwater pumps or the turbine and lead to a power plant shutdown. A second source of steam is available to provide steam under these conditions and a control system for controlling the steam input into the deaerator is shown. Under conditions of falling pressure, if a certain rate is exceeded, the second source of steam is input into the deaerator to maintain adequate pressure for stable operation.

    摘要: A system and method for warmkeeping a steam generator such as a sub-critical steam generator is disclosed. Water extraction piping extracts water from a component of one of the water fill circuits of the sub-critical steam generator. A deaerator heating system having an inventory tank of water mixes the extracted water with the water in the tank, and heats the mix of water to a predetermined temperature level to generate heated deaerated feedwater. Feedwater piping forwards the heated deaerated feedwater at the predetermined temperature level from the deaerator heating system to the water fill circuits of the sub-critical steam generator. The water extraction piping, the deaerator heating system and the feedwater piping operate cooperatively to warmkeep the water fill circuits in accordance with the predetermined temperature level while the sub-critical steam generator is in the unfired stand-by mode of operation.
