摘要： A combined cycle power plant that includes a gas turbine and HRSG engaged with a steam turbine via a water steam cycle having higher and lower pressure levels. The CCPP further includes a fuel line and fuel preheater. A higher pressure feedwater line delivers higher pressure feedwater to a higher pressure feedwater branch that extends through the fuel preheater, the high pressure feedwater branch including upstream and downstream segments defined to each side of the fuel preheater. A lower pressure feedwater line delivers lower pressure feedwater to a lower pressure feedwater branch. The downstream segment of the higher pressure feedwater branch is combined with the lower pressure feedwater branch at a junction point and a combined feedwater line extends therefrom. A first heat exchanger exchanges heat between the combined feedwater line and fuel line. A second heat exchanger exchanges heat between the higher pressure feedwater branch and fuel line.

摘要： A method and an apparatus for feed-water control in a steam generating plant such as a boiling water nuclear reactor having motor-driven feed-water pumps and turbine-driven feed-water pumps for supplying feed-water to a steam generator, in which the feed-water flow through the turbine-driven feed-water pumps is controlled to be maintained constant, while reducing the recirculation flow discharged from the turbine-driven feed-water pumps and fed back to the inlet thereof, so as to reduce the amount of feed-water supplied to the steam generator by the motor-driven feed-water pumps, whereby variation of water level in the steam generator during switching between the two kinds of feed-water pumps is suppressed.

摘要： A system for controlling the water level in a boiler, including a liquid level adjuster, conduits connecting the liquid level adjuster to the boiler through housings mounted on the boiler and membranes positioned between the boiler and the conduits to transmit fluid pressure from the boiler to the liquid level adjuster while preventing fluid communication between the boiler and the liquid level control system. Valved bypass ducts extend from the housings to the top of the boiler so that expansion of the water in the liquid level control system due to the firing of the boiler is accommodated by overflow into the top of the boiler rather than by rupture of the membranes. Graduated water columns are provided to permit calibration of the liquid level adjuster, and valves are included in the liquid level control system adjacent to the liquid level adjuster so that the liquid level adjuster may be isolated from the rest of the system and checked for proper operation at any time.

摘要： A method includes determining, via a processor, a commanded fluid flow rate of a fluid entering or exiting the drum of an industrial system, wherein the commanded fluid flow rate comprises a rate of fluid entering the drum of the industrial system, exiting the drum of the industrial system, or a combination thereof. The method additionally includes determining, via the processor, a measured flow rate of the fluid. The method further includes determining, via the processor, a variable multiplier based at least in part on the commanded fluid flow rate and the measured flow rate; and deriving, via the processor, a multiplied flow rate command for the industrial system by applying the variable multiplier to the commanded fluid flow rate.

摘要： A mechanical arrangement to reduce drastically the energy consumption for pumping condensate to feed high pressure vapor generators for power generation, industrial processing, and heating systems. Involved is a method to pump the condensate into one condensate receiver located at the sucton side of the condensate feed pump, and to bleed high pressure vapor from the vapor generator into the condensate receiver for imposing a pressure head upon the condensate therein to be approximately the same as that in the generator, and thus the pressure difference between the suction side and the discharge side of the pump is also drastically reduced while pumping the condensate into the generator, with the result that the energy consumption of the pump is also drastically reduced. The receiver is full of high pressure vapor while the condensate therein is drained by the pump, and the high pressure vapor means energy. Further new methods are involved to reduce the vapor pressure in the receiver by returning the vapor to the system or to utilize it for other purposes, as disclosed in the application. Generally speaking, at least two closed receivers operated in series are required for the method of restoring the vapor in the receivers to the generator after the condensate is pumped into the generator. The invented disclosed receivers are also designed for condensate heating with almost no energy consumption.
摘要翻译： {PG，1 A机械布置，大大降低了泵送冷凝水的能源消耗，为发电，工业加工和加热系统供应高压蒸汽发生器。涉及的方法是将冷凝物泵送到位于冷凝水进料泵的壳体侧的一个冷凝物接收器中，并将高压蒸汽从蒸气发生器排出到冷凝物接收器中，以将压头施加在其中的冷凝物上，大致为与发电机相同，因此在将冷凝物泵送到发电机中的同时，泵的吸入侧和排出侧之间的压力差也急剧减小，结果是泵的能量消耗也急剧降低。接收器充满高压蒸汽，而其中的冷凝物由泵排出，高压蒸汽是指能量。涉及通过将蒸气返回到系统或将其用于其它目的来减少接收器中的蒸气压的其它新方法，如本申请中所公开的。一般来说，在将冷凝物泵送到发电机中之后，将接收器中的蒸汽恢复到发电机的方法需要串联操作的至少两个封闭的接收器。本发明公开的接收器也被设计用于几乎没有能量消耗的冷凝物加热。

摘要： The present invention relates to an automatic water supply-type steam generator using vapor pressure for creating the optimum vacuum pressure inside a pressurized water supply tank, and for smoothly providing water to the pressurized water supply tank by using the strong aspiration force that is created by means of the vacuum pressure while continuously generating steam. The present invention is characterized by allowing control of the vacuum pressure to the optimum state when creating the vacuum pressure inside the pressurized water supply tank by introducing an adequate amount of outside air from the atmosphere through an air vent. In addition, the present invention is characterized by providing a means for cooling the pressurized water supply tank so as to control the vacuum pressure inside the tank to the optimum state.

摘要： Fuel and oxidant feed rates into a gasifier 202 are regulated by monitoring overall output 14 and comparing with a pre-selected setpoint valve 10. An overall load demand signal 50, responsive to this comparision is generated and used as an input to control 102 oxidant feed rate. The heating value of the product gas is measured 76 and used to control 64 overall fuel feed rate to the gasifier 202. For a two stage slagging gasifier, the present invention controls 114 fuel feed rate to the slagging stage 210 responsive to the measured slagging stage reaction temperature 128.
