摘要： A continuous power system provides a continuous supply of power to a load in the event that primary power fails or is degraded. The continuous power system includes an electrical machine, a turbine and a flywheel coupled to a shaft. When utility power is present, the machine operates as a motor to drive the shaft. During outages, the electrical machine operates as a generator to provide power to the load. Kinetic energy stored in the flywheel drives the shaft during initial power interruptions. During further short-term interruptions, a thermal energy supply (or thermal storage device) is used to provide vaporized liquid to the turbine so that the turbine drives the shaft. If the power loss or failure is extended, the turbine is driven by vapor produced by an evaporator heated from an external fuel supply. Numerous methods and apparatus are also described for reducing system losses and improving overall performance.

摘要： In a method for optimizing operation of fossil fuel based power plants, in which the economical effects of the changes of selected operational parameters are determined under consideration of the required economical expenditure, and, based on these additional operational costs, it is determined if, when, and/or what kind of measures should be taken for minimizing the additional operational costs. According to the method, the improvement measures are initiated as a function of the cause of the additional operational costs according to a hierarchal catalog of measures. The measures are: an immediate intervention into the operational course; a later measure implemented during a short shutdown; a later measure implemented during a service shutdown; and/or an operational downtime for a revision.

摘要： A drum-type heat-recovery boiler (2) forms, together with the feedwater tank/deaerator (6) and condenser/hot well (4), the steam system of a combined-cycle power station. This steam system has a plurality of containers (10, 16, 22, 6, 4) working at different pressure stages. Some of the containers are formed by steam drums (10, 16, 22). The container of the lowest pressure stage is the condenser/hot well (4). The high-pressure steam drum (10) is connected directly to the intermediate-pressure steam drum (16) via a water line (25) and a steam line (39). The intermediate-pressure steam drum (16) is connected directly to the low-pressure steam drum (22) via a water line (27) and a steam line (41), and the low-pressure steam drum (22) is connected directly to the feedwater tank/deaerator (6) via a water line (29) and a steam line (43). During the start-up, the water/steam is circulated cascade-like from the containers of a respective higher pressure stage to containers of a respective lower pressure stage without operation of a bypass system (31, 32, 33) and heat dissipation in the condenser/hot well (4). Thus the heat remains completely in the water/steam cycle, a factor which permits a very quick start-up of the power station.

摘要： The present invention is a dynamic condensate system which can replace the hotwell designs currently available. The dynamic condensate system enhances the performance of a compact closed Rankine-cycle or similar engine using a single small-volume apparatus which actively separates noncondensables from the subcooled condensate; lowers condenser pressure; boosts feed-pump inlet pressure; allows the hotwell volume to remain at ambient pressure; and eliminates lateral acceleration effects on the engine. The dynamic condensate system includes a liquid ring pumping element and a side-branch hotwell. There is an inlet to the liquid ring pumping element from a condenser of the engine for receiving liquid and vapor flow. An outlet from the liquid ring pumping element provides a flow path for liquid from the dynamic condensate system to a feed pump of the engine. A discharge port from the liquid ring pumping element provides a flow path to the side-branch hotwell to remove vapor from the liquid and vapor flow from the condenser. Finally, there is an output from the side-branch hotwell connected to the inlet to the liquid ring pumping element for reintroducing remaining liquid captured during removal of the vapor.
