    摘要： A complete bearing-sealed root vacuum pump system capable of promoting vacuum ability of a condenser of a power plant provides a complete bearing-sealed structure. All chambers are isolated effectively so that liquid cannot flow there between and thus not to destroy the root vacuum pump. Therefore, the lifetime of the root vacuum pump is prolonged. The heat exchangers are arranged between the root vacuum pumps and the front stage pump so as to return the condensed water. The condenser vacuum is improved and thus the power generation efficiency is promoted, and power consumption is lowered. As a result a large power plant can save several thousand tons of coals per year.

    摘要： The engine has a thermodynamic expander (21) for extracting work from a vaporised working fluid (22) that is fed to a feed for it. There is also a condenser (26) downstream of the expander for condensing expanded vaporised working fluid that is exhausting from the expander. A liquid tank (28) is downstream from the condenser, and pump means (29) is located downstream from the liquid tank for pumping out condensed working fluid (38). Further, there is a means for heating (50) and at least partially vaporising working fluid pumped to it from the pump and feeding the heated working fluid to the expander. The heating means itself has at least one inlet for the working fluid pumped to it, and at least one output from which the working fluid is fed to the expander.

    摘要： Techniques for cogeneration of heat and power are disclosed. A cogeneration system includes: a conduit loop configured to carry a working fluid using a Rankine cycle; a valve system disposed along the conduit loop, including valves configured to manage flow of the working fluid through a chamber; a backflow vapor line disposed along the conduit loop, configured to direct working fluid in a gaseous state to the chamber, such that the working fluid in the gaseous state displaces working fluid in a liquid state in the chamber and the working fluid in the liquid state advances through the conduit loop without requiring a mechanical pump; and a heat exchanger disposed along the conduit loop, configured to extract heat from the working fluid and direct the heat to a practical use.

    摘要： A combined cycle power plant that includes a gas turbine engine, a heat recovery steam generator (HRSG), a steam turbine, a primary condenser, a condensate extraction pump, a gland steam condenser, and a cooling module. The HRSG generates steam. The steam turbine receives steam from the HRSG. The primary condenser is fluidly coupled to the steam turbine and receives a first portion of exhaust steam from the steam turbine. The condensate extraction pump is fluidly coupled to the primary condenser and receives a condensed first portion of exhaust steam. The gland steam condenser is fluidly coupled to the steam turbine and receives a second portion of exhaust steam from the steam turbine. The cooling module is fluidly coupled to the gland steam condenser and supplies a cooling fluid to the gland steam condenser. The cooling module is fluidly isolated from the condensate extraction pump.
