    摘要: A method and apparatus for recovery of heat from the flue gas of the combustion furnace of a steam boiler or power generation plant uses a heat pump heat extracted from a lower temperature point in the system to a higher temperature point in the system. The flue gas is passed through an economizer to preheat the boiler feed water. The flue gas then passes to a direct contact gas cooler where a second stream of cooling water extracts heat from the flue gas. The second stream of cooling water is passed through the evaporator of the heat pump to heat a refrigerant. The refrigerant is compressed and then condensed in thermal contact with the boiler feed water to heat it before it enters the economizer. In a second embodiment a power generation plant has a steam turbine and an auxiliary vapor turbine. The flue gas is passed through a gas cooler and gives up heat to a stream of cooling water. The heat is extracted from stream of cooling water and pumped by a heat pump to heat a stream of refrigerant which drives the vapor turbine thus generating additional power. A third embodiment is also disclosed.

    摘要: An apparatus of the heat exchanger type embodying a plurality of plates arranged in spaced parallel relation with one another to define a stack of exchanger plates. The stack of plates are arranged to define fluid and vapor passages with separators being positioned in said passages to maintain the plates in spaced relation. The stack of plates are positioned between pressure plates which have top, bottom, and side covers either supported thereon or connected thereto with the entire assembly held together by suitable clamp plates. The side covers utilize fluidic means to apply pressure to the pressure plates so that said heat exchanger utilizes the general principle of nearly equalized pressure between outside and interior surfaces.

    摘要: An article, such as an impeller, is mounted for torque transmission by a shaft by positioning the article in contact with a threaded collar engaging tapered threads on the shaft and applying an axial force to the article to move and tighten the threaded collar on the tapered threads. The axial force is applied to the article by a clamping collar which contacts the article only in an area spaced from a central bore of the article in order to deflect a portion of the article defining the central bore radially inward toward the shaft. In one embodiment, two impellers are positioned back-to-back, with one impeller receiving an axial force spaced radially from a central bore of the impeller by an annular formation on the other impeller.

    摘要: A refrigeration or liquid chilling system embodying a compressor, condenser and evaporator. The system has interposed therein, downstream from the evaporator, a vortex generating structure which utilizes the energy generated by the vortex to compress the vapor coming out of the evaporator prior to discharging it to the inlet of the compressor. This arrangement tends to improve the efficiency of a liquid chilling system or, alternatively, to reduce the cost per unit of refrigeration produced.
