  • Patent number: 5078205
    Abstract: A cooling system for condensing the exhaust steam of steam turbine plants, particularly of power plants, comprises a mixing condenser connected to the outflow of the steam turbine, a dry cooling tower connected to the cooling water circuit of the mixing condenser, and a wet cooling apparatus provided inside the cooling tower.Although wet cooling apparatus seem to be suitable to additionally increase the cooling performance of the cooling tower and, thereby, its effective operation even in case of exceptionally high ambient temperatures, the air exiting from them is cooler than the air flowing in through the main heat exchangers of the cooling tower and, therefore, the draft of the latter suffers deterioration when the two air streams mix one with the other. It means that the effectiveness of complementary cooling is may be impaired.

  • Patent number: 4909309
    Abstract: Air condensers are liable to suffer from undercooling which may entail frost damages and represents, in any case, thermo-dynamic losses. In order to prevent undercooling the working length (X) of the cooling surfaces of the air condensers (10) are controlled by shutters (28) which are associated with a drive mechanism (30) operated dependent on the temperature difference of condensates withdrawing from a first and a further row of tubes (18, 20) of the air condensers. By shutters (46) located in a gap (44) between the air condensers (10) the cooling air is enabled to recirculate whereby danger of frost and undesired risings of the temperature level of condensation may be avoided and impeded, respectively. A casing (68) encompassing the air condensers (10) and provided with shutters (64, 66) at its bottom and top permits starting without danger of frost likewise by means of recirculation. (FIG.

  • Patent number: 4830102
    Abstract: A heat exchanger having a plurality of parallel pipes arranged in lines and strips of fin plates fixed to the pipes perpendicularly to the lengths thereof. Turbulence-forming structures are cut out of the fin plates and are bent up at 90.degree. with respect to the planes of the plates, such structures functioning as fin plate spacers and as baffles to direct a fluid medium of inferior heat transfer coefficient which flows in a direction parallel to the planes of the finned plates and perpendicularly to the pipes. The pipes are adapted to conduct a fluid medium of superior heat transfer coefficient. The turbulence-forming structures are disposed in lines on each side of the lines of pipes and in rows which are substantially tangential to the opposite sides of the pipes. The heat exchanger may have a plurality of lines of pipes spaced equally transversely from each other and transvetsely of the direction of flow of the fluid medium of inferior heat transfer coefficient.

  • Patent number: 4677307
    Abstract: Subject of the invention is a process for the realization of cogenerative supply of electricity and heat, and in given case for their combination with waste heat recovery, particularly in case of combined (gas-steam) cycle industrial power plants.The essential feature of the invention is that during the season without heat demand the condenser with heating capacity N is operated by cooling with cooling tower, and during the heat-intensive season it is operated at a higher temperature required for the heat supplying operation mode, while the cooling tower (7) is disconnected partially or completely, and the resultant reduction of the specific expansion and heating capacity of the steam turbine (4) is compensated by increasing the steam parameters and steam output of the waste heat recovery boiler (3) with supplementary firing (11).

  • Patent number: 4538677
    Abstract: A helicoidally finned tube for use mainly in heat exchangers. The tube comprises a cylindrical tubular member which carries or is integral with a helical member the turns of which form the fins of the tube. The fins are provided with ripples which extend from the outer rim of the fins inwardly and the depth of which diminishes toward the tube center. The ripples serve for diverting a cooling medium inwardly to hotter parts of the tube thereby improving its heat transfer performance. The helicoidal member has rippled sections alternately with level sections, the rippled sections subtending an angle not exceeding about 90 degrees and both types of sections on successive turns registering with one another in the direction of the axis of the tubular member.

  • Patent number: 4420950
    Abstract: The invention relates to a plant for utilization of low-potential waste heat of a gas-pipeline compressor station in a heat consumer which is outside the station such as e.g. district heating systems for homes, for industrial or agricultural purposes. The compressor stations of this type have a compressor driven by a gas motor or gas turbine.The improvement is in that a surface heat exchanger (7) cooled with liquid, preferably with water is provided for cooling the gas after leaving the compressor and being warmed in the course of compression. The heat exchanger is connected to the heat consumer through a liquid conduit having a circulation pump in it (FIG. 1).

  • Patent number: 4265275
    Abstract: An internal fin tube heat exchanger comprises a cylindrical tube having on its inside a continuous heat exchange member with a plurality of legs branched from a central longitudinal extending member. The heat exchange member can be metal strip cut with a plurality of ribs disposed at an acute angle thereto, so that when the member is pulled into the tube, the ribs do not resist movement in one direction but do resist reverse movement in the opposite direction, which opposite direction is also the direction of flow of the fluid within the tube. Thus the fluid does not dislodge the heat exchange member. The ribs can be cut in various patterns and the strip is rotated when being drawn into the tube so as to impart a twist thereto, thereby to position the ribs all about the periphery of the tube. The ribs can have feet thereon that extend either peripherally of the tube or longitudinally of the tube.

  • Patent number: 4166339
    Abstract: The heating means of a greenhouse is combined with a source of waste heat. Preferably, the heating means is a surface heat exchanger placed in the flow path of air which is circulated in the greenhouse while the waste heat source is a mixing condenser of a steam turbine power plant. The condensate from the mixing condenser is cooled down in the surface heat exchanger which warms up the air in the greenhouse. If it has water spray means associated with it which is operated dependent on the moisture content of circulating air, cooling of the condensate and warming up as well as moistening of circulated air is effected by the same system at the expense of waste heat.
