A condensing system is provided. The condensing system may include baffle plate units having a substantially flat surface and openings configured for cooling fluid to flow through; and baffles attached to the baffle plate unit, the baffles oriented at an acute angle with respect to the baffle plate unit, the baffles having a flat surface and figured to diffuse a cooling fluid into a thin, turbulent film at a similar acute angle. A method of condensing a fluid is provided. The method includes defining a path for the fluid to be condensed to flow; spraying a cooling fluid against a baffle thereby creating a turbulent film of cooling fluid in the path for the fluid to be condensed and orienting some of the baffles to create a film of cooling fluid oriented in one direction and orienting other baffles to create a film of cooling fluid in a second direction wherein the path of the fluid to be condensed causes the fluid to be condensed to flow over films oriented in both the first and second directions.

Jet stream generating method and apparatus

An air-cooled condenser includes an upper header for distributing a vaporous medium to be condensed, a lower header for collecting condensate, spaced finned tubes with outer fins, the finned tubes being connected in parallel between the upper header and the lower header and cooled by a cooling air flow, means for draining the condensate form the lower header and extraction means for removing non-condensible gases from the condenser. The lower header is also used for distributing the vaporous medium to the finned tubes, so that the vaporous medium id fed into the finned tubes through both the upper and lower headers, and the extraction means are connected to each of the finned tubes at its portion facing the cooling air flow.

Air-cooled condenser

A cooling apparatus comprising an air-cooled heat exchanger, a plurality of louvres to control a cooling air flow passing the heat exchanger, a mechanism for operating the louvres and means for actuating the operating mechanism according to temperature of the heat exchanger. The actuating means comprises a bar having a first end and a second end and being of a material having a considerably lower thermal expansion coefficient than that of the heat exchanger, said bar being attached by its first end substantially at a first end of the heat exchanger, and means for controlling the position of the operating mechanism in dependence on a difference in displacements of the second end.

Cooling apparatus with automatic louvre operating mechanism

A pipe connection comprising a tube of plastically deformable material has an expanded end section received in a hole in a tube plate with a sealing ring received in an annular seat in the hole sealing the tube to the plate. The extreme end of the tube may be deformed conically into contact with one side of the plate to provide a rigid structural joint therebetween. More than one sealing ring may be employed. Methods of making the pipe connection may involve constricting a portion of the end section to provide a space between the end portion and the tube plate hole to permit the seal to be inserted, followed by expansion of the tube end to compress the seal and engage the tube plate wall in metal-to-metal contact. Other variations of the process are disclosed.

Pipe connection and method of making it

A jet condenser of the type comprising a water chamber in a mixing chamber (24) and an after-cooler (52), wherein the water chamber is subdivided in a narrower upper water chamber portion (38a) and a broader lower water chamber portion (39b). The after-cooler (52) is fixed at the junction (66) of both water chamber portions (38a, 38b). Cooling water is injected into the mixing chamber (24) by nozzles (40) of the upper water chamber portion (38a) where it flows in vertical direction. By the reduced width of the upper water chamber portion (38a) flow resistance of steam flow in the mixing chamber (24) and, thereby, undesired subcooling is substantially diminished. (FIG. 3).

Jet condenser

A dry-operated chimney cooling tower suitable for cooling warm water from a power station and operating with a natural draft, is provided with downstream jalousies to assist in frost protection and energy conservation. These jalousies can be capable of forming a 'diving bell' like enclosure around air radiators to contain warmed air therearound.

Dry-operated chimney cooling tower

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. Such difficulty is eliminated by locating the wet cooling apparatus at least partly in a box for conducting cooling air from the ambient into the cooling tower, the box being arranged inside the cooling tower and encompassing a dry surface heat exchanger provided after the wet cooling apparatus as regards the flow direction of cooling air. The air exiting from the wet cooling apparatus becomes warmed up while traversing the dry surface heat exchanger and, thus, does not diminish the draft of the cooling tower when mixing with the air flowing in through the main heat exchangers of the latter.

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. 2)

Air condenser installation

In a cooling apparatus operated by ambient air and an agent to be cooled which can have solid state at atmospherical temperatures, a housing such as a cooling tower (100) with air inlets and air closure means at the air inlets and large surface heat exchangers (3) arranged within the cooling tower (100) at its air inlets and divided into groups or sectors being in parallel connection are provided, with which the agent is cooled by the air streaming through the large surface heat exchangers (3). At least one pre-heating heat exchanger (20) is arranged in the air space (29) of each sector of the large surface heat exchangers (3), and the pre-heating heat exchangers (20) are in parallel connection with the large surface heat exchangers (3) of each sector.

Cooling apparatus

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. The spacing of the sections is substantially equal to a quarter of the circumference of the tubular member so that the rippled sections of the helicoidal member occupy diametrically opposed positions on the tubular member, the ripples being disposed generally transverse to the direction of airflow. The ripple-free sections, thus positioned, facilitate removal of impurities precipitated in the fin gaps (FIG. 9).

Helicoidally finned tubes

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).

Plant for utilization of low-potential waste heat of a gas-pipeline

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.

Internal fin tube heat exchanger

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.

Greenhouse with heating and ventilating means

Steam turbine power plants employ condensers for condensing the dead steam of the turbine. The required cooling in the condenser is obtained by cooling water which is, in case of dry cooling towers, injected into a mixing condenser. Recooling of the cooling water is obtained in surface heat exchangers of the dry cooling tower which carry off the heat by means of air. Where the employment of such system is jeopardised by the hazards of climatic conditions, it is suggested to associate water cooled heat exchangers with the surface heat exchangers and the dry cooling tower of the system. Such water cooled heat exchangers serve as auxiliary means where the cooling effect of the surface heat exchangers of the dry cooling tower fails to ensure a desired low condensation temperature in the mixing condenser.
