The cooled gas is supplied under pressure from a header of the input gas through the supply pipe (not shown) in the chamber gas inlet through holes 10 under the nozzles in the top and/or bottom wall of the chamber. Evenly filling the chamber entrance, the gas is distributed through the pipes. Three-stage gas inlet to ensure the consistent expansion of the gas stream and the alignment of the velocity field, absorbs hydraulic shocks in the arteries and contributes to a more uniform distribution of gas through pipes. This promotes a more efficient use of heat exchange surfaces and increases throughput AVO gas.

Gas inlet or outlet chamber also comprises not less than two load-bearing partitions arranged between side walls and provided with through orifices. One chamber wall is made as tube plate with orifices defining grid structure and adapted to receive heat-exchanging tube ends. One chamber wall has orifices to receive pies to connect thereof with gas inlet or outlet manifold, which supplies gas to or discharges gas from the chamber. Orifices for connection pipe receiving, load-bearing partition orifices and tube plate orifices define communication system to connect gas air cooling plant with gas pipeline. The communication system has several stages with orifices formed so that orifice number at each stage successively changes in gas flow direction. For gas inlet chamber above number increases, for gas outlet chamber the number decreases.

EFFECT: possibility to equalize velocity field, reduced hydraulic hammer, which results in reduced power losses in pipeline conveying gas to be cooled and in increased thermal performance of air cooling plant as a whole or air cooling plant section, increased economy of plant production and operation.

FIELD: engineering of collectors for injection or drainage of gas for apparatuses for air-based gas cooling.

SUBSTANCE: device has bearing frame, on which not less than three cradle supports are mounted for supporting body of collector for injection or drainage of gas and for abutment of branch pipe connected thereto for connection to gas main, and no less than four portal supports for temporary technological holding by plane, rotation angle and position along collector for injection or drainage of gas of branch pipes with flanges for connection to chambers for inlet or outlet of gas of heat-exchange sections of air-based gas cooling apparatus adequately to position of contact surfaces of response flanges and mounting apertures in them in chamber for inlet or outlet of gas. At least two cradle supports are positioned with possible abutment of body of collector for injection or drainage of gas against them in accordance to suspension scheme, each one primarily between additional pair of portal supports, mounted below outmost and adjacent flanges of branch pipes for connection to chambers for inlet or outlet of gas. Each portal support is made with detachable beam, which is provided with device for temporary holding by plane and rotation angle of flange of appropriate branch pipe and for connection of it to body of collector for injection or drainage of gas in planned position.

EFFECT: simplified construction of building berth while providing for high precision of manufacturing of collector for drainage or injection of gas.

FIELD: heat and power engineering, namely tube walls of inlet or outlet chambers of apparatus for air cooling of gas or section of such apparatus.

SUBSTANCE: tube plate of chamber of gas inlet or gas outlet of heat exchange section of apparatus for air cooling of gas includes plate in the form of parallelepiped, mainly right-angled one. Said plate includes system of through openings for ends of heat exchange tubes of tube bundle. Said openings are arranged by rows along height of wall at pitch of their axes in row being in range (1.7 - 3.4) d; at pitch of rows along height of wall being in range (1.6 - 3.4)d where d - diameter of openings. Said openings are shifted in adjacent rows by value 0.35 -0.65 of pitch in row. Projection of surface area of wall carcass onto mean plane of tube wall exceeds by 4 - 12.5 times projection of total surface area of voids of wall on the same plane. Portion of continuous cross section is arranged along perimeter of tube wall for forming rigidity band of tube wall. Surface area of rigidity band consists 16.0 - 45.0% of tube wall surface area.

EFFECT: enhanced strength, lowered metal consumption of construction due to optimal parameters of tube wall.
