The entrance of fluid into the boiler through the pipe 39, and the output of the heated coolant from the boiler is carried out from the manifold 29 by the pipe 40.

Flue collector ring 26 is located on the cantilever support, marked with the letter "K" for free movement, and the outer rear annular manifold 22 is mounted on a support, where you set the frame, and when the heating of the heat carrier boiler is free to expand and move.

Ring collectors 21, 22, 26 and 29 are heat-exchange elements of the boiler, which increases the efficiency of heating the coolant.

With a vertical arrangement of the boiler installation, oil-gas burning device installed at the top and bottom of the boiler is the flue leading to the chimney or exhaust, depending on how the boiler works: under the blow-or balanced-draft, while vozduhonagrevatele device of the heater is made in the form of heat, one or more, coiled metal strips 17, which are the fins, and is located between the casing 13 and the outer cylindrical surface of the boiler. With this arrangement, the boiler is missing the pipe vytvarene perform boiler combustion chamber 20 is a stub, located in the center of the boiler and is a two-way movement of products of combustion. The boiler has only one annular duct 28 which, as in the furnace, installed the tubes 27, curved in the form of loops having the shape of an ellipse, and the ellipse pipe 27 can lie in any plane, and the pipes can be placed in several rows. The boiler has four annular collector: front outer 21, back 22 external, front inner 29, which is the output of the collector is heated coolant from the boiler, and the rear internal fuel manifold 26.

The boiler is equipped with two additional surfaces, such as paths, one path 34 is a front annular (hollow ring), in which is inserted and attached burner device 3, the second circuit 35 is located at the end of the combustion chamber and annular (hollow ring). Through the circuit 35 is inserted and secured a cylindrical collector radiative-convective economizer 19. The circuits 34 and 35 can operate separately ( in parallel), and sequential connection. Above the annular duct has an explosive valve, pipe 27 are provided with a metallic membrane-swirlers 42, and a cylindrical second heat exchange surface, which, as the membrane does not reach the front annular manifold 21, thereby providing the output of products of combustion from the peripheral space of the furnace 20 in the annular duct 28.

When the coolant is heated in the circuit 31, which has a nozzle inlet 32 and outlet 33 of the coolant, as well as in the tube of the technological circuit, consisting of two parts 34 and 35 ( front and rear).

The movement of products of combustion is prototechno movement of the coolant in the boiler plant, the yield of products of combustion from the furnace chamber osushestvlyaem space heat exchanger pipes 27 to the front of the boiler, where due to the cylindrical gasoneftanaya 25 combustion products turn 180oand received in the second annular duct 24, where, washing the tubes 23, the products of combustion come in economizer chamber and giving thermal energy to the heating surfaces 19 and 37 of the economizer, leave the boiler plant through pipe 12 to the exit of the combustion products.

Boiler installation on the second version execution works as follows.

The heated coolant enters into the cylindrical collector 19 economizer and heat pipes 37 enters the collector 22 (the first step of heating the coolant). From collector 22, the coolant passes through the pipe 27 located in the annular duct 28 and is heated, enters the collector 21 (the second step of heating the fluid, where the fluid moving through the pipe 27 located in the combustion chamber, flows into the collector 26 (the third step of heating the coolant), and from the manifold 26 through the pipes 27 passes into the reservoir 29 from which the heated coolant is directed to the consumer (the fourth step of heating the coolant). The movement of the burning mixture of fuel with air is distributed from the front of the boiler for Central ru, and the products of combustion move along the peripheral part of the furnace to the front of the boiler 1 in the annular space of the pipe 27.

In a metal ring manifold coolant moves in the sections 48 and 50, with the through holes provided in the walls 48, allow the coolant from one partition to another, and combined with sections of the coolant circuit.

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.
