In addition, in order to increase the efficiency of heating the combustion chamber, they have a narrowing section in length and are open from the ends. FIG. 1 shows the proposed installation; in fig. 2 - heater, in two projects, 1 and their horizontal axis are products of different diameters. The heaters 5 contain a heat insulating valve 10, which is integral with the heat insulating walls, and the screen width is determined by the width of the local heating zone. The screen and side walls are made of heat-resistant metal double, and the cavity between them is filled with an insulating material / 2. The screen 10 with side walls // together with the surface of the product1 2 forms a combustion chamber of the heater. Gas manifolds 14 are attached to the shield of SUPPORT brackets 13, in which the burners 15 are screwed, and the number of burners is determined by the latitude of the local information. Gas manifolds of neighboring heaters are connected} 1Ы between each other by means of triple-16 metal-bend flexible metal strings 1 and eight 8. Neighboring; 1e heating elements are connected between co6oii strip mn 17, free running the same axes are mounted free-rotating mines, spindle wheels 19. Combined heaters between themselves form a common chamber; / combustion 20 of the heating device. Extreme bottom heaters are fixed by high un21 m.

Этому способствует также то, что вторичный воздух, необходимый дл полного сжигани газа, может засасыватьс через верхнюю часть открытого торца кас еры сгорани за счет энергии струи газовоздушлой Омеси с первиЧ1ны.м воздухом, вследствие чего горение развиваетс и заканчиваетс в .камере сгорани .Burners 15 local heating - injection, high pressure, incomplete preliminary gas displacement ii (a 0.7); they are supplied with a metallic :.): combustion stabilizers and are located in the combustion chamber 20 at an angle of 35-40 ° to the surface of IZDEL1 I, and.- the screen 10 is tilted to the surface of the product 2 at an angle with a reduction in the cross-sectional area of the combustion chamber, which provides an intensification and increase in profitability of burning. This is also facilitated by the fact that the secondary air necessary for the complete combustion of gas can be sucked through the upper part of the open end of the combustion section due to the energy of the jet of the gas-air Omesi with primary air, as a result of which the combustion develops and ends in the combustion chamber.
Продукты сгорани частично у.ход т через щель, образованную стенкамн // экрана и поверхностью издели 2 (посто гктво величины щели поддерживаетс копирными колесами 19), а часть продуктов сгорани благодар инжектирующей способности факелов горелок 15 перетекает из одной камеры сгорани в другую, что значительно повышает илтеисификацию и экономичность нагрева.The products of combustion partially penetrate through the slit formed by the walls of the screen // and the surface of the product 2 (constant size of the slit is supported by the copier wheels 19), and part of the combustion products due to the injecting ability of the torches of the burners 15 flows from one combustion chamber to another, which significantly increases illiteration and profitability of heating.
