 ; -G: .-. The invention relates to energy and can be used to burn gas fuel and to produce a drying agent for drying plants. Known heat generator, with. It holds, an air duct branch pipe, a squib fire tube shaped pipe with a burner inserted into its internal cavity and a swirler tlj installed by it. The lack of data on the heat log of the engine is the incompleteness of the combustion of fuel in view of the fact that volts (personal air entering n) the for {openings of the flame tube, and the combustion products (light entering through the radially located burner) create lengthwise, flame pipes uneven velocity profile of the gas flow, which leads to incomplete combustion of the fuel.The closest known to the proposed is the heat generator, which is enclosed with an air inlet radial pipe body, covering the formation of a ring There is a perforated pipe located at the distance from the rear torsa of the hull and fitted on the side of the latter coaxially mounted with a burner and curtainer. A disadvantage of the known heat heater is the incomplete burning of the pipe because of the heat supply from the burner side Avnom -: ness floor velocity at the entrance both to the swirler and to the mixing holes of the Zharové pipe. This delta is achieved by the fact that the flame tube in the zone of the heating ring is movable in the longitudinal direction of the spool valve, and the distance from the rear end of the body to the gate and the tube is, respectively, (O, 01 - 0.1) and (O, 15 - 0, ZO) from the diameter of the latter. In addition to Totx), the air inlet sleeve of the housing can be equipped with a divider in the angle bracket, which is parallel to the axis of the shell, with the imaginary extension of the angle bars located tangentially to the flame tube. FIG. 1 shows a longitudinal section of the heat generator; in fig. 2 is a section A-A in FIG. 1. The heat generator contains, equipped with an air supply for the radial nozzle 1 case 2, which encompasses with the formation of an annulus) of the gap 3, a punched heat pipe 4, located at a distance from the rear end 5 of the case 2 and supplied from the latter coaxially installed by the bee 6 and the front end 7. Zharov the pipe 4 in the area of the gasket 6 is provided with a slide valve e, movable in the 1 podolny direction, and the distance from the rear end of the body 5 to the gate 8 and the flame pipe 4 equals (0.01-0.1) n (0.15 - O ZO) from the diameter of the afterbirth him The air inlet 1 of the housing 2 can be equipped with a divider 9 in the form of a square located parallel to the axis of the housing -2, and the imaginary 1 extension of the shelves of the square is located relative to the flame tube 4. The heat generator works as follows. Through the radial nozzle 1 in the annular gap 3 serves air. The primary air enters through the gate 8 and the swirler 7 into the flame tube 4, secondary through the perforation in the tube 4. Under the longitudinal sliding gate 8, the primary and secondary air can be redistributed. Fuel is supplied through burner 6 and mixed with the primary swirling air stream burns. Gate 8 contributes to uniform air distribution in front of the fireplug 7 of the flame tube 4. Divider 9, made in the form of angle | 1ika, Piz & evenly distribute secondary air through perforations of the flame tube 4. Distance from rear end 5 of housing 2 to slide gate 8 is (0.01-0.1) of the diameter of the flame tube 4, in this range the carbon monoxide content in the combustion gases does not exceed 0.05%, and the distance between the rear TqpuoM 5 and the flame tube 4 is (0.15 -0.30) diameter of the latter. With an increase in the distance of more than 0.15 of the diameter, the content of nitrogen oxide in the combustion products is less, and at a distance of 0.3 of the diameter of the flame tube 4, the content of nitric oxide is almost equal to O and a further increase in the distance is impractical, since this leads to an increase in the length of heatdragber . Execution of the flame tube, provided in the burner zone with a longitudinally movable spool gate, with a distance from the rear end of the body to the flame tube, respectively (O, 01 - 0.1) and (0.15 - 0.30) of the diameter the latter and, besides, the possible implementation of the air inlet pipe of the housing equipped with a divider in the form of a square located parallel to the axis of the housing with an imaginary continuation of the square’s shelves located relative to the flame tube allows the use of a heat generator. 1. Thermal generator comprising a housing provided with an air-supplying radial nozzle, forming a perforated flame tube located at an annular gap, located at a distance from the rear end of the housing and fitted on the side of the latter coaxially mounted with a burner and swirler, and with that, in order to improve reliability by improving the completeness of the combustion of fuel, the heat pipe, in the burner zone, is equipped with a longitudinally movable slide valve, and the distance from the rear end of the housing to the flame tube and is suitably 0.01 - 0.1 and 0.15 - About 30 final diameter. 2. Tester Generator 4) according to claim 1, of which is the case that the air inlet pipe of the body is equipped with a divider in the form of a square; located parallel to the axis of the hull, and the imaginary extension of the shelves of the square is located with respect to the flame tube. 1 Information sources that are taken into account during the examination 1.
