The accessory ignition of the fuel may contain the actuator and the charge placed inside a perforated cylinder mounted coaxially within the cylindrical body, connected to the second additional tube. Introduction to installing DL is the study of objects at high temperatures, containing working chamber with boot box, made with the possibility of overlap, placed inside the chamber, the device for fastening the object and at least one fuel reservoir with water jets, a device for supplying fuel, a pipe connected at one end with a device for supplying fuel, and the other to the collector, the ignition device, at least one of the tray, setting it under the manifold and the introduction of at least one pair of optional drawers and ignition of fuel, each of which are connected respectively to the first and second pipes tray, allows reliable remotely to produce ignition at any point in time it is difficult combusting fuel (kerosene, diesel oil) in the working chamber, thereby to secure variable given algorithm thermal field in the process chamber during heat exposure on the object. Placement of feeders and ignition of fuel at a given distance from the working chamber, the second additional tube in front of the device ignition device of this cooling pipe exclude thermal effects on the drawer, and ignition of the fuel and, consequently, premature tripping. Perform additional feeder fuel provided the fuel tank, intake tube, one end of which is placed in the fuel tank with fuel intake from the bottom of the tank and the other end connected to the first pipe, a gas generator mounted in the fuel tank and configured to supply powder gases inside the fuel tank, allows the pressure of the powder gases to submit at the right time in the tray easily Vospominanie fuel, such as gasoline. Execution of the fuel tank optional drawer fuel with cooling, the connection of the second end of the intake tube through destructible at a given pressure of the sealing strip with the first additional tube prevents premature actuation of the device or damage from heat exposure installation. Perform additional unit firing fuel containing the actuator and the charge placed inside a perforated cylinder mounted coaxially within the cylindrical body, connected to the second additional tube, helps to burn in the tray easily Vospominanie fuel, such as gasoline. The invention is illustrated by drawings: - figures 1 and 2 show a side view and a top view of the installation with one pair of optional drawers and ignition of the fuel, respectively; - figure 3 shows a cut additionally what about the feeder fuel; figure 4 shows the device cooling tubes connected to the ignition device; - figure 5 shows an additional device for ignition of fuel. This object is achieved as follows. Inside of the working chamber 1 with the boot box, made with the possibility of overlapping leaves 2 posted: device 3 for fastening the object 4 and at least one fuel manifold 5 with vortex nozzles 6, below the fuel reservoir 5 has at least one tray 7. The ignition device 8 mounted on the wall of the working chamber 1 and is directed into the tray 7. The installation includes a device for supplying fuel, which typically use centrifugal fuel pump (not shown), connected by a pipe 9 with the fuel reservoir 5, and at least one pair of additional feeders 10 and 11 ignition of the fuel, each of which is placed at a given distance (in this example 3-5 m) from the working chamber 1 and connected, respectively, of the first 12 and second 13 additional pipes tray 7. The second additional pipe 13 before ignition device 11 is installed a cooling device 14 of this pipe (in this case in the form of a casing with circulating water). Additional feeder 10 includes a fuel filled (in this example, gasoline 15) topl is wny tank 16, made with cooling, intake tube 17, one end of which is placed in the fuel tank with fuel intake from the bottom of the tank and the other end connected through destructible at a given pressure of the sealing gasket 18 with the first pipe 12. The gas generator 19 is installed in the fuel tank 16 and is arranged to feed the powder gases inside the fuel tank. The accessory ignition fuel 11 contains the actuator 20 and the battery 21, is made from a mixture in predetermined proportions (in this example, 1:1) powder and aluminum powder, placed inside a perforated cylinder 22 mounted coaxially within the cylindrical body 23 connected to the second pipe 13. Does the installation in the following order. Prior experience loaded and installed the necessary number of pairs (determined by the algorithm of thermal loading) additional feeder 10 and 11 ignition of fuel at a distance from the working chamber 1, which excluded them heating up nesankcionirovannaya triggered by thermal radiation. The tray 7 is filled with gasoline. Start the ignition device 8, which ignites the gasoline in the tray 7, and then the flow of the primary fuel (in this example, kerosene) through the vortex nozzle 6 and a reliable ignition of his harasing tray gasoline. Next is the process of thermal loading of the object 4 according to a predetermined algorithm. Heating optional drawers 10 and 11 ignition of the fuel by heat transfer pipes 12 and 13 are eliminated by circulating cooling water around the tank 16 and the cooling device 14 of the pipe 13, respectively. The intake tube 17 one end of which is directed to the bottom of the fuel tank with fuel intake from the bottom of the tank, and a second end connected through destructible at a given pressure of the sealing gasket 18 with the first additional pipe 12, which allows you to divide the cavity of the working chamber 1 and the fuel tank 16 and, thus, eliminates the penetration of fuel vapor in the heating chamber 1, and premature burnout of the fuel. I.e. the duration of operation of the plant for the study of objects at high temperatures does not affect the performance of additional feeders 10 and 11 ignition of fuel. When you re-enable installation electrical signal to actuate the gas generator 19 additional feeder fuel 10. Inside the fuel tank 16 serves powder gases, under pressure of which the fuel destroys the gasket 18 and the pipe 12 enters the tray 7. Then served an electrical signal to actuate the actuator 20 additional ignition device 11, ignited made of MESI powder and aluminum powder charge 21 and the pipe 13 above the tray 7 with gasoline is thrown out of the force of the flame and the burning aluminum powder. This ensures reliable ignition of gasoline in the tray 7. Then again is the main supply of fuel through the vortex nozzle 6 and a reliable ignition of him burning in the tray gasoline. Thus, the invention provides remote ignition of fuel required number of times at any time in the study of objects at high temperatures, which extends the range of control of a thermal field during heat exposure on the object, improving the reliability and safety of operations. 1.
