The invention relates to test equipment and can be used for testing objects, including those containing explosives and toxic substances, at different heat exposure, including fires. The famous setting for the study of objects at high temperatures, is selected as the analogue containing working chamber with boot box, made with the possibility of overlap, the device for heating and fixing of the object (see A.S. USSR №274421, IPC 6 G01N 3/18, publ. 24.06.70 bull. No. 21). The disadvantages of this setup: - the inability to study the complex influence on the object of heating and means of fire; - inability to quickly reduce the temperature of the heating due to the high thermal inertia of the working chamber; - great fuel consumption. The famous setting for the study of objects at high temperatures, selected as a prototype, containing working chamber with boot box, made with the possibility of overlap, placed inside the chamber of the device for heating and fixing the object, the working chamber additionally contains in the upper part of the exhaust pipe, at the bottom of the hatch, equipped with movable flaps, the ignition device, the feeder agregating means inside the chamber, a device for heating is made in the form of at least odnostebelnogo collector with water injectors evaporators, fuel tank, connected with a device for supplying fuel pipe for supplying fuel to the manifold, connected at one end with a device for supplying fuel, and the other with header (see RF patent №2149330 from 24.04.1998,, IPC 7 F27 17/02, G01N 25/00, publ. 20.05.2000,, bull. No. 14). Practice has shown that when working on this unit using a liquid fuel, such as kerosene, after a certain time (the higher the temperature in the chamber, the faster) gradually begin to fade most distant from the inlet fuel manifold vortex nozzle. This leads to loss of control of a thermal field in the working chamber and, accordingly, it impossible to obtain the desired temperature of the temperature field and its uniformity throughout the volume of the working chamber. The reason for the termination of combustion is that, as the movement of fuel in the manifold, it evaporates, goes through extreme injector in the form of vapour and creates air combustible mixture (it should be noted that the nozzles are designed to spray liquid fuel). The task of the invention is to provide a reliable combustion of the fuel in the working chamber by spraying through the vortex injector fuel in a liquid state during any time and at any temperature that is created used fuel type. Technical financial p is tat: reliable combustion of fuel and management of a thermal field in the working chamber during heat exposure on the object.

Introduction to the setting for 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 manifold with a vortex nozzle; a fuel tank connected with a device for supplying fuel pipe for supplying fuel to the manifold, connected at one end with a device for supplying fuel, and the other to the collector, the ignition device, an additional cooling coil with adjustable latch at its output and the fuel temperature sensor, installed at its input, at least one of the pipes to drain fuel from the manifold, one end of which is connected to the upper surface of the fuel manifold side, the anti-Christ. alonei place connecting pipes for the supply of fuel, and the other end connected to the inlet of the cooling coil, the output of which through an adjustable valve connected to the fuel tank, allows you to create the moving speed of the fuel in the reservoir, in which virtually eliminated the formation in the manifold of the fuel vapors, and, respectively, to spray fuel into the working chamber through the vortex nozzle in the liquid state, which, in turn, helps to ensure reliable combustion and thermal field in the working chamber during heat exposure on the object. Supply of vortex injector nozzles, configured to supply fuel to the injector bottom surface of the reservoir, allows, even when a formation of fuel vapor in the header to spray liquid fuel.

Outside of the camera is set to the fuel tank 8 and the pipe 9 and 10 is connected with a device 11 for supplying fuel into the pipe 12 for supplying fuel to the manifold 5. The pipe 12 is connected at one end with a device 11 for supply of fuel, and the other to the collector 5. The system includes a cooling coil 13 controlled by valve 14 at its output and the fuel temperature sensor 17 mounted on its input, the two pipes 15 for removal of fuel from the manifold 5. One end of the tube 15 is connected to the upper surface of the fuel reservoir 5 from the side opposite to the location of the connection pipe 12 for supplying a fuel and the other end connected to the inlet of the cooling coil 13.

The fuel passes through the branches of the manifold 5, part of it is sprayed through a nozzle 6, and the other part passes through the pipe 15, the cooling coil 13, the adjustable valve 14 and then into the fuel tank 8. Pre-adjustable valve 14 is set in position (chosen experimentally)at which the rate of fuel flow through the manifold 5 eliminates the evaporation of fuel in the reservoir 5, without prejudice to the adjustment of pressure in the specified range. Through a nozzle 6 is atomized liquid fuel, which ensures its stable combustion and reliable control of a thermal field in the working chamber 1. In the process of thermal loading of the object 4 controls the fuel temperature at the inlet to the cooling coil 13 by the fuel temperature sensor 17. When approaching the fuel temperature to the boiling point by means of controlled valves 14 increase fuel consumption through a cooled coil 13 and prevents the evaporation of fuel in the reservoir 5.
