The combustion-supporting air control element comprises an electric regulating valve 15 and a combustion-supporting air cut-off valve 8.
As shown in fig. 1-2, the gas supply system is mounted on one side of the frame 9. Wherein, the external gas of one end of gas pipe fitting 10, the other end is connected to burning rifle 4. Along the gas pipe 10, a gas inlet valve 16 (see also fig. 3), a gas pressure regulating valve 1, a pressure gauge 17, a gas proportional regulating valve 2, a gas cut-off valve 6, a pressure sensor 18 and the like are sequentially installed. Wherein, gas admission valve 16 can be manual ball valve, and gas pressure regulating valve 1 can be transferred to 50mbar with gas pressure, and manometer 17 is used for showing gas pressure, and gas proportional control valve 2 is used for adjusting the gas size according to the size of combustion-supporting wind automatic proportional control, and gas trip valve 6 is the motorised valve that is used for cutting off and opening the gas, and pressure sensor 18 is then used for measuring the pressure of gas. It should be noted that the order of installation of these components can be adjusted, and certain components can be added or subtracted as necessary as long as the function of controlling the gas can be achieved.
The combustion fan 7 is mounted at the bottom of the frame 9. The combustion fan 7 may be a centrifugal fan. Combustion air generated by the combustion fan 7 is sent to the combustion lance 4 through the combustion air pipe 11. Along the combustion-supporting air pipe fitting 11, a combustion-supporting fan 7, an electric regulating valve 15, a combustion-supporting air cut-off valve 8, a pressure gauge 19 and other components are sequentially installed. The electric regulating valve 15 is an electric butterfly valve capable of electrically regulating the size of the combustion-supporting air, the combustion-supporting air cut-off valve 8 is an electric valve for cutting off and opening the combustion-supporting air, and the pressure gauge 19 is used for displaying the pressure of the combustion-supporting air.

The combustion lance 4 is fixedly mounted on the top of the frame 9 and is connected to a gas pipe 10 and a combustion air pipe 11. The combustion-supporting air and the gas fed by the gas pipe fitting 10 and the combustion-supporting air pipe fitting 11 are mixed and combusted, ignition is realized through an ignition needle in the combustion gun 4, and flame detection is carried out through a flame detector in the combustion gun 4 after ignition.
An electrical control box 5 is installed on the other side of the frame 9, and electrical control components are integrated in the electrical control box. The electric control box 5 realizes automatic control of the gas control element and the combustion-supporting air control element through a combustion controller arranged in the electric control box, thereby realizing the functions of safe ignition, fault alarm, fault interlocking control, continuous adjustable of large and small fire and the like of the combustion gun 4.
Attention is now directed to fig. 3, which illustrates a schematic diagram of the operation of a combustion gun test stand for a uniform temperature furnace according to an embodiment of the present invention. As shown in fig. 3, after the gas inlet valve 16 is manually opened, gas enters the gas pressure regulating valve 1 from the inlet, the gas pressure is reduced to 50mbar, and then the gas enters the gas proportional regulating valve 2. After the ignition program is started through the electric control box 5, the combustion-supporting fan 7 is started, and then the combustion-supporting air adjusting valve 15, the combustion-supporting air cut-off valve 8 and the fuel gas cut-off valve 6 are opened in sequence.

The pressure sampling pipe 12 may be a narrow pipe for introducing the pressure of the combustion air into the gas ratio adjusting valve 2 for use. The gas proportion regulating valve 2 opens a gas channel according to a certain proportion according to the pressure of the combustion-supporting air so as to ensure that the gas and the combustion-supporting air enter the combustion gun 4 according to a set proportion. After the gas and the combustion-supporting air enter the combustion gun 4, the ignition needle in the combustion gun 4 is discharged and ignited under the control of the combustion controller, and the flame detector in the combustion gun 4 starts to work under the control of the combustion controller after ignition. If flame is detected, the flame detector generates a stable electric signal to the combustion controller to form closed-loop feedback, the whole device operates normally, gas is stably combusted at a combustion gun mouth, and at the moment, the size, the rigidity, the shape and the length of the flame can be adjusted by adjusting the valve opening of the combustion-supporting air adjusting valve 15 and the proportion knob of the gas proportion adjusting valve 2. If the flame detector does not detect flame, no electric signal is generated, and the combustion controller immediately outputs an alarm signal and immediately cuts off gas.
In practical use, the working flow of the off-line test bed is as follows:
starting up operation:
1. opening a gas inlet valve;
2. opening a working power supply of the electric control box;
3. starting a combustion fan control button;
4. when the combustion fan works without abnormal phenomenon, the combustion control button is started again, at the moment, the combustion controller starts to work, and the safe combustion is finally realized through the procedures of ignition, air supply, flame detection and the like through a certain procedure. At the moment, the shape and the size of the flame can be changed by adjusting the opening of the combustion-supporting air adjusting valve and the knob of the gas proportion adjusting valve;
5. when the combustion controller receives a signal which is not beneficial to combustion (such as ignition failure, unstable air pressure, circuit problem) and the like, the combustion controller immediately turns off the gas and sends out an alarm signal.
6. If the combustion controller gives an alarm, the combustion controller can continue to work only by manually resetting the combustion controller by an operator after the fault is solved.
(II) shutdown operation:
1. closing a combustion control button;
2. closing a combustion-supporting fan button;
3. turning off a power button;
