The air supply means may be an air supply hose H connected to the end of the air injection nozzle 200 and a compressor connected to the end of the air supply hose H to supply air have.

Hereinafter, a process of testing the leakage of the burner gun 10 using the burner gun leakage test apparatus according to the present invention will be described. 4 is a plan view showing a state in which the burner gun leakage test apparatus according to the present invention is inserted into the water tank in combination with the burner gun.

First, the chamber 100 is engaged with the body portion 11 of the burner gun 10. [ At this time, the first air supply plug 110 provided in the chamber 100 is inserted into the fuel inlet 11a in a forced fitting manner and the second air supply plug 120 is inserted into the steam inlet 11b in a forced fitting manner. . An air supply hose H connected to the compressor is connected to the air injection nozzle 200.

When the connection of the burner gun 10 and the chamber 100 is completed, a water tank 1 in which the burner gun 10 can be accommodated is prepared and the water is supplied to the water tank 10 to a depth at which the burner gun 10 and the chamber 100 can be filled.

In this case, the length of the rectangular annular shape in the major axis direction may be larger than the combined width of the chamber 100 and the body part 11. For example, the clamp 310 may be formed of a rod having a circular cross-sectional shape, and one of the two shortening portions may be provided with a block 311 having a screw hole 311a formed therein.

Meanwhile, the clamp 310 may be rotatably connected to the chamber 100. For example, the hinge portion 130 is provided on the opposite side of the surface of the chamber 100 on which the first air supply plug 110 and the second air supply plug 120 are provided, and the hinge portion 130 It is possible to connect the short axis portion without the block 311 among the two short axis portions of the clamp 310 to be rotatably connected to the chamber 100. When the clamp 310 is configured to be rotatable in the chamber 100 as described above, the clamp 310 is rotated to the opposite side of the first surface of the chamber 100, The chamber 100 can be easily coupled.

The pressing rod 320 is inserted into the block 311 disposed at the short axis portion opposed to the body portion 11 when the chamber 100 of the long and short axis portions of the clamp 310 is coupled to the body portion 11 Can be combined. For example, the pressure bar 320 may include a screw portion 321 screwed to the block 311 and a handle portion 322 formed to extend vertically from the rear end of the screw portion 321.

When the pressing rod 320 is further screwed to the block 311 and the front end of the pressing rod 320 is further tightened to the block 311 in a state where the front end of the pressing rod 320 corresponds to the body portion 11 of the burner gun 10, The chamber 11 is pressed toward the chamber 100 and the chamber 100 is pulled toward the body part 11 so that the body part 11 and the chamber 100 can be very tightly coupled.

The apparatus for testing a burner gun according to the present invention includes a first air supply plug 110 and a second air supply plug 120 which are forcibly fitted into a fuel inlet 11a and a steam inlet 11b of a burner gun 10 And the chamber fixing member 300 can be used to firmly couple the chamber 100 and the body portion 11 of the burner gun 10 to each other. Thereby, there is no problem that air leaks from the connection part of the body part 11 of the burner gun 10 and the chamber 100 when the air is injected into the burner gun 10.

In addition, it is possible to easily check whether the burner gun 10 leaks by checking the occurrence of bubbles in water by supplying air into the burner gun 10 with the burner gun 10 positioned in the water. Accordingly, it is possible to confirm whether the burner gun used for a long period of time has leaked or not and whether the burner gun has been leaked or not, and it is possible to quickly and accurately confirm whether the used burner gun is in need of maintenance and whether the maintained burner gun is normal or refurbished. This makes it possible to quickly perform the maintenance of the burner gun 10 and solve the problem of unstable combustion of the boiler, that is, the combustion facility due to the failure after the maintenance of the burner gun, thereby improving the operation and reliability of the stable combustion facility.

The description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the invention.
