Abstract

PURPOSE:To save energy in the maintenance work by installing a nozzle for spraying and an ignition plug at a part replacing section and at the same time constituting the part replacing section so s to be freely mounted and dismounted to the main body with the nozzle and ignition plug installed to the part replacing section. CONSTITUTION:A gun type burner 1 is mounted to a heat exchanger 6 of a hot water supplier, etc. by means of bolts 7, etc., and combustion oil is supplied to a nozzle 4 from an oil supply route 8 and the oil is sprayed from its injection opening 9. The oil spray is ignited by the discharge of an ignition plug and burned. Since in the case of maintenance such as inspection, repair, etc. a part replacing section 3 is freely mountable and dismountable to the main body with the nozzle 4 and the ignition plug 5 installed, the nozzle 4 and the ignition plug 5 can be dismounted from burner main body 2 simply by removing the part replacing section 3 from the main body 2. And, if the maintenance work such as inspection, part replacing, etc. is completed, the burner can be recovered to the state in which it can be used when the part replacing section 3 is mounted to the burner main body 2 with the nozzle 4 and ignition plug 5 installed to the part replacing section 3. With this arrangement the energy can be saved in the maintenance work of a burner.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a gun-type burner that sprays and burns fuel oil such as kerosene from a nozzle.

(Prior Art) As a conventional gun type burner, there is one shown in FIG. 3, for example. This burner a ignites and burns the oil sprayed from the injection port C into the oil spray nozzle b by the discharge of the spark plug d. It is pressurized by an electromagnetic pump g and supplied to the nozzle b via the supply yarn path f.

Such a burner a is generally used by attaching it to a heat exchanger such as a water heater using, for example, a pol), but the nozzle b and spark plug d are relatively easy to break down, so they should not be inspected or repaired. There are many opportunities to remove these from burner a, and in such cases, first remove the entire burner a from the heat exchanger, then disassemble it and inspect nozzle b and spark plug d. Or they are performing maintenance such as repairs.

(Problems to be Solved by the Invention) As mentioned above, when performing maintenance such as inspecting or repairing the nozzle b or spark plug d, which are relatively prone to failure in the conventional burner a, the entire burner a must be replaced with a heat exchanger, etc. To install it, you have to remove it from the object and disassemble it, which is troublesome and time-consuming.

The present invention aims to solve such problems.

Note that in FIG. 3, reference numeral j indicates a fan motor, k indicates an igniter, and l indicates an oil strainer.

(Means for Solving the Problems) The means for solving the problems described above will be explained based on FIGS. 1 and 2 corresponding to the embodiments.

The gun type burner 1 of the invention has a parts replacement part 3 formed in a part of the main body 2, and an oil spray nozzle 4 in the parts replacement part 3.
In addition to installing the nozzle 4 and the spark plug 5, the parts replacement part 3 is configured to be detachable from the main body 2 with the nozzle 4 and the spark plug 5 installed.

(Function and Examples) When in use, the gun type burner l of the present invention is attached to a heat exchanger 6 of a water heater or the like with bolts 7, etc., and fuel oil is supplied from the oil supply line 8 in the same way as in the conventional case. The fuel is supplied to the nozzle 4 and sprayed from the injection port 9, and is ignited and combusted by the discharge of the spark plug 5.

However, the nozzle 4 and spark plug 5 are relatively easy to break down, and therefore it is often necessary to remove them from the burner body 2 for maintenance such as inspection and repair. The parts replacement part 3 can be attached to and removed from the main body 2 with the nozzle 4 and spark plug 5 installed, so simply by removing the parts replacement part 3 from the main body 2, you can easily replace the nozzle 4 and spark plug 5 with the burner main body 2. It can be removed from. After maintenance work such as inspection and parts replacement is completed, the nozzle 4 and spark plug 5 are installed in the parts replacement part 3 again, and the parts replacement part 3 is attached to the burner body 2, and it is ready for use. can be recovered.

An appropriate structure for making the parts replacement part 3 detachable from the burner body 2 may be a structure in which the parts replacement part 3 is attached to the burner body 2 using screws 10 or the like.

(Effects of the Invention) As described above, the gun type burner of the present invention allows inspection and repair of the nozzle and dot plug, which are relatively prone to failure, while the burner body remains attached to the heat exchanger, etc. This has the effect of saving labor in burner maintenance work.
