Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a burner for an oil hot air heater.

BACKGROUND ART A conventional burner for an oil hot air heater is attached to a burner base within the oil hot air heater, and a vaporizer having a nozzle is exposed at the lower part of the burner.

Problems that the invention aims to solve According to the above configuration, the burner for oil hot air heaters that vaporizes and burns oil uses a vaporizer to raise the vaporized oil gas to about 250°C and sends it into the burner. , it is cooled by the secondary air necessary for combustion that passes through the bottom of the burner, and some of it liquefies and accumulates at the bottom of the burner, resulting in abnormal combustion, prolonged digestion time, and odor. There were other problems.

Means for Solving the Problem A cover is provided on the outer periphery of the lower part of the burner, and the cover has a secondary air circulation opening on its side, and the secondary air circulation opening is connected to the top and bottom of the burner constituting the burner. It is located above the joint.

Function The secondary air flow opening is located above the joint between the top and bottom of the burner, and as the secondary air flows above, there is no cooling to the bottom of the burner, so the bottom of the burner can reach temperatures above 150°C. can be maintained. There is therefore no liquefaction of the vaporized gas at the bottom of the burner. Therefore, there is no abnormal combustion, the digestion time is short, and no odor is generated.

Example Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

The configuration of the embodiment is as shown in FIGS. 1 and 2.
Reference numeral 1 denotes a burner, which is composed of an upper burner 2 and a lower burner 3, and the upper and lower burners 2 and 3 are integrated by welding or caulking. 4 is a burner base, which has a secondary air port 5 consisting of a large number of holes. A cover 6 is provided on the outer periphery of the lower part of the burner 1, and the cover 6 has a secondary air flow opening 7 on the side surface, and the burner 1 is sandwiched between the cover 6 and the burner base 4. It is fixed and held using screws 8 and the like. The cover 6 is provided with a secondary air flow opening 7 located above the joining surface of the upper and lower burners 2 and 3. 9 is an inner duct, 10 is an outer duct, 11 is an outer plate, 12 is a louver, 13 is a blower, 14 is a carburetor, and 15 is a nozzle, all of which are well known, so detailed explanations will be omitted. 16 is a stand, and outer plate 1
It is installed at the bottom end of 1.

The operation of this embodiment having the above configuration will be explained.

The petroleum gas ejected from nozzle 15 is 250
It flows into the burner 1 at a temperature of about 0.degree. On the other hand, the secondary air necessary for combustion sucked in by the operation of the blower 13 is sent from the inner lower part of the outer panel 11, passes through the secondary air flow port 7 of the cover 6, and is then sent from the secondary air port 5 of the burner base 4. Spilled out and subjected to combustion. At this time, the secondary air flow opening 7 is connected to the upper and lower burners 2 and 3 of the burner 1.
It opens further upwards, and the flow of secondary air does not pass around the lower burner 3 forming the bottom of the burner 1. Therefore, it is difficult to prevent the bottom of the hanna 1 from being cooled by the secondary air. Therefore, the bottom of the burner 1 is always maintained at a temperature of 150° C. or higher, and the vaporized gas is not liquefied at the bottom of the burner 1.

Effects of the invention: A cover with a secondary air flow opening is provided above the joint between the burner top and the bottom of the burner, and the burner is mounted between this cover and the burner base cover via the joint. By this,
Since vaporized gas does not liquefy and accumulate at the bottom of the burner, abnormal combustion, prolonged digestion time, and odor can be prevented, resulting in improved combustion efficiency and usability. .
