Description

[Detailed Description of the Invention] The present invention relates to a cylindrical gas burner that is mainly used in round radiant heaters and includes a combustion tube whose peripheral surface is the combustion surface.

Conventionally, heaters using this type of burner are mainly placed in the center of a room and used to heat the entire area around it, but when there are few people, heat is radiated wastefully in directions where there are no people. This goes against the demands for energy conservation.

The present invention was proposed to solve this problem, and in a gas burner equipped with a combustion tube 2 whose peripheral surface is a combustion surface 1, the internal space of the combustion tube 2 is partitioned in the axial direction of the combustion tube 2. It is partitioned by a plate 3 into at least two chambers 5, 5 on one side and the other side to which gas is supplied through separate mixing tubes 4, 4, and each mixing tube 4 is inserted into each chamber 5, and Divide each mixing tube 4 in half and insert one half 4a into the partition plate 3.
It is characterized by being integrally formed with.

In the illustrated one half 4 of the mixing tubes 4,4
a, 4a were formed into one piece on the partition plate 3 by pressing or other means, and the other half parts 4b, 4b were joined to this by spot welding or other means to form the respective mixing tubes 4, 4. As shown in the first figure, the combustion tube 2 is formed into a cylindrical shape by attaching combustion plates 7 having an arcuate cross section and forming the combustion surface 1 to each circumferential side of a square cylindrical support frame 6. The internal space is divided into two chambers 5, 5 on one side and the other side by an axial partition plate 3 located on the diagonal of the support frame 6, and each chamber 5, 5 is provided with an axially downward direction as shown in the second figure. Insert each mixing tube 4, 4 from
Gas nozzles 9, 9 connected to a gas control unit 8 were provided at the lower inflow ends of each of the mixing tubes 4, 4.

In the drawing, numeral 10 indicates an operator of the control unit 8.

Next, to explain its operation, the control unit 8 can be used to supply gas to one gas nozzle 9 using its operator, to supply gas to the other gas nozzle 9, and to supply gas to both gas nozzles 9, 9.
In the state where gas is supplied to either one of the gas nozzles 9, the outer surface of one of the chambers 5 to which gas is supplied via the corresponding mixing pipe 4. Combustion tube 2 located at
Combustion is carried out on the half circumferential surface of both gas nozzles 9, 9.
When gas is supplied to the cylinder 2, combustion occurs over the entire circumferential surface of the combustion tube 2.

Therefore, combustion can be switched to half or the entire circumferential surface of the combustion tube 2 depending on the usage status of the heater, thereby preventing wasteful heat radiation.

In this way, according to the present invention, the internal space of the combustion tube 2 is partitioned into at least two chambers 5, 5 by the partition plate 3 in the axial direction, and the combustion surface 1 around the combustion tube 2 is divided into each chamber 5, 5. It is divided into multiple corresponding parts in the circumferential direction, making it possible to burn each part separately, and when used in a round radiant heater,
It is possible to freely stop combustion in the surrounding area that does not require heating, which is effective as an energy saving measure, and furthermore,
Since each mixing tube 4 is inserted into each chamber 5, and each mixing tube 4 is divided in half and one half 4a is integrally formed with the partition plate 3, it is possible to reduce the amount of material used, and The mixing tubes 4, 4 can be compactly inserted into the relatively narrow chambers 5, 5, and the internal space can be used effectively, and the holding and positioning of the mixing tubes 4, 4 can be ensured, and the nozzle center and This has the effect of preventing inconveniences such as deterioration of combustibility due to misalignment of the positional relationship.
