Abstract

PURPOSE:To enable to supply gas being smoothed in its flow and having uniform density to a flame hole part by installing a smoothing plate in such a manner that burner plates having symmetrical forms and fuel paths are overlapped and the smoothing plate having a number of holes is installed under the flame hole part placed at the top of a unit and enables gas to flow uniformly to the flame hole part. CONSTITUTION:A burner unit is composed of overlapped burner plates 1, 2 having fuel paths and thereon a flame part 3 is placed and also a smoothing plate 7 is placed under the flame hole part 3. In this smoothing plate there are a number of holes 8 of which sizes and pitches become smaller and wider one after another respectively from direction A to direction B. Namely, gas passing through the fuel path 6 from a inlet of the burner unit 5 is enabled to flow in uniform density by the sizes and pitches of holes 8 in the smoothing plate 7 before being introduced into the flame hole part 3 and then is introduced into the flame hole part and also gas is smoothed in the vertical direction as passing through the holes 8.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the construction of a burner unit for burning gas or vaporized fuel.Prior Art The construction of a conventional burner of this type is shown in FIGS. 3 and 4. It was structured like this. An example will be described below with reference to this drawing. That is, the left and right pairs of overlapping play) Ll, play) R2° from the flame mouth part 3 to the plate 1. The plate R2 is machined for a passage for the fuel 4, and the plate Ll and plate R2 are overlapped to form a passage for the fuel 4, and a flame port 3 is also formed on the upper part of the plate Ll and the plate R2. A burner unit was constructed by providing a burner unit.

The operation of the burner unit configured as described above will be explained below.

First, the supplied fuel 4 entered the burner unit together with the surrounding primary air from the inlet 5 of the burner unit, passed through the gas passage 6, was led to the flame port 3, and was combusted.

Problems to be Solved by the Invention However, in the above configuration, the gas that has passed through the gas passage of the burner plate is guided to the flame port at once.
The gas was not evenly distributed over the vertically elongated flame opening, resulting in uneven gas concentration at the flame opening, causing lift and poor combustion.

The present invention solves these conventional problems and contributes to improving zipper performance. -Means for Solving the Problems The burner unit of the present invention is constructed such that a rectifying plate is provided below the burner port so that the gas that has passed through the burner plate is uniformly guided to the burner port.

Function: The rectifying plate provided in the burner unit of the present invention changes the opening degree of the opening provided in the plate to allow gas to flow uniformly, and ultimately the gas concentration at the flame opening is adjusted. is made to be uniform.

EXAMPLE Hereinafter, a burner unit according to an example of the present invention will be described with reference to the drawings. In addition, the same reference numerals are attached to the same functional parts as in the above-mentioned conventional example.

In FIGS. 1 and 2, a burner plate L and a burner plate R2 each having a fuel passage are stacked one on top of the other to form a burner unit, and a flame port 3 is provided on the upper part of the burner unit.

Furthermore, a current plate 7 is provided below the flame port 3. This current plate 7 has a plurality of apertures 8, and the size and pitch of the apertures 80 gradually decrease from the entry direction toward the B direction, and the pitch increases.

That is, the gas 4 that has passed through the fuel passage 6 of the burner plate from the inlet 6 of the burner unit becomes uniform in gas concentration depending on the size and pitch of the openings 8 of the baffle plate 7 before being guided to the flame port 3. It leads to the flame mouth. Furthermore, when passing through the opening 8, the gas is rectified in the vertical direction.

Effects of the Invention As described above, the burner unit of the present invention is able to supply gas to the flame port with a flow rectified by the action of the rectifying plate provided below the flame port and with a uniform concentration.

Therefore, the lift combustion and the performance characteristics of CO7CO2 are improved, and the performance of the main body of the device is also improved, which is extremely effective in practice.
