Due to the suction energy generated by the jet of primary air ejected from the gas nozzle (23), the combustible gas is discharged into the pentieri mixing pipe (20), and the mixed gas (i) passes through the diffusion network (25) and reaches the burner top. Here, the mixed gas collides with the ceiling plate (50), diffuses, swirls in the circumferential direction, is discharged radially from the gas discharge port (43), is ignited, forms a deposit, and also flows into the secondary air pipe (12). , l' collides with the baffle play (64), diffuses into the secondary air flow space (61), and exits the secondary air outlet (62).

されるので混合性に優れると共に。First of all? ! Since the air gas is discharged radially relative to the burner axis, the contact area with the air is larger than that of a gun-type flame, and secondary air is constantly supplied from the bottom of the flame base, so the combustion air This can suppress poor combustion due to insufficient combustion and the generation of CO that accompanies this.The mixed gas that flows into the burner top from the second V, Penchiley Mixture Blue (20) collides with the ceiling plate (50) and diffuses. However, the air and combustible gas are sufficiently stirred here, resulting in excellent mixing properties.

きる。Since the mixed gas is decelerated by collision and swirling, lifting of the flame can be prevented.Fifth, the secondary air flow space (61)' flows into the secondary air flow space (61)' and flows out from the secondary air outlet (62). The next air is the flange part (41) that constitutes the flame mouth part.
It has the effect of cooling down the flame, and reduces the amount of flame caused by the flame becoming red hot.
It is possible to prevent burnout due to scratching phenomenon and abnormal heating.

組合せによってガス吐出口(43J。If installed vertically, the flame will be formed in a radial pattern, which will heat the bottom of the can evenly and close to the can, improving thermal efficiency. In this case, the ceiling plate (50) can prevent combustion condensate from falling into the burner top and causing corrosion.Fifth, the flat plate (44) and the flame hole partition plate (4
5) are stacked alternately to divide the gas discharge port (43) into a large number of small flame holes, and the input per port is set to be small, so combustion is fully stabilized and combustion noise is suppressed. When manufacturing the Plastburner of the present invention, there is a means for setting the flame hole load and increasing or decreasing the number of flat plates (44) and flame hole dividing plates (45) interposed between the gas discharge ports. As a result, a burner with several levels of combustion capacity can be obtained, so common parts can be used instead of manufacturing different models with different combustion capacities, making production management easy and reducing costs. be able to. An example of the design standard is as shown in the table below. Gas discharge port (43J.

用的効果を奏するものである0Since the secondary air discharge port (62)' is provided in an annular shape, it has a flatter vcH compared to conventional products, and there is no need to provide a large diameter cylindrical body called a flame holding tube in the combustion part as in conventional products. It is manufactured in a small size and has practical effects such as fewer restrictions on the design dimensions of one device.
