成したものである。In view of the above-mentioned problems, the present invention has developed a burner tile having a combustion chamber whose tip opening is narrowed into a thin plate shape, and a gas ejection hole at the tip. and a pre-mixing burner with primary air blowing holes arranged on both sides of the gas blowing hole to blow out the gas toward the ejected gas, and the pre-mixing burner is arranged in the combustion chamber of the burner tile. At the base of the combustion chamber,
A line flame burner is formed by disposing secondary air ejection holes for ejecting a portion of the combustion air as secondary air.

燃焼するガス炎が板状短炎（１２）となって噴出する。A combustion chamber (3) is formed in the burner tile (1) with the tip narrowed and the burner tip opening (2) at the end thereof made into a thin plate shape, and the rear end side of the burner tile (1) is A gas pipe (4) is inserted approximately in the center of the pipe, and its tip is formed into a T-shape, and branch pipes (4') extend on both sides of this gas pipe (4).
is arranged at the base of the combustion chamber (3) and along the width direction of the combustion chamber (3), and furthermore, a large number of gas injection holes (5) are bored along the entire length of this branch pipe (4゛), Further, a large number of primary air injection holes (6) are provided on both sides of the branch pipe (4'), and primary air is blown onto the gas ejected from the gas injection holes (5) to diffuse it and burn it. The above-mentioned supply air is sent to the air pipe (8) to the air chamber (7) surrounding the gas pipe (4).
), and an air diffusion plate (9) is press-fitted in the middle of the air chamber (7).
) is provided to average the air flow through the air diffusion plate (9), and the secondary air is sent to the primary air outlet (6) as described above, and the gas outlet (5) and the large air outlet (6) )
The combustion chamber (
3), a part of the pressurized air is introduced as secondary air from the secondary air blow-off hole (10) so as to follow the inner wall of the air blower. As a result, a gas flame that is completely combusted by the supply of the secondary air is ejected from the tip opening (2) as a short plate-shaped flame (12).

。Since the high-temperature heating of the object to be heated is performed by direct flame heating using this burner, rapid heating is possible, thus reducing the time and energy loss required to raise and maintain the temperature inside the furnace at a high temperature. In addition, by making the heating flame into a short flame plate shape, we were able to improve the heating temperature distribution and heat transfer characteristics of the long object to be heated. Gas is supplied, and since it is a pre-mixing method, high-temperature combustion is possible by preheating the mixed air and increasing the combustion speed.

効率を上昇させることができる。In addition, because secondary air for combustion is injected into the combustion chamber wall of the burner tile in a side laminar flow, unnecessary temperature rise of the burner tile can be suppressed and the combustion efficiency of the flame ejected from the tip opening can be increased. be able to.
