この発明は、火足を長く遠くへ達するようにすることと
、バーナーの火口に油燃料の不純物等から生じるところ
のカーボンが附着しないように開発された噴射バーナー
に関するものである。[Detailed Description of the Invention] This invention relates to an injection burner that has been developed to allow the flame to reach a long distance and to prevent carbon generated from impurities in oil fuel from adhering to the burner crater. It is.
瓦等の焼物や焼成加工に用いるバーナーで、例えば横穴
状のかまどの奥に火■を到達せしめるには、必然的に火
足の長いバーナーが要求される。A burner used for pottery such as roof tiles or firing process requires a burner with a long flame, for example, in order to make the flame reach the depths of a horizontal furnace.

たが、本発明では安価な重油の使用を希うものである。Conventionally, in order to increase the length of a fire, it was natural to increase the pressure of the supplied air, but in addition, measures were taken to narrow the opening of the fuel cylinder. In this case, the fire nozzle was required to be made of a material with strong fire resistance, and if the material inevitably became brittle, deposits such as carbon would accumulate in that part, which blocked the fire nozzle. For this reason, refined fuel oil such as kerosene has been required, but the present invention prefers to use inexpensive heavy oil.

2 is a combustion tube, 8 is a crater, and since the crater 8 can be constricted, it was specially made of refractory material.

成されている。FIG. 2 shows an embodiment of the injection burner according to the present invention. In the burner, oil fuel is injected together with air into the nozzle 1 and ignited in the combustion tube 2 for combustion. An inner cylinder 3 having a tapered porous wall is provided, and a mechanism for supplying secondary air passing through the inner cylinder 3 from the outside is constructed. In the figure, 4 is a spark plug, 5 is a fuel supply pipe to nozzle 1, 6 is a primary air supply pipe, and 7 is a fuel supply pipe to nozzle 1.
is the secondary air supply pipe. Compressed air is inserted into the secondary air inlet pipe 7, and the outside of the inner cylinder 3 in the combustion cylinder 2 becomes high pressure, so that the secondary air penetrates the porous wall of the inner cylinder 3 and blows out.

ものである。Therefore, if the present invention is carried out, the fire A that ignites the nozzle 1 and burns will be surrounded by secondary air blowing out from the surroundings, and since the inner tube 3 has a tapered shape, the fire A will gradually be narrowed down and will erupt for a long time. The ejection of secondary air surrounding the fire (2) has the advantage of preventing non-combustible materials (carbon, etc.) from adhering to the inner pipe, and extends the life of the burner.
