<p>The present invention relates to a spray nozzle for emitting flame using oxyhydrogen gas for spraying oxygydrogen gas, which is a mixture of oxygen and hydrogen, and generating a flame. The spray nozzle of the present invention comprises: a main frame; a passage; and a spray hole. The main frame is combined with a supply line for supplying oxyhydrogen gas, which is a mixture of oxygen and hydrogen, and has an accommodating space for temporarily accommodating the oxyhydrogen gas supplied from the supply line inside. The passage is formed by penetrating the main frame and connected to the accommodating space, and, the oxyhydrogen gas conveyed from the accommodating space flows in the passage. The spray hole is formed to be connected to the passage, and through the spray hole, the oxyhydrogen gas conveyed from the passage is sprayed to the outside. The spray hole has a rectangular cross-section along the flowing direction of the oxyhydrogen, and is formed to be tapered for the cross-section to be larger in the parts farther from the passage and closer to the outside. The spray nozzle has two spray holes which are placed to cross each other.</p> |
