Abstract
The invention provides an immersed heating tube of an aluminum alloy gas stove. The immersed heating tube of the aluminum alloy gas stove comprises a combustor. The combustor comprises a combustion tube and an ejection hole. The immersed heating tube is characterized in that a radiant tube fixedly sleeves the periphery of the combustion tube; an inner cavity of the radiant tube is fixedly connected with a flame flow guiding tube; an upper tube opening of the flame flow guiding tube is opposite to the ejection hole; a circular gap is formed between the ejection hole and the upper tube opening of the flame flow guiding tube; and a flame concentration area is formed between a lower tube opening of the flame flow guiding tube and the bottom of the radiant tube. According to the technical scheme, the immersed heating tube can be immersed in molten aluminum when heating the molten aluminum; and the problems of over burning on surfaces, large oxidation burning loss, low molten aluminum quality, hydrogen absorption and the like in the traditional heating mode are effectively avoided.
