Abstract

The invention provides a heat exchange tube and a burner with a spiral flat tube self-preheating device. The heat exchange tube is a twisted spiral flat tube; the spiral flat tube comprises a spiral flat tube main body with a flatly tubular section and a spiral flat tube end connected with the spiral flat tube main body; and the section of the spiral flat tube end is round. The burner at least comprises a smoke chamber, and a heat exchange tube which is used for accommodating a gas to be preheated and arranged in the smoke chamber; and the heat exchange tube is the heat exchange tube provided by the invention. The invention is simple in operation, reliable and stable in running, and higher in heat exchange efficiency.

Description

technical field [0001] The invention relates to the field of industrial heating, in particular to a heat exchange tube and a burner with a self-preheating device for the spiral flat tube. Background technique [0002] Self-preheating burners can be used for direct or indirect heating of industrial furnaces, especially heat treatment furnaces. This type of burner uses the flue gas discharged by itself to preheat the combustion air through a compact heat exchange device, which can ensure the control and uniformity of the temperature in the furnace, and is conducive to improving the heating quality of the product. [0003] At present, the self-preheating burner basically adopts a finned heat exchange device, and its material is heat-resistant cast steel or ceramics. The heat exchange device is usually composed of straight heat exchange tubes and fins arranged on the straight tubes. It has a relatively simple structure and a wide range of applications. The effect is better, bu...
