Description

Technical Field

[0001] The utility model relates to the technical field of water jacket furnaces, in particular to a novel spiral tube water jacket furnace. Background Art

[0002] The water jacket furnace is an indirect heating device that uses water as the heat transfer medium. The water jacket furnace is composed of a cylinder, a smoke pipe, a gas coil and other accessories. The gas coil and the inlet and outlet of the cylinder are sealed with packing, and the tightness is adjusted by the packing gland. The water jacket furnace is filled with water through a water tank. The pressure inside the water jacket furnace is normal pressure. A thermometer jack is welded on the water jacket furnace cylinder and a water level gauge is installed to control the operation of the water jacket furnace. The water jacket furnace cylinder is supported by a saddle support, and refractory materials are laid on the cylinder for insulation. The heating principle of the water jacket furnace is that the high-temperature flame ejected by the natural gas burner directly heats the smoke Fire tube, high-temperature flue gas flows backward, enters the smoke box through the smoke outlet pipe, and is then discharged into the atmosphere through the chimney. However, the water near the fire tube and the smoke outlet pipe rises due to the decrease in density after being heated, and its temperature drops after contacting with the gas coil and transferring heat, and then sinks due to the increase in density, and then rises again after being heated. This cycle continues to heat the natural gas in the gas coil to achieve the purpose of increasing the temperature of the natural gas flow. Since the form of the existing gas coil directly affects the heat exchange effect and the convenience of connection and maintenance, it is necessary to perform connection and maintenance operations on the gas coil.

[0003] In the related art, during the use of the water jacket furnace, a straight tube arrangement is generally used for connection and heat exchange operations, and the straight tube is connected to the external pipeline for connection and maintenance, so as to use it.

[0004] However, during the current use of water jacket furnaces, due to the arrangement and connection method of straight pipes, multiple straight pipes need to be installed and connected, which consumes the internal space of the water jacket. In addition, during the flue gas emission process, dust, tar and other impurities will adhere to the inner wall of the chimney, affecting the heat exchange effect of the water jacket furnace connection and the convenience of smoke exhaust cleaning.
