The twisted sheet tube section is installed in the furnace tube of the radiant section of the cracking furnace, the flow form of the fluid in the tube changes from a plug flow to a swirling flow, which forms a strong scouring effect on the inner wall of the furnace tube, greatly reduces the thickness of the boundary layer, and increases the furnace tube in the radiant section. The overall heat transfer coefficient reduces the temperature of the furnace tube wall, reduces the coking rate, prolongs the operation period of the cracking furnace, and reduces the energy consumption.
