Air preheater, also called air preheater for short, is a kind of preheating equipment to improve the heat exchange performance of boiler and reduce heat loss. the function of the air preheater is to transfer the heat carried by the flue gas discharged from the tail flue of the boiler to the air before entering the boiler through the radiator to preheat the air to a certain temperature.
the three-dimensional fin is processed by cutting the inner and outer walls of the metal tube, which is not only a new processing technology, but also a technology to enhance heat transfer. the heat transfer effect of this type of heat exchange tube is 2.5-6 times higher than that of ordinary smooth tubes. Three dimensional finned tube is a new generation of non continuous enhanced heat transfer tube composed of fins. the fin erosion caused by three-dimensional fluid flow is better than that caused by two-dimensional fluid flow, and it has stronger anti fouling ability and heat transfer ability. Integrated processing, no contact thermal resistance; The tube wall temperature can be adjusted by adjusting the number, height and layout of fins, which is conducive to reducing the risk of low-temperature corrosion; The spacing of heat exchange tubes can be appropriately increased, which is conducive to ash removal and maintenance and tube replacement; The heat transfer inside and outside the tube is enhanced at the same time, which makes the heat exchanger more efficient and compact. It is an efficient heat transfer element with excellent heat transfer performance. In terms of processing technology, this technology breaks through the current international processing technology that can only process copper, aluminum and other soft metal materials, and expands the materials to steel, stainless steel, titanium and other ductile metals, so that heat exchangers in all industries can use this type of finned high efficiency heat exchanger.
