Basic introduction of spiral finned tube Spiral finned tubes have been widely used in heat recovery of boiler economizers, air preheaters and waste heat boilers, as well as heat exchange equipment in various fields such as chemical industry and pressure vessels. The capacity of the unit used in the boiler is also increased from small [...]
What is finned tubes What's the matter with finned tubes A finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added on the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, so as to [...]
The advantages of countercurrent heat transfer in finned tube heat exchangers Finned tube heat exchangers's Large logarithmic evaluation temperature difference: The calculation shows that under the same inlet and outlet temperature, the logarithmic average temperature difference in countercurrent flow is always larger than the temperature difference when the two fluids flow together. The larger the [...]
Material of copper finned tube and carbon steel finned tube Classification of carbon steel pipes Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes. Cold-rolled (dial) [...]
What is finned tube heat exchanger The finned tube heat exchanger achieves the purpose of enhancing heat transfer coefficient by adding fins to the ordinary base fin tubes, and can have a heating effect. When heating is required, it can use high-temperature water, steam or high-temperature heat transfer oil to heat the air. When cooling [...]
Finned tube working principle and application What principles should we follow when we use finned tubes for heat transfer? (1) If the heat transfer coefficients on both sides of the tube are very different, finned tubes should be installed on the smaller side. (2) If the heat transfer coefficients on both sides of the tube [...]
