Finned tube heat exchanger is mainly composed of finned tubes. Finned tube is based on the ordinary light tube with fins to increase the heat exchange area and improve the heat exchange efficiency. This kind of heat exchanger has the following significant features:
High-efficiency heat transfer: the increase of fins greatly expands the heat transfer area, which enables the heat to be transferred from hot fluid to cold fluid more quickly, especially suitable for waste heat recovery, which requires high-efficiency heat transfer.
Compact design: under the same heat transfer capacity, the finned tube heat exchanger is relatively small in size, which saves installation space and is convenient to be arranged in waste heat boilers and other equipment.
Strong adaptability: able to adapt to different temperatures, pressures and flows of waste heat media, with good reliability and stability.
In the waste heat boiler, high temperature flue gas and other waste heat media through the finned tube heat exchanger, the heat is transferred to the working fluid (usually water or steam) inside the tube through the fins and tube wall. After the working fluid is heated, it can be used for power generation, heat supply and other purposes, thus realising the recycling of waste heat.
Industrial field: In iron and steel, metallurgy, chemical industry, cement and other industries, a large amount of high-temperature exhaust gas and waste heat can be recovered through the finned tube heat exchanger for waste heat boiler, which can be used to preheat the air, generate steam or power generation, reducing the energy consumption and production costs of enterprises.
Power industry: thermal power plant boiler exhaust contains a large amount of waste heat, the use of finned tube heat exchanger can be recovered from this part of the heat, improve the energy efficiency of the power plant.
Other fields: such as waste incineration, geothermal use and other fields, finned tube heat exchanger also plays an important role.
