Auto-Welding H-Type Boiler Fin Tube Economizer For Waste Heat Energy Industrial
Product Description
H finned tube is called square finned tube, there are two types of H finned tube, one is a single tube, usually called square finned tube, the other is a double tube, usually called rectangular finned tube. And according to customer requirements manufacturing. Due to its rectangular shape, it provides a larger surface area than spiral finned tubes. Because of the larger surface area available, these finned tubes are primarily used in air heating applications to reduce the overall size of the equipment.
The fusion rate between the H-shaped finned tube and the steel tube is as high as 95% or more, the contact thermal resistance is small, and the thermal conductivity is good. Because the airflow between the heat exchange tube bundles is similar to the tandem flow characteristics, there is less dust accumulation on the heat exchange surface during operation, and the fins are more uniformly scoured. The effective utilization rate of the H-shaped fin expansion area is higher than that of the spiral finned tube, and the overall heat transfer efficiency It is about 10% higher than spiral finned tube bundle.
H-shaped finned tubes have a high area expansion rate, less dust accumulation, and high heat transfer efficiency. In the case of equivalent heat transfer capacity, the heat exchanger can occupy the smallest space, and can minimize high-grade materials (ie, pressure tubes) The amount of use, and more use of low-grade materials, (fins). For new engineering projects, the height of the heat exchanger arrangement can be reduced, the overall weight is greatly reduced, the load of the suspension system is reduced, and the overall cost is reduced; for the renovation project, as much heat exchange area as possible can be arranged in a limited space to reduce the exhaust temperature , Improve the efficiency of waste heat recovery or increase the maintenance space for easy maintenance.
