Product Description

Carbon Steel/Stainless Steel Spiral Finned Tube for Boiler Economizer and Air Preheater
H-type finned tubes are designed for waste heat recovery from flue gas exhaust in power plant boilers, industrial boilers, kilns, and marine power plants. These components maximize heat utilization, improve fuel efficiency, and reduce emissions while serving as enhanced heat exchange elements positioned at the tail of fuel duct systems.
The double H-type finned tube features an innovative separate structure that prevents ash accumulation and gas resistance issues common in spiral finned tubes. Its cantilever beam rib design enhances vibration under pulsed airflow, facilitating effective ash removal.
Key benefits include expanded heating surface for improved heat transfer coefficient and self-cleaning functionality that minimizes smoke dust deposition, blockage, and wear - ensuring extended service life and safe operation of waste heat boilers.
