The coil heater is a type of heat exchanger developed based on the introduction and absorption of international heat exchange products from the 1980s. This product is novel, easy to assemble, easy to maintain, and has good performance.
The heating element of this exchanger adopts a suspended floating coil structure. During the heating process, due to the centrifugal force of steam inside the coil, the coil bundle generates high-frequency vibration, which destroys laminar heat transfer and generates high heat transfer capacity. At the same time, due to the cantilever free end of the coil, it expands and shrinks freely, generating high-frequency vibration, causing alkaline attachments to automatically leave the pipe wall, forming an automatic descaling characteristic.

Structural Features
The coil heater is also a boiler feedwater heating device. This heater replaces the bulky high-pressure water chamber and tube plate in the original "tubular" or "U-shaped tubular" heaters with two main pipes, greatly facilitating manufacturing and maintenance work, and reducing leakage points. In addition, due to the same material and small difference in wall thickness between the riser and heat exchange tube, their welding performance is significantly better than other types. In addition, the spiral tube has good elasticity and does not generate temperature difference stress, so the possibility of heat exchange tube joints cracking will be much lower than other types of heaters.
Optimized Design
Replaces bulky high-pressure water chambers with two main pipes, simplifying manufacturing and reducing leakage points.
Stress Prevention
Spiral tubes offer excellent elasticity, avoiding temperature difference stress and reducing the risk of joint cracks.
Due to the use of spiral tubes in the heat exchange tube, the high-pressure water inside the tube is always in a turbulent state without a stagnation layer. Therefore, its heat transfer efficiency is significantly higher than other types, and its efficiency can be improved by 10% compared to the "U-shaped tube" high-pressure heater. In addition, high-pressure water in turbulent state is less prone to scaling on the pipe wall, reducing thermal resistance and cleaning workload, which can extend the service life of the equipment and greatly improve the economic benefits of the user.
Frequently Asked Questions
What is a coil heater and its primary application?
A coil heater is a modern heat exchanger developed based on advanced international heat exchange technologies. It serves as an efficient boiler feedwater heating device, characterized by its ease of assembly, low maintenance, and outstanding operational performance.
How does the suspended floating coil structure enhance heat transfer?
The suspended floating coil structure utilizes the centrifugal force of steam inside the coil to generate high-frequency vibration. This vibration disrupts the laminar heat transfer boundary layer, resulting in high heat transfer capacity with a coefficient (K) of ≥ 3000W/m²·℃.
How does the automatic descaling mechanism work?
The cantilever free end of the coil allows it to expand and contract freely during operation. This movement generates high-frequency vibrations that cause alkaline attachments and scale to automatically detach from the pipe wall, maintaining optimal performance.
What structural improvements reduce the risk of leakage?
By replacing traditional, bulky high-pressure water chambers and tube plates with two simplified main pipes, the design significantly reduces potential leakage points. Additionally, matching materials and wall thicknesses between the riser and heat exchange tube improve welding performance.
Why does the spiral tube design offer higher efficiency compared to U-shaped tubes?
The spiral tube design ensures that high-pressure water inside the tube remains in a constant turbulent state without forming a stagnation layer. This increases overall heat transfer efficiency by 10% compared to traditional U-shaped tube high-pressure heaters.
How does turbulent flow affect maintenance and equipment life?
The turbulent flow of high-pressure water prevents scale accumulation on the pipe walls. This minimizes thermal resistance, reduces cleaning and maintenance workloads, extends the overall service life of the equipment, and increases economic benefits.
