Add Heat Exchange Area and Reduce Tube Number H Type Finned Tube for Better Efficiency

Add Heat Exchange Area and Reduce Tube Number H Type Finned Tube for Better Efficiency

Product Description

The H-type finned tube is a strengthened heat exchanger element arranged at the tail of the system flue in order to recover the exhaust waste heat of power station boilers, industrial boilers, industrial kilns, ship power units, etc., and effectively improve the utilization rate of fuel. In terms of structural design, the H-type finned tube adopts a separate structure for the ash-prone parts of the tube, which overcomes the shortcomings of the spiral fin tube that is easy to accumulate dust, plug ash, and gas resistance, and it is an improved product of the spiral finned tube. In addition, the ribs of the fin tube form a cantilever beam structure, and under the action of pulsed air flow, the ribs vibrate to be more conducive to the treatment of ash staining.

Advantages

1. Add the heat exchange area and reduce the number of tubes, also increase the fume flow section area to reduce the fume speed and abrasion.
2. H type fin tube can be made to double H type fin tube, high rigidness to fit long tube row.
3. H type fin economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.
4. With straight channel to gain the best ash-blowing effect.
5. The compact structure to reduce the weight and reduce the manufacturing cost.

Constructions

1.Finned Tube Heat Exchangers consist of a shell and finned tubes assembly.

2.Fins are used to increase the effective surface area of heat exchanger tubing.

3.Finned tubes are used when the heat transfer coefficient on the outside of the tubes is appreciably lower than that on the inside;as in heat transfer from a liquid to a gas,vapor to a gas ,such as steam to air heat exchanger, thermic fluid to air heat exchanger, when an extended surface is needed on only one fluid side or when the operating pressure needs to be contained on one fluid side.

Technical parameter

Medium air, flue gas, thermal oil, water, brine, refrigerant, etc.
Temperature standard heat exchanger to 560 ° C by special materials can be higher
Pipe materials carbon steel, stainless steel, alloy or special materials
Ribs materials carbon steel, stainless steel, non-ferrous metal, alloy or special materials
Thermal insulation &Surface treatment according to customers specification

Features

1. The equipment body can be designed into many modules to ensure the long term and stable running;

2. Compact structure which can enlarge the heat exchanging area in order to add the heat transfer area and less leakage

3. Improve the heat transfer efficiency

4. Structure arrangement: In line or staggered arrangement

1.Our products can be modified according to our customers' needs and the situation.
2.we design and manufacture safe,reliable and efficient H-fin tubes.HD BOILER has also completed stand-alone product quality assurance systems.
3.Production of H-fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space.
