Product Description:

Finned Tube Heat Exchangers is a type of heat exchanger design that uses plates and finned chambers to transfer heat between fluids. It is often categorized as a compact heat exchanger to emphasise its relatively high heat transfer surface area to volume ratio.

Applications :

The cost of Fin heat exchangers is generally higher than conventional heat exchangers due to a higher level of detail required during manufacture. However, these costs can often be outweighed by the cost saving produced by the added heat transfer.
Fin heat exchangers are generally applied in industries where the fluids have little chances of fouling. The delicate design as well as the thin channels in the fin heat exchanger make cleaning difficult or impossible.

Reheaters and superheaters are a set of tubes located in the boiler. Steam from the water walls passes to the superheaters where it is heated above its saturation temperature until the maximum required operating temperature is achieved. The superheated steam then flows through the main steam piping to the high-pressure turbine. Exhaust steam from the high-pressure turbine is guided to the boiler for reheating and from there to the intermediate and low-pressure turbines. High reheating temperatures improve the output and efficiency of a power plant.

Product Introduction of Spiral fin tube
Advantages of Spiral fin tube:

The H-finned tube is the main heat exchange component in the whole exhaust gas boiler, and the H finned tube has the following advantages.

1. Excellent wear resistance
The H finned tube heat exchanger is arranged in line, and the H fins separate the space into several small areas, which have the effect of equalizing the air flow, comparing to the smooth tube heat exchanger with the staggered arrangement and the spiral finned heat exchanger And so on, in the same other conditions, the wear life is higher 3~4 times.

2. Fouling reduced
The formation of fouling occurred in the dorsal side and windward side of the tube. The staggered arrangement of the tube is easy to flush the tube bundle, the fouling at back side is less. It has a good self-cleaning function at the appropriate wind speed. On both sides of the H finned tube are formed straight channel, soot, it can get the best soot effect while adopting soot blower.

3. Reduce the resistance of exhaust gas
As the H fins form straight channels on both sides, and the spiral angel of the spiral fins steer the direction of the airflow, the fins are prone to fouling and have a greater flue resistance than the H fins. Therefore, the use of H-finned tube can reduce the wind resistance, reduce the fan operation and investment costs.

Spiral fin tube economizer is a kind of boiler parts, to have two steel circular symmetry to be welded on fluorescent tubes to form ins positive shape much like letter "H", so-called H-fin tube. H finned tube economizer widely used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.

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

Features

With the artistic appearance and accurate size, the advance process for bending tube and welding, the first rate test equipment and sophisticated technology.

Specifications
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.
