H Fin tube, boiler replacement parts,Boiler heat exchange parts
H fin tube is used to recover the gas waste heat of the power
station boiler, the industrial boiler, the industrial kiln, the
ship power plant and etc, and effectively improve the utilization
rate of the fuel, and the heat exchange element is arranged at the
tail of the system flue.
Description of H-fin boiler tubes
The heat transfer tube of the boiler adopts the H-shaped fin tubes,
it is to weld two pieces of steel with arcs in the middle of the
arc symmetrically onto the raw tube to form the fins (ribs), the
front shape is quite like the letter "H", so it is called H-finned
tube. The fins of the H-finned tube are rectangular, approximately
square, with a length of about 2 times the diameter of the tube and
an extended heating surface. H-finned tube can also be made into
"double H" finned tube of double-tube, with good rigidity
structure, it can be applied to the longer row of the tubes.
Advantages of H-finned 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
(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.
(4) Fins and steel pipe welding fusion rate is high
Since the H fins have a unique zigzag structure (patented), the
weld fusion rate for fins and steel pipes can be as high as 98% or
more, to ensure a good heat transfer coefficient for H-finned
(5) Compact structure, high heat efficiency
The heating area per unit length is large, which of the H finned
tube is 7.8 times of the smooth tube, The butt welds are all welded
by argon arc welding, its welding quality is improved much higher
than that of the manual welding. With the size and the weight of
the equipment greatly reduced, therefore, in the same heat transfer
surface, the equipment investment is greatly reduced, and larger
space can be provided to the users on the aspect of the equipment
(6) Shock-proof and noise reduced
Due to the device structural design and the structural
characteristics of the H finned tube, it has the structural
characteristics of the muffler, so the equipment can function as a
(7) Convenient for installation, operation and maintenance
While installation, it only need to connect the equipment to the
exhaust gas outlet of HFO engine units, the equipment can be put
into normal operation; exhaust gas boiler has check door, which can
be determined the cleaning cycle according to the actual situation
to ensure the heat transfer effect and increase the working life.
