Specifications
Boiler Pin Pipes, Carbon Steel/Stainless Steel Pin Pipes
Pin pipe exhaust gas boiler adopts pin pipe to strengthen the extended Heating surface of the heat transfer components, the heating surface of both Sides of water pipe can be greatly increased, meanwhile the strong turbulence Formed by the flue gas flowing through the surface of pin pipe can improve the Heat transfer efficiency and reduce the soot accumulation, with advantages of compact structure, high Heat efficiency, less equipment investment, and also with shock-proof, noise Reduced, fouling prevented, safe and reliable features
the flue gas flows through the surface of pin pipe to form a strong Turbulence, so that the heat transfer boundary layer becomes thinner to reduce the heat resistance and improve the heat transfer coefficient. Comparing to the Smooth tube, the average heat transfer coefficient can be increased 1.3-1.8 Times.
the experimental data shows that the convective heat transfer coefficient of the pin pipe is obviously higher 3 times than that of the H-finned tube and Spiral finned pipe. while gas speed is 10m/s, the convective heat transfer Coefficient can reach 165W·(m2·℃)-1.
(1)Pin fin is a cantilever structure, can vibrate with impact of airflow
(2)the strong turbulence is formed by the flue gas between the pin pipe, with strong turbulence.
Good self-cleaning performance
Pin pipe strengthens the expanded heating surface of heat transfer
Components, increases its heating surface of gas side, the heating exchange
Surface is 7-8 times larger than smooth tube 1.3-2.2 times larger than spiral
Finned pipe, so that the pin pipe exhaust gas boiler is with small structure,
Light weight, but its heat exchange surface is large enough.
