Boiler Pin tubes, Carbon Steel Boiler Pipes

Qingdao Kaineng Environmental Protection Technology Co.,Ltd (Stock Code: 838388) is located in Jiaozhou, Qingdao, the national leading high-tech Enterprise, and specialized in producing submerged arc furnace exhaust gas Boilers, power plant low temperature economizers, generators exhaust gas Boilers. It is formally listed on main board on August 5th,2016,  referred To as Kaineng Tech. the company mainly manufactures energy saving and Environmental protection products, such as flue gas exhaust gas boiler, low Temperature economizer, oil and gas fired exhaust gas boiler, pin fin tube, H-finned tube, marine boiler and different kinds of pressure vessels and so on.

Pin tube exhaust gas boiler adopts pin tube 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 tube 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 tube 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 tube 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 tube, with strong turbulence. Good self-cleaning performance
