Finned casting for heat recuperator

　　








Heat recuperators burner castings
  Burner casting is the critical heat transfer element, long-term work in high temperature flue gas condition, such as the boiler heat exchange with burned casting, high temperature and high pressure and in a corrosive atmosphere, so it should have a high performance metrics.
1), Anti - corrosion
2)Anti - wear
3)the lower contact hold
4)Higher Stability
5)ability with preventing dust.
  In order to improve the thermal efficiency , we usually add the fin on the surface of heat exchange tube, the increasing of heat exchange tube surface area (or internal surface), so as to achieve the purpose of improving thermal efficiency, so the heat exchange tube called a finned tube.
