The applications for kind of air pre-heaters used in current refinery and chemical units in China are generally introduced.By descriptions of the features,fabrications and acceptance re-quirements of new cast plate-fin air pre-heater,it is clear that the new cast plate-fin air pre-heater has lots of advantages,such as,it can effectively resist the dew point corrosion at low tempera-ture,it can absorb the low-grade heat energy and can ensure the longer life of air pre-heater at the same time.If it is used with the tube-bundle type or plate type pre-heater together,the invest-ment cost can be decreased and higher heat efficiency of fired heater can be achieved in order to re-alize the energy conservation and emission reduction.
