| Abstract: | Presented in this paper are formulas for calculating flow resistance and heat exchange coefficient of screwtubes, which have proved to be accurate and reliable in a prooftest on an in-service boiler. It is pointed out that variations of flue gas temperature at the inlet of a screwtube have little influence on the heat exchange and total flow resistance of the boiler, and suggested to raise the inlet flue gas temperature as high as possible in the design of a boiler. |
