| Abstract: | Experiments are carried out for two types unusual eddying tube fuel perheater,and the results show the total heat transfer coefficient is 1.2~1.262 times and friction factor is 2.8~9.0 percent higher than that of smooth tubes with the same size.Under the same heat transfer condition,C type preheater can save area by 20.1 percent and copper material by 19.5 percent ,it proves to save energy greatly. |
