| Abstract: | The enhanced heat transfer technology for pipe and its application in caldron-shell oilfired and gas-fired boilers are introduced, and the heat transfer mechanism of enhanced heat transfer technology and the existing empirical calculation formula of enhanced heat transfer for pipe are analyzed. Recommended parameters for the structure of some enhanced heat transfer elements are given by analyzing the structural features, enhanced heat transfer effects and application conditions of different heat transfer elements, and synthetically considering the factors in heat transfer and flow resistance. |
