Paper Title:
Comparison of the Computing Method for the Radial Temperature Difference of a Supercharged Boiler Steam Drum Shell Based on the Approximate Solution and the Current Chinese Standard
  Abstract

The radial temperature difference calculation of a steam drum shell is an important step in the process of calcu-lating its heat stress, so the current Chinese Standard recommended a computing method which was derived from the further modification to the simplified solution for the radial temperature of a steam drum shell. In order to derive the feasibility for the application of the current Chinese Standard computing method to a supercharged boiler, the computing method for the temperature difference of a steam drum shell, which was based on the approximate solution for the radial temperature of a steam drum shell and highly approaches to its analytic solution, was exercised. By analysing the computed results of examples, the conclusions show as follows: The current Chinese Standard computing method for the radial temperature difference of a steam drum shell can’t meet the calculation requirements of all the running work conditions and their courses of a supercharged boiler, and as a universal computing method, it can’t serve as a computing method for the same problem of a supercharged boiler. Whereas the approximate solution can apply to calculating the same problem of a supercharged boiler and a peak shaving utility boiler. Thereby the basis is offered for the selection and usage of the computing method for the radial temperature difference of a supercharged boiler steam drum shell, the pioneering researches on its interrelated problems and prac-tical applications.
