Abstract

Abstract:

In calculating the external fire discharge capacity of pressure vessel safety valves, the calculation of the wetting area of horizontal vessels with elliptical heads still lacks a simple and accurate calculation formula. Since the petrochemical industry mostly uses 2:1 elliptical head, in order to calculate its wetting area more accurately, it is necessary to find a method that can easily calculate the surface area of 2:1 ellipsoidal crown. In this paper, the results obtained by mathematical methods and data fitting combined with the program approximation calculation method are verified, and a more suitable calculation formula is obtained to optimize the design of safety valves of horizontal vessels with elliptical heads under fire conditions.
