大容积钢质无缝压力容器处于火灾环境时安全泄放量的计算方法的探讨

Discussion of Method for Calculating Safe Relief Volume for Large,Seamless and Steel Pressure Vessel in Fire Environment

大容积钢质无缝压力容器安全泄放装置的设置和安全泄放量的计算,按照国内标准应该采用GB 150—1998、JB 4732—1995和《压力容器安全技术监察规程》规定的方法和公式进行计算,但对于容器处于火灾环境时,安全泄放量的计算没有给出明确的方法,本文针对此问题进行了论述和探讨。

For large, seamless and steel pressure vessel, the set of safe relief valve and safe relief volume shall be in accordance with the methods and equations stipulated in GB 150-1998, JB 4732-95 and ＂Supervision Regulations on Safety Technology of Pressure Vessel＂. But, for the vessels locating fire environment, there is no any method for calculating the safe relief volume. In this article, this topic was discussed.
