Abstract

Abstract: External fire is a common accident condition in petrochemical plants and safety valves are usually installed to prevent overpressure of pressure vessels. Reasonable calculation of the discharge capacity of safety valves in fire scenario is an important prerequisite for protecting the safe operation of pressure vessels. This paper provides an overview of the calculation formula for the discharge capacity of safety valves in fire scenario, and discusses the selection and determination methods of key parameters in the formula, aiming to provide reference for engineering designers.

Key words: pressure vessel, safety valve, fire scenario, discharge capacity
