摘要
Abstract
The precise calculation of safety discharge capacity for gas cylinders is a basic work for performing overpressure discharge design.The authoritative standard CGAS-1.1 of Compressed Gas Association Inc.specifies calculation methods of several types operating conditions of gas cylinders.However,these methods have not been well understood by many domestic researchers.In this paper,the calculation methods of safety discharge capacity for cylinders specified in CGAS-1.1 were analyzed.Results indicate that although different calculation methods were set for pressure release valve and other venting device respectively,the calculation formula was same after these methods were transformed to calculate the safety discharge capacity of real gas.Safety discharge capacity was not influenced by venting device type.The calculation method of discharge area was simplified.The discharge area only relates to cylinder volume and discharge coefficient,and has nothing to do with gas type and gaseous properties.关键词
