涉氢建筑物及容器泄爆设计方法实施

Core Viewpoint - The release and implementation of the group standard "Design Method for Explosion Protection of Hydrogen-Related Buildings and Containers" aims to enhance safety measures in the hydrogen industry, transitioning from experience-based judgments to precise calculations for explosion risk assessment [1][2]. Group 1: Standard Implementation - The standard, developed by various institutions including China Chemical and several universities, outlines design requirements for hydrogen-related buildings and containers, including calculations for explosion overpressure and maintenance requirements for explosion protection devices [1]. - It is applicable to industries involved in hydrogen production, storage, transportation, and usage, addressing potential explosion risks from hydrogen-air mixtures [1]. Group 2: Technical Requirements - The standard addresses deficiencies in existing gas or dust explosion standards regarding the accuracy of hydrogen explosion overpressure predictions, proposing specific technical requirements for calculation models and parameter selection [2]. - It includes a fitting calculation formula for maximum explosion pressure generated by hydrogen-air mixtures in buildings or containers without pressure relief openings, validated by extensive experimental data [2]. Group 3: Industry Impact - The implementation of this standard is expected to provide a solid safety assurance framework for the development of the hydrogen energy industry, supporting the safe and large-scale development of clean energy strategies in China [2].
