Dust explosion venting regulations1 ScopeThis document specifies the technical requirements for dust explosion pressure relief, the installation, use and maintenance requirements of explosion pressure relief devices, and describes the corresponding verification method. This document applies to explosion pressure relief of process equipment and facilities in dust explosion hazardous areas. This document is not applicable to places with coal mines, fireworks, explosives, strong oxidizers, and toxic or corrosive dust.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document. For referenced documents without a date, only the version corresponding to that date applies to this document; for referenced documents without a date, the latest version (including all amendments) applies to This document. GB 15577 Safety regulations for dust explosion prevention GB/T 15604 Dust explosion-proof terminology3 Terms and definitionsThe terms and definitions defined in GB/T 15604 and the following apply to this document. 3.1 Process equipment (including vessels and piping) in which combustible dust-air mixtures exist. 3.2 Explosion venting Explosion venting Pressure relief By opening the pre-designed pressure relief port, the unburned mixture and combustion products are released to prevent the pressure from rising beyond the design strength to protect the container method. 3.3 pred The pressure peak of an explosion in the protected process equipment after explosion control measures have been taken. Note. If the explosion control measure is explosion pressure relief, the controlled explosion pressure is also called explosion relief pressure. 3.4 pred,max The maximum value of the controlled explosion pressure (3.3) obtained by systematically varying the concentration of combustible dust. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB 15605-2024_English be delivered?Answer: Upon your order, we will start to translate GB 15605-2024_English as soon as possible, and keep you informed of the progress.
