玻璃厂燃气系统爆炸危险环境分区计算

Calculation of Hazardous Area Classification for Gas System Explosion in the Glass Factory

根据目前国内规范,爆炸危险环境的划分除了一般性规定以外难以有具体标准,在具体划分时仍需要根据环境、生产经验、经济特性等多重因素具体分析。该文根据《爆炸危险环境电力装置设计规范》GB 50058和国际标准IEC60079-10-1的内容,提出一种划分方法,并结合玻璃厂的设计经验,以玻璃厂内天然气配气室为例,进行爆炸危险环境分区的划分。

According to current domestic regulations,the classification of explosion hazardous environments is difficult to have specific standards beyond general provisions.In specific classification,it still requires detailed analysis based on multiple factors such as environment,production experience,and economic characteristics.This article proposes a classification method based on the"Code for Design of Electric Power Installations in Explosive and Hazardous Environment"GB 50058 and the international standard IEC60079-10-1,and combines design experience from glass factories.Taking the natural gas distribution room in a glass factory as an example,the classification of explosion hazardous environments is carried out.
