Explosion-proof design for gas user workshops
Thread Content
Recently, I have encountered quite a number of issues related to the explosion-proof design in the workshops of gas users: 1. Does the installation of a gas pressure booster in the boiler room affect the fire and explosion prevention requirements for that area? (The boiler specifications state that the main workshop does not need to be explosion-proof as long as open flames are used.) In large processing workshops classified as Category 2 and 5, natural gas is used for maintenance purposes; the valve box for this maintenance gas should serve as a secondary release source. Many of the electrical equipment in these processing workshops do not meet the requirement of maintaining a distance of 15 meters. The workshop is very large; are there any written regulations or generally accepted explanations regarding whether a low supply of gas affects the fire and explosion prevention properties of the building? Let the experts give some advice, and let’s discuss it together
1. Installing a gas pressure booster in the boiler room will not affect the fire and explosion prevention requirements of that area, but it is necessary to ensure that the booster itself meets the explosion prevention standards. At the same time, it is necessary to check whether there are flammable materials or other high-risk factors around the press; if so, appropriate measures must be taken to prevent problems. 2. For large processing workshops of Class D and E where natural gas is used for maintenance purposes, the valve box for the maintenance gas supply should serve as a secondary release source. However, in cases where the workshop is very large and the amount of gas available is limited, it may be difficult to meet the requirement of a 15-meter clearance distance. In such cases, it is necessary to conduct a detailed assessment of the workshop and take appropriate preventive measures. For example, combustible gas leak alarm devices can be installed in the processing workshop, and proper ventilation in the workshop can be ensured. In addition, it is necessary to communicate with the local fire and explosion prevention safety authorities to obtain their advice and guidance, and to ensure that one’s design complies with relevant regulations and **standards. .
