explosion limit
Thread Content
Are the data we require when performing replacement related to the explosion limit? Where are the explosion limit values applied?
It is related; by shifting it outside the explosion limit, accidental accidents can be prevented
The purging of the furnace and fuel gas system is definitely related to the explosion limit.
This is related to the purpose of your replacement: 1. For example, if you need to carry out welding work after the replacement, then you must take into account the explosion limit； 2. If slotting operations are required after the replacement, the maximum allowable concentration of harmful gases must be taken into consideration ； (If there are sufficient protective measures, this can be ignored as well.) 3. If the equipment is only stored after replacement, this can be disregarded ；
It is related; shift it outside the explosion limit. This way it will be safe.
It is related. For details, please refer to HG 20660-2000 \"Classification of Toxicity Hazards and Explosion Risks of Chemical Media in Pressure Vessels\"
The purging of the furnace and fuel gas system is definitely related to the explosion limit.
If welding or hot work is required after the replacement and it involves work in a confined space, please refer to the \"Safety Specifications for Special Operations in Chemical Production Units\" GB30871-2014
The settings for fire testing samples and combustible gas alarms are both based on the explosion limit.
If your assignment involves flammable and explosive gases, it is necessary to take care to avoid situations where these gases are within their explosive range; encountering an ignition source in such a range can lead to fires or explosions. Ignition sources are very difficult to eliminate, and it is also important to note that temperature has a significant impact on the explosive range of flammable gases – the higher the temperature, the wider this explosive range becomes
