Determination of the explosion protection rating for industrial facilities
Thread Content
I recently came across a project related to the treatment of organic waste gases from chemical plants, whose main components are non-methane hydrocarbons； The treatment process is RTO ； The owner insists that the power cabinets, instrument cabinets, instruments, and cables all be made to the BT4 explosion-proof rating. Since the equipment will be placed outdoors in the future, and RTO devices cannot be made to meet explosion-proof standards (they can only provide explosion venting), I don’t think it’s necessary to make them all explosion-proof, as that would increase costs ； What do you all think? Have you encountered such a situation?
Viewing electrical drawings: Explosion hazard zone classification diagram
1. Check the explosion-proof area classification diagram for the electrical engineering field. 2. Check what the original explosion-proof type is. 3. Consider explosion-proof and non-explosion-proof layouts.
