Explosion protection for coal grinding plants What should
Explosions in coal mill systems are confined explosions which means that the pressure effects must be dealt with by protective techniques to prevent the pressure rise from exceeding the strength of the plant either by venting the expanded air into the atmosphere or by suppressing the combustion.
