2018-2-1 Proper design and operation of the pulverized coal burners protects the pulverizing system from ignition from the furnace fire. The coal/ air mixture enters the furnace through a burner nozzle at velocities in excess of the flame speed. Thus, the flame front is held stable at a distance away from the end of the nozzle where

2018-10-2 height is about 1.5m. A small fire took place, and it was detected and extinguished in time. Thus, a regulation is issued that height of coal pile should not exceed 1 m, and when the temperature inside coal is more than 50°C, the raw coal piles should be turned over. After that, no accident in raw coal storage has occurred.

2021-4-3 Coal Bunkers. A deep-seated hot spot in bulk storage can be very difficult to extinguish. Earlier detection is key when combating a silo/bunker fire. Fixed CO monitoring equipment has been proven to be the most effective tool in detecting the early signs of combustion. The principle of this protection is to push CO2 vapour through the coal ...

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.
