Introduction. Explosion de-coupling is a technique in the field of constructional explosion protection, aiming to mitigate the impact and damage caused by the effects of explosive events on interconnected equipment, especially the self-reinforcing effects of accelerating flames and pressure transferring through ducts.

Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW.. B&W's pulverizers, found at power stations throughout the world.
There is no need to stop for maintenance during the operation period of coal mill. The replacement of spiral blade and cylinder liner can be carried out along with boiler maintenance, so the maintenance cost of coal mill is greatly reduced. 1.8.4. The air coal ratio is low. The low air coal ratio is determined by the structure of the coal mill ...
Due to its fine particles and volatile nature, coal dust poses a significant explosion hazard. Mechanism of Coal Dust Explosions. A coal dust explosion occurs when fine coal particles become airborne and come into contact with an ignition source in an enclosed or confined space. The explosion hazard is magnified by the following factors:
