Feed Coal - an overview | ScienceDirect Topics

Each pulverizer supplies coal to one level so that the firing is always balanced. In most of the tangential firing systems, the burners can tilt 30 degrees up or down, which causes the fireball to move up and down, thus aiding in controlling steam temperature and combustion conditions. These are called tangential tilting burners.

Vertical Grinding Mill (Coal Pulverizer) - saVRee

Coal Pulverizer Purpose. Irrespective of the machine used to pulverize the coal, all coal pulverizers have a similar purpose. Coal pulverizers are used to dry, grind and classify. Drying is achieved as hot gas passes through the pulverizer and removes moisture from the pulverized coal. The hot gases used should have a low oxygen content, this ...
