Pulverized coal (also known as powdered coal or PF – Pulverized Fuel) is typically used in power generating stations or cement kilns to optimize the burning process.
Pulverized coal is usually pneumatically conveyed into a bin and further to a weighing and distributing system, to be finally injected in the blast furnace.
The fine coal powder has the advantage that it is sufficiently surrounded by air to burn easily and release the heat. In this way, the combustion process is made efficient.
However, some foreign particles like plastic, greater coal lumps, and other solids, may enter the process if not intercepted beforehand and stop the pneumatic conveying of pulverized coal.
