2. The hot air is used for transportation of the recirculating coal within the mill and also for transporting the coal from the pulverizer to the furnace. As the coal is continuously reduced in size, the smaller/lighter particles are swept from the bowl by the hot air. Hot air (and cool tempering air) is provided by the primary air fans.
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.
