Types of pulverised coal firing system - BrainKart
Pulverised coal firing is done by two systems: i) Unit system or Direct System. ii) Bin or Central system . Unit System: In this system, the raw coal from the coal bunker drops on to the feeder. Hot air is passed through coal in the factor to dry the coal. The coal is then transferred to the pulverising mill where it is pulverised.

Association in their Codes 85E - 1974, "Prevention of Furnace Explosions in Pulverized Coal-Fired Multiple Burner Boiler-Furnaces" have provided good system design and operating guidelines. These documents should be studied and understood by all
Advanced Development of Pulverized Coal Firing Technologies
Pulverized coal fired boilers use coal of several tens of micrometers in size and then fire such pulverized coal in a suspended state inside the boiler furnace. Roller mills are commonly used as pulverizers due to their low power consumption. They pulverize coal between a roller and a rotating pulverizing table. To meet society’s needs for
OPTIMIZATION OF COMBUSTION IN PULVERIZED COAL FIRED BOILER
Also boiler efficiency increased and NOx emissions reduced at optimized operating conditions. Ren Jianxing et.al. [4] studied a 300 MW Coal fired unit using three kinds of mixed coal A, B and C. Under the rated load conditions characteristics of coal and burning characteristics were studied. The objective was to optimize combustion and enhance,
