Development of Mill-burner System for Low-rank Coal with ...

As drying for high-moisture coal requires more heat at a mill, the high-temperature gas at the mill inlet must be applied. Supposing that the moisture content in pulverized coal at the mill outlet is 30%, the gas temperature required at the mill inlet is considered to be approximately 450°C.

Pulverizer Application for High Volatile High Moisture Coals

DESIGNING FOR HIGH VOLATILE COALS: In the contract engineering phase, the pulverizer system is designed for sufficient temperature and primary air flow, through the crusher dryers, to obtain necessary coal moisture reductions while simultaneously producing the lowest practicable pulverizer inlet temperatures. Since regenerative type air heaters are practically limited to 650-700 OF, the flexibility in

Coal Drying Improves Performance and Reduces Emissions

causes less feeder hopper bridging and plugging problems. Coal feeders provide coal to the coal pulverizers (mills) where the coal is pulverized and dried. Dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness. Additionally, with less fuel moisture, more complete drying of coal can be achieved in the mill. This results in increased mill exit

Mill Inerting Systems Presentation to the ASBCUG

Higher moisture content requires temperature extremes inside the mill. High moisture, high volatile matter and highly reactive coals are prone to self heating and can spontaneously ignite due to rewetting. Rehydration is exothermic and dried coal that is stagnate anywhere in the coal mill can begin to smolder and burn.
