  • Boiler Performance and Mill Outlet Temperature

    Boiler Performance and Mill Outlet Temperature

    The mill outlet temperature has a major impact on the boiler performance levels. The mill outlet temperature directly impacts the dry gas loss in boiler which is a major loss. This depends on the moisture level in coal the higher the moisture level the quantity of hot air required in mill for the same mill load is higher.

    The temperature at mill outlet is a key parameter for open pulverizing systems with fan mills. Higher mill outlet temperatures evaporate more moisture from the coal in the pulverizing system and the recovery of water from mill-exhaust can be more convenient due to the increase in the water dew point of the mill-exhaust.
