about coal mill pf boiler

Coal is pulverized in the coalmill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle. The coal and primary air are then introduced to the coal nozzle. Swirled air, coupled with the burner throat’s flow-shaping contour, enables recirculation patterns that extend into the furnace.

    Boiler Performance and Mill Outlet Temperature Bright

    Pulverizing mills in boiler plantsplay a major role in preparing the coal for firing in a boiler. Coal, being a heterogeneous fuel, varies in its properties; the variation depends on many factors like type of origin of coal, formation, etc. Two major parameters which decide the mill capacity and performance are the hardness of the coal and the total moisture level in coal.

    How to Run a Coal Fired Boiler at the Best Efficiency

    There are a few minor losses in boiler which can also be optimized like the mill reject loss and the carbon monoxide loss. Pulverized coal fired boilers the total losses account toabout 12 to 14%. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions.
