Boiler Performance and Mill Outlet Temperature - Bright ...

Nov 11, 2009  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. In fact in cases where moisture levels are very high the tempering air required will be zero.

Pulverizer - Wikipedia

The primary air input to a ball tube mill performs a dual function. It is used for drying and as the fuel transport medium, and by regulating it the mill output is regulated. Governed by the pulverized fuel outlet temperature requirement, the cold air and hot air dampers are regulated to achieve the correct primary air temperature.

Lime kiln - Wikipedia

The fuel is injected part-way up the shaft, producing maximum temperature at this point. The fresh feed fed in at the top is first dried then heated to 800 °C, where de-carbonation begins, and proceeds progressively faster as the temperature rises. Below the burner, the hot lime transfers heat to, and is cooled by, the combustion air.
