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.

Rolling (metalworking) - Wikipedia
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
Inlet Performance - NASA
5-5-2015 · Mil. Spec., M > 1 : pt2 / pt0 = ni * ( 1 - .075 * [M - 1] ^1.35) The Mil. Spec. loss is a good first estimate of inlet recovery. Actual inlet performance may be greater, but is usually less than Mil. Spec. The magnitude of the recovery loss depends on the specific design of the inlet and is normally determined by wind tunnel testing.
