A Innovative Solution to the Problem of Mill Rejects in

2008-10-7  The amount of mill reject is significant in older operating plant. In India for example, it is about 0.5–1.0% of coal throughput into the boiler. In this paper, an exercise is undertaken to show how these rejects could be burnt to produce low pressure process steam, which could save the bleeding of main steam of the power plant and thereby augment power generation.

Leaching of trace elements from Pittsburgh coal mill

2017-2-15  Mill or pulverizer rejects are the dense, difficult-to-grind fraction of feed coal rejected and removed by a coal mill or pulverizer to decrease coal's sulfur content and increase its heating value before combustion (EPRI, 1999, U.S. EPA (Environmental Protection Agency), 1988). Milling or pulverizing coal preferentially removes non-combustible and undesirable material, such as pyrite and other sulfide minerals, before combustion, and this enriches the resulting rejects

Analysis on Abnormal Rejects Discharge of a Medium

A series of abnormal phenomena emerging in normal operation conditions of the medium speed pulverizers in a 600 MW unit are introduced. The effects of the primary air (PA) mass flow and nozzle ring passage area on the pulverizer rejects (PRs) discharge are analyzed. The results indicate that the root cause of all these abnormal phenomena is the lower nozzle PA velocity led by the narrowed
