Slaking | Article about slaking by The Free Dictionary

Indicated coal is projected to extend as an ½ mile wide belt that lies more than ¼ mile from the outcrop or points of observation or measurement. Inferred coal resources – Coal in unexplored extensions of the demonstrated resources for which estimates of the quality and size are based on geologic evidence and projection. Quantitative estimates are based largely on broad knowledge of the geologic character of the deposit and for which there are few, if any, samples or measurements.

coal slaking rate test - cleanroominstruments

The ash fusion test gives an indication of the softening and melting behavior of coal ash at high temperatures within the boiler. Ash fusion temperatures are determined by heating a prepared sample of molded coal in a high-temperature furnace to temperatures exceeding 1,000 oC in both reducing and oxidizing conditions.

The standard reactivity test as a measure of lime’s quality

content of the coal (in coal-fired kilns) can significantly affect PM emission rates. Of the various kiln types, fluidized beds have the highest levels of uncontrolled PM emissions because of the very small feed rate combined with the high air flow through these kilns. Fluidized bed kilns are well controlled for maximum product recovery.
