Ignition Temperature of Coal. 5. Practical Applications

Abstract

If the ignition temperature t_ig of the unoxidized coal determined in accordance with Ukrainian State Standard DSTU 7611:2014 is used to check the rank assignment of coal concentrates supplied to the coke plant, inconsistency of the actual and declared ranks of the coal may be identified in timely fashion, the properties of the coal may be preliminarily studied, and the results may be used in adopting measures to maintain the specified rank composition and properties of the coal batch and also to stabilize the quality of the blast-furnace coke produced. Using the ignition temperature to monitor the rank composition and quality of the coal concentrates supplied to the plant offers economic benefits, by the prevention of losses due to changes in coking-batch quality, which affect the yield and quality of the coke produced.
