ESTIMATION METHOD OF ORGANIC SULFUR RATE IN COKE, ESTIMATION METHOD OF TOTAL SULFUR RATE IN COKE, BLENDING METHOD OF COAL USED FOR PRODUCING COKE, AND PRODUCTION METHOD OF COKE

摘要

PROBLEM TO BE SOLVED: To provide an estimation method for promptly estimating an organic sulfur rate in a coke, an estimation method for promptly estimating a total sulfur rate in the coke, and a blending method of coal used for producing the coke.;SOLUTION: An organic sulfur rate in a coke produced by carbonizing coal is obtained using following expression (1) shown by an organic sulfur rate and a volatile component rate in the coal. Organic Scoke=Q×(organic Scoal)×(1-R/100)...(1), where organic Scoke: the organic sulfur rate in the coke produced by carbonizing the coal (a mass% when a coal mass is set to 100 mass%), Organic Scoal: the organic sulfur rate in the coal (a mass% when the coal mass is set to 100 mass%), R: the volatile component rate in the coal (a mass% when the coal mass is set to 100 mass%) and Q: a coefficient (Q=1.0).;COPYRIGHT: (C)2014,JPO&INPIT
