Presumption manner of corks reactor gas yield rate and oxygen content O

摘要

PROBLEM TO BE SOLVED: To provide a method for estimating the amount of a gas yield in a coke oven at sufficiently high precision even in the case of a high mixing rate of a non- or slightly-coking coal, and also to provide a preparation process of a coke where the difference of a target value and an actual value of a gas yield can be made small.;SOLUTION: The method for estimating a coke oven gas yield is characterized by estimating a coke oven gas yield Y (Nm³/t coal) converted into 4,800 kcal/Nm³, as a function of VM and VM×O on the base of a volatile matter of coal VM (mass %, dry) and the amount of oxygen O in the coal (mass%, dry). Y is estimated by formula (1): Y=A×VM-B×VM×O+C , where A, B, and C are constants.;COPYRIGHT: (C)2006,JPO&NCIPI
