ESTIMATION METHOD OF COMBUSTION RATES OF PULVERIZED COAL FOR BLAST FURNACE INJECTING

摘要

PURPOSE: A method for estimating combustibility of pulverized coal in a furnace is provided to stably increase the output of blast furnace by estimating the combustibility of pulverized coal. CONSTITUTION: A method for estimating combustibility of pulverized coal in a furnace comprises following steps. The content of non-burning materials included in pulverized coal is calculated (100). A coke sample in the furnace is collected through a blast inlet for blast furnace (200). A powdered coal sample is separated from the collected coke same (600). The content of the non-burning materials included in the powdered coal sample is calculated (400). The combustibility of the powdered coal sample using the content of the non-burning materials (500). [Reference numerals] (100) Measuring a first non-burning material; (200) Collecting a coke sample; (300) Step of separating a powdered coal sample; (400) Step of measuring a second non-burning material; (500) Step of calculating combustibility; (600) Step of separating a sample
