Impact of Biocoke Utilization on the Cupola Furnace Operation and its Effect of CO<sub>2</sub> Reduction

Achieving green casting is the goal of foundry industry. This not only in perspective CO2 reduction based on a near future to fossil resource depletion but also self-sufficient stable energy supply and avoidance global risks. Significantly, cupola operation, through history various efforts by each company, we have reduced coal coke ratio limit; other words, are controlling it with minimum origin consumption required for melting, so cannot reduce further reducing coke. In this article, engaged partially substituting biocoke that been developed recently. By expending （or substituting） fuel made from variety different substances, found characteristics operating cupolas difference maximum substitutional rate related substances biocoke. Moreover, practical technology utilizing Especially, verified operation can be operated without problems up conditional 20 mass% same calorific value.
