Investigation of particle size of waste coal and agitation conditions on combustible matter recovery from waste coal by vegetable oil agglomeration

Abstract

In this study, a vegetable oil agglomeration was performed for coal recovery form Chinese waste fine coal. The effects of the parameters including particle sizes, agitation time and agitation rate were investigated based on the combustible matter recovery, ash reduction and efficiency index. It was concluded that particle sizes of waste coal, agitation rate and agitation time will influence on the recovery efficiency of combustible matter from its original waste coal by colza oil agglomeration.
