Briquetting of Coal Batch by Stiff Extrusion

Abstract

The briquetting of coal batch by stiff extrusion for use in the coke industry is considered, in response to the ongoing deterioration and instability of the available coal resources. Research results confirm that this is an effective method of producing strong batch components for coking. The influence of the binder on the briquet properties—mechanical strength, thermal stability, and water resistance—is studied. The optimal fractional composition for briquetting is determined. A hybrid binder is found to ensure high thermal stability and water resistance of briquets consisting of coal and coke breeze.
