Coking partially briquetted coal charge under industrial conditions
Findings reported in the article include the increase in bulk density as a function of the proportion of coal-tar pitch bound briquettes in the charge, together with a reduction in vertical shrinkage and an associated differential heating of the coke cake in the upper part of the oven. The partly briquetted charge showed roughly the same amount of wall clearance as a conventional charge and pushed satisfactorily. Charges with briquette constituents show greater abrasion resistance and stability during thermal stress in the oven. Further trials should be carried out with partly-briquetted charges to study swelling and shrinkage, and the effect of briquetted weakly-caking coals. (13 refs.)
