Differential crushing, oiling, stamping, partial briquetting and preheating have all been advanced as ways of improving oven throughput, preference being given to preheating as the most effective method, combined with coal crushing in an air-entrained mill system: this gives a much stronger charge. Oven throughput is raised, or alternatively the lining life extended by decreasing its thermal loading. Preheating should also counteract the stressing difficulties encountered in rapid coking, though research favours moderate coking speeds of 37-40 mm/h in wide ovens (450 mm minimum). Reducing Dinas wall thickness by 10 mm reduces the coking time by 1 hour. Pushing figures should reach 120-130 ovens per day with fully automatic charging and high-rated machines. There is a case for oven widths up to 600 mm to raise the coke output, and at the same time moderate the daily pushing requirement.
