Small cracksEmpty <strong>Oven</strong>Through-<strong>wall</strong> <strong>leakage</strong>• Wall crack between chamber and flue – caused byexp/cont & pushing the coke especially when sticking;• Raw gas leaks from chamber to flues during coalcharging and coking;• Interferes with combustion, lowers excess O 2 , leads toincomplete combustion, hence higher CO and soot(carbon particles);• A larger amount <strong>of</strong> combustibles such as methane(CH 4 ) from both leaked raw gas and fuel gas remain unburnt;• Hence, measurement <strong>of</strong> CO, O 2 , CH 4 and particulatematter may be used as indicators for <strong>through</strong>-<strong>wall</strong><strong>leakage</strong>;• Assess coke oven <strong>through</strong>-<strong>wall</strong> <strong>leakage</strong> by undertakingwaste gas analysis at individual <strong>wall</strong>s.COMA Conf, Scunthorpe, ECOCARB 4-5 April 2013 4
