Certain innovative coke-oven repair techniques are reviewed that represent an engineered approach to a successful rehabilitation of all types of coke-oven batteries. These techniques have been developed during the last 10 years and experience gained on a number of repair projects has shown that these techniques operate as a cohesive and comprehensive method of end flue and through-wall repairs to gain additional years of operating life to coke-oven batteries. Extended operations approaching 10 to 15 additional years of service at lower costs than a pad-up rebuild and, while meeting the environmental emission regulations, are attainable using the techniques of: Proper tie-in joint preparation; Improved bricking up methodology; Preheating refractory during bricking up; Installation of spring-loaded bracing system; and installation of flexible coke-oven doors. Repair methods that do not incorporate the above techniques are subject to premature failure of the refractory. The old methods of wall cool down and installing refractory as if the battery was brand new are outdated technology. A technology supplier, with new techniques, can coordinate the construction contractor and the battery heating to obtain a successful coke-oven and flue or through-wall repair.
