Abstract:

One of the main reasons why the pollution discharged from stack of coke oven battery exceeds the limits regulated by environmental protection standard is the leakage of raw gas from oven chamber to heating wall with going through micro cracks of the chamber wall.Therefore to keep tightness of the oven walls during long period of operation is the important condition for the oven battery to reach the environmental protection level required by the standard.The RPR-SL technology is a kind of “precise maintenance and repairing” technology of the oven chamber which can effectively diminish the micro cracks of the walls causing the leakage of the raw gas.It is also regarded as the technology eliminating pollution sources to reduce the pollution discharged from the stack of the coke oven battery.
