ABSTRACT:
Gases formed on charging a coke oven are extracted, burned and washed. A gas-handling system, mounted on a machinery truck of the coke-oven plant, is used. An extractor unit of the system comprises an extractor conduit which is connected to an updraft pipe of a coke oven during charging of the oven. The gas-handling system specifically comprises a combustion chamber shaped and dimensioned to ensure a gas flow at a velocity which does not exceed 10 meters per second. The combustion chamber comprises a heat-retentative lining to ensure that the temperature within the chamber does not fall substantially below the ignition temperature of charge gases between successive charging operations.
