Abstract:
1. A method for cleaning a coke-oven door having seal edges and membranes attached to a coke-oven door plate, the method comprising the step of: pressurizing a cleaning tool having a nozzle that projects a compressed-air jet; opening the coke-oven door while the seal edges and membranes are at a temperature of 130° C. to 200° C.; and immediately thereafter cleaning the coke-oven door by displacing the nozzle back and forth between and along the seal edges and the coke-oven door plate while directing the jet of the compressed air at the membranes and seal edges such that tar is removed from inside surfaces of the membranes and the seal edges; and orienting the nozzle such that the compressed-air jet strikes the surface to be cleaned at an acute angle of less than 45°.
