High pressure spray cleaner for doors, etc. - e.g. for use on coke oven batteries

摘要

An appts. for cleaning doors, door jambs etc. comprises a rectangular, continuous track in which run carriages carrying nozzle assemblies connected by flexible pipes to a high pressure water supply; the nozzle assemblies each include at least two nozzles directing water in different directions onto the surfaces to be cleaned. Pref; there are separate systems for the doors and jambs. The system is used to clean sealing surfaces of coke ovens, etc., and avoids the use of scrapers which subject the surfaces to a high wear rate, resulting in loss of efficiency, atmospheric pollution. etc.
