DMT's specially developed door cleaning system, for coke oven door seals is both contactless and fully automatic, hence reducing the amount of mechanical abrasion compared to common brush/scraper-systems. Compressed air is used, guided by a robotic arm, to clean the coke oven door sealing system. As this robotic arm is installed on the coke pusher machine or transfer car, the coke oven door sealing system can be cleaned on-site during the pushing procedure without the necessity to remove the door from the battery.
This cleaning system is not depending on a specific type of sealing system and ensures:
- Effective cleaning, avoiding damages of the door sealing
- No additional wastewater
- Cleaning time max 150 s
- Compliance with environmental requirements and safety regulations
This is achieved by a low distance between nozzle and door sealing over the whole traverse path and a rotatable nozzle.
