The heart of the sterilization process is the steam boiler system. To uphold the performance of the steam boiler, regular cleaning of fire tubes is necessary to remove deposits build-up thereby enhancing heat transfer and reducing fuel consumption as well as preventing metal surface from corrosion. The existing cleaning procedure involves considerable manual handling operations potentially leading to repetitive muscle strain injury and dust inhalation. In addition, the health condition of the fire tube could not be validated readily.
