DEKOMTE proposed an internally lined access hatch, suitable for retrofitting to the existing ‘cold case’ exhaust system. The solution involved a new section of liner plate with aperture fixing to integrate with the existing liner plates, ensuring the insulation will be well maintained and protected from turbulence.
The door and liner plate interface features a double sealing system to manage the temperature gradient to the outer frame. The outer frame brings the door away from the casing, protecting from any further heat exposure or adjacent insulation issues. The Davit arm support mechanism was chosen to avoid manual handling issues with the manoeuvring of the door during outages.
