Abstract
An access door for a boiler or furnace has a water-cooled jacket mounted on a door panel frame for use in high temperature regions of furnaces and boilers. The door is large enough to permit a stretcher to pass through unobstructed. The water-cooled jacket has a series of baffles which direct water in a serpentine path through the jacket. Plant water, as opposed to boiler quality water, may be used to cool the door. A viewing port may be provided in the door as well.
