Port and Peep Hole Covers
Exhaust port covers are used in an anode bake furnace to seal off each individual pit sections exhaust flexi leg. Porthole covers reduce or eliminate ambient air from being drawn into the anode bake furnace during the fire. They also provide insulation and can be designed to compress slightly to make up for inconsistencies in the sealing surface.
Peep hole covers are very similar to port hole covers, except they may be smaller in size. Peep hole openings are most commonly used to insert sensors (thermocouples, TPR, ZPR) or burners into flue walls or for visual inspection of the furnace. Some furnace designs require separate peephole covers while others incorporate a peephole opening into a port cover.
