Our process has an issue with moisture formation during process cycling that causes moisture injection into the silicon carbide brick of an upper quench tower. OEM seems pretty okay with our awful rebuild frequencies since they get paid for it but I was wondering about the use of coatings before bedding the bricks as an environmental barrier coating.
Has this been done before or are there any applicable standards/studies on it? I’ve seen EBCs more commonly used/studied for SiC turbine components but can’t for the life of me find any literature on quench towers, especially for this service (hot sulfurous gases in a co-current quench).
Also if Cerablak rings a bell for anyone that was one of the companies I’ve been communicating with. Praxair and Ultramet also have some systems but once again they seem specific to turbine units.
