Since I ordered a replacement cat for my Keystone, I've been doing a ton of reading trying to figure out what I did wrong - if anything and making an effort to better understand the cat combustor and it's operation in general.

Below are some links to some interesting articles/websites with cat info on them.

http://www.chimneysweepnews.com/Combustors.htm

http://www.sud-chemie.com/scmcms/web/page_en_7529.htm

(note Sud-Chemie's EnviCAT LongLife Plus Metal brazed stainless steel cat. This is the one Woodstock sent to me to replace my old cat. It is not suceptible to degradation by potassium as was discussed on another post of mine. Also more durable against thermal shock)

http://www.woodstovecombustors.com/ (this is Condar and they have a steel cat now too)

http://firecatcombustors.com/ (this is Applied Ceramics. My Keystone lists them as the maker of the cat I had when I bought the stove. They have some intersting videos too)

Enjoy the reading!

Haven't read this all yet, but it looks like it might have some good info:

I thought there was another link posted here at one time that had a guy from a combustor company talking about them.Maybe I can find it...

Sud Chemie makes the S/S cats for Condar.. This information was given to me by the Sud Chemie rep when I called them for information..

Good info, I was wondering if those new steel cats would help with the potassium problem. Didn't think they would be a little less efficient though since they have more surface area than the ceramics.
 
not having good results with my steel cat from woodstock..ordered a new ceramic from applied ceramics..i talked to the guy there, he says,he has been there 30 yrs,he has seen the steel cats come and go they never catch on...they contain less precious metals than the ceramics..

I don't see how they could contain less precious metals when there is more surface area? I guess we shall see over time how these steel cats work out, so far I like mine just fine.

Ceramics may absorb some of the coating unlike S/S so that could be why .. I like the S/S cat so far here too and no worries about thermal shock..
