    These were on Craigslist, they show to go on the damper or they are a dampener catalytic converter. I wouldn't know how well they work or even if they do. I would think that the stoves who make their own are likely to be designed for that but this must turn any stove into a "cat stove" for the shorter benefit. Not that I want to do this but if I could think about a better efficiency without breaking the bank, this might be it.

    That probably would have worked okay in my old smoke dragon.
    I wouldn't put one in my current stove and set up though

    Im just wondering if anything like this was even effective. FWIW its a nice idea but a quick fix isn't a smart one.

    Seriously. I like that quote. I wouldn't be surprised to the guys who decide to mess with their set up and have something happen to it. Again wouldn't do this to my stove, I just needed the education to know this isn't a good idea.

    Looks like the source of combustion would occur in the flue pipe itself. With that being said, I would be wary about increasing the temps in the flue pipe (assumption?) and the need for greater CTG....?

    Just buy the EPA stove and be done with it.

    If i have a ceramic fiberboard baffle then thats just a barrier for unburned hydrocarbons to ignite. Im keen to see these secondaries but I was thinking that a dampener of this kind would only slow down the travel of gases that produce such in the firebox. Secondaries are...new to me. To say the least.

    I am curious if this would be better suited for the expa exempt stoves that have the damper right in the flue instead of it being in the pipe.

    Yeah this should be a controlled measure. Not a fueler.

    Interesting, might try something like that on our smoke dragon but we have a chimney liner instead of pipe now.

    Think about function. The point to a cat is to raise temperature in the home and burn unburned carbon where there is enough oxygen present already to do that. What is the benefit of raising the temperature in an already hot stove pipe, hot enough to light off a cat? It might work some to prevent a creosote build up, but if you run the flue hot enough to light off a cat combustor I am guessing you already don't have much creosote.

    Note: I am just thinking it through. I have never tried one and would be a hard sell for a vendor of those things.

    Class a is rated to 2100, what is single wall rated to? I'd be worried it would melt dbl or single wall interior pipe. Might leave you with a glob of molten metal somewhere you don't really want it
