I am not sure if the 'blankets' being referred to are catylytic material. I have a catylytic stove but my catylytic material is like a honeycomb that the smoke goes through. If I don't keep it hot enough it will clog up with soot and creosote. What I find is that you have to get the stove hot to get the catalytic material going. Once you get it going you can dampen the stove and or feed it less wood/pellets. The material seems to combust all the smoke. It is great as it is smokeless and the chimney stays clean. I had a Citation made by Falls River Iron Works. I'm not sure they are still in business. I've had it for 20 years.
