A metal shroud that can be retro-fitted inside a chimney to double burn smoke particulates and make a cleaner world.

The walls of the insert could be double layered containing a redesigned BUNGCO Cobra. Better efficient direction of heat is always welcome.

Because chimneys vary in size and design, the insert has a craftsman made metal sealing skirt. Also the computer modelling of the fireplace can show, with local weather data (now with 1000 year events) if the current cowling will give optimum results.

So If you have to smoke, make sure you bend that fire.

To burn unburned stuff, you need to introduce extra oxygen/air. I don't see anything in this Idea to accommodate that necessity.

Obviously, I need some of those snakey tubes to run the other way, to supply fresh oxidiser to secondary burn. Some for heat and some for air.
