Stainless steel mesh in flue?

[Easy Livin’ 3000]

Some utube guy who builds his own stoves mentioned that he puts stainless mesh in his flue. Says it glows and burns off gasses that make it past the baffle. Sounds reasonable to me. What am I missing?

I have similar in the 8" Pipe outside to prevent birds getting into the Pellet Stove. Stupid things. One got in last year. But having it there it might clog up and prevent good airflow. Easy to clean?

There were some early secondary comdustion systems that worked similarly. But you need fresh air directed at that mesh.

Dick Hills last masonry stove used a stainless steel grid for secondary combustion.

Wonder if there would be enough air rolling up from the secondary tubes?

There should not be. My old cawley lemay had a cast iron grid that had fresh air dumped on it that really did burn pretty clean.

Another "pipe dream" bites the dust.

Except this one actually involved a pipe, er, chimney pipe.

Not to mention mesh that fine even if it was burning stuff would be clogged with flyash in a couple days.

I wondered about that.

I have so much high priority stuff to do already, I shouldn't even be thinking about stuff like this. But it is nice to contemplate.

In the flue? I agree with the flyash buildup and reduced draft concerns (and how would you get it in and out of the flue for cleaning)? Not that it's not possible just because I don't know, but still... must be relatively low to soak up enough heat to glow enough to ignite some forgotten volatiles?

Woodstock used Iconel screens inside the firebox of early Progress Stoves to catch flyash before it clogged the Cat. It was supposed to burn up the flyash (kind of like a pre-cat) but it ended up clogging. The Iconel is super temperature resistant but after a season's use it turned brittle and crumbled. They no longer install that screen in new stoves.
