i was at menards looking at stoves. they had tubes with holes on them on the ceiling of the stove. what do they do ?

A simple answer- those are the secondary combustion air inlets.

If the stove gets to hot they spray water!
Just joking..others beat me to the answer!

I converted mine to a halon system, however I am finding it difficult to recharge the system

I am saving this link for my husband to read. I understand it, but he does not and goes from raging fire down to almost putting it out. He need to understand the concept of slowly damping down

A little elaboration....these inject heated air into the gases to burn off more of the smoke/gases. This is what makes the stoves burn more efficiently.

Wonder what would happen if we ran nitrous oxide into those tubes?

Just joking again!

That's right. What makes EPA approved stoves so efficient over older ones is that they are designed to burn a lot of the combustion products that otherwise would go up the chimney. Smoke, some gasses, etc. One way to do that is to put those tubes with holes at the top. They are supplied with air and get so hot that they burn those products. That's called secondary burning. Secondary burning is quite visible and adds to the light show. My wife calls them the afterburners.

Another way to do it with a catalytic burner.

That's the short version. Much more to learn about stoves if you are interested and this is the place to do it. Welcome to the forum.

yeah, i have a lot to learn. and you folks are nice enough to help me.

were does the secondary air come from ?

There are separate inlets to do that job that are non adjustable.
Though some have found ways around that.

Now THAT would be a runaway stove!

They are for picking off unburnt gasses that the wood fire did not burn.
