Really think so? As much as green wood smokes when first put on a bed of hot coals it seems to me that the smoke alone would choke out the chimney fire depriving it of oxygen
That theory makes about much sense as deciding you could stop a train by just putting your shoulder into it.
It.isn't.going.to.work.
Read the other posts about "freight train" and "sucking the air out of the house."
Even if it's not that severe, it just isn't going to work.
Just went surfing youtube --
Here's a nice pic of the "brown" smoke I mentioned before, and that's a pretty low-intensity chimney fire (I can tell from how the smoke is coming out). It's burning a heck of a lot more fuel and creating it's owned forced draft as the fire heats the air and it flows up the chimney. Any smoke from a green log doesn't amount to a pimple on an elephant's butt:

Decent, but I've seen better:

Oh, here we go...this is about an 8-3/4 out of 10...guy who posted it mentioned he had been having a trouble getting a draft started for a while!:

(Just from what I can see in the videos, the middle one would be the biggest pain for my fire company because it's burning right around that metal cap, it's not like you can just toss the chimney bombs down the flue. It's probably the creosote right on the cap itself burning, so it should go out soon enough...but if it's actually creosote further down burning and that's the flames venting then it's a pain. I'd probably try a dry chem on the roof to see if we could knock down the fire on the cap, or if Chimfex didn't help then maybe shoot it up the flue from down below.
Until we get the cap off, you can't use chains to clean it out or old car side-view mirrors to take a look down the flue to see how it looks. BTW, hold the mirror over too long and the chromed plastic will suddenly melt and the mirror falls down the flue
The other two look like cake jobs as long as the chimney is well built inside.)
