I've been thinking of how to better control the burn in my DS Machine after re-loading with coal, especially at higher temperature settings. The issue I've been having is that the stove would cool a bit after reloading, and the tstat would open too far. The fire would get too hot, too quickly, and then the tstat would completely close and the chain would be dangling loose since the stove temp overshot well past the tstat setting.
When the stove is at a low burn, I have no problems. The problem occurs when I want more heat, and using bituminous only excaberates it. I decided to try a makeshift fix to start : (edit - The edge of the coal hod is keeping the flap from opening more than about 1/4")
So far, this has worked beautifully. I was even able to toss on a pile of high vol coal from Valier's. No more raging infernos!
I am thinking a permanent solution might be to build a manual damper that fits behind the air inlet flap, so the max burn rate could be set there.
I'm curious to hear others thoughts on this arrangement.
