Re: trick, yes good one and well practiced when needed.
Lol I don't think we started the fire with kindling in past two months. Even coming back from Xmas vacation it started with a single btu or match.
Spruce charcoal is wonderful for starting up easily.

Just a bit of kindling set off in there will get the two walls radiating at each other quickly, especially if they are extra dry from being near the stove on its previous burn. A chunk on top should moderate the airflow to increase combustion temperatures until it starts to burn through. This saves me a lot of time from making and fussing over kindling. A propane torch or a bit of wax or pitch are other labor-savers.

>> Thank you for your good analysis of your wood stove. I know there is a better design and I'm not sure if my stove is better or not.
>> Here is the thing. I burn spruce. My supply comes in 5 to 8 inch round logs dried for ~3 years. Not sure mc but guess around 15%.-20 % I try to maintain a very hot temp so the entire logs gasify and burn over a 12 hr period. (Absolutely no fuel prep. splitting etc is mandatory lol ) It's very fickle in setting damper and air intake but for the most part I am successful. The refractory bricks helps a lot. So that is 2 burns over a 24 hr period. ( it's been averaging minus 20 c over the last two months here so not much choice)Ive run numerous test of my theory for max efficiency under which this stove operates and settled on this operation because when the stove is shut down anywhere at the height of its max temperature and burn cycle and allowed to cool to 20 c it can be relight with a single match.
>> The volatile gases including h2o could be better used for sure. They cool and condensate on the inside walls of the stove and flue before they frac. completely resulting in biochar. The problem being the gases should be reheated, frac.ed with a catalyst and burned where the heat would be a benefit to the logs for pyrolysis. Thus enhancing the entire burn + 20%. ( +++ considering the exponential advantage of said catalysis and resulting heat)
