(Sigh)
I spent 25 years of my career burning shit for a living. When I went home, I burned wood to stay warm 7 months out of the year.
In the twilight of my career, I taught other operators from accross the state, how to properly and efficiently burn shit.
If you know what you are doing, and understand thermal conversion, you can burn almost anything in a wood heater.
I could write a novella in this thread about how wrong some of you are. All it would accomplish is arguments and French models telling me how much fucking firewood they've cut and or burned.
Most people are clueless about what is actually happening in their wood heater.
People like to talk about BTU rating of wood. At the same time they tell you to stay away from yellow pine, or pine in general. Heart pine or high sap pine will burn like #2 fuel oil.
I could design a system that would burn anything you put in it, including dried horse shit. Unfortunately, the EPA doesn't want people burning wood.
If you have a catalytic system on your freeboard, you have to operate it properly.
You cannot burn low fires in them, you can't burn green wood, you can't burn much pine.
A proper wood burning reactor needs to be much larger than most folks would want to put in their house.
Creosote should be burned off in the freeboard. Problem is.....that ends up being your flue.
If its dry, burn it. The drier the better.
You don't "ignite" anything, until it is bone dry. Unless you live in Death Valley, your wood pile aint dry.
Combustion dont be like you think it be....
