What determines how "dirty" wood is, when burned - meaning how much smoke / particulates you would get from a very efficient burn (e.g., good gasification unit) of a dry cord of different types of wood?
Some wood is lighter, some heavier. I would expect there to be at least a loose correlation between weight and the amount of heat I could expect to get from it. So, for instance, if I had oak and filled the burn chamber, versus, say, basswood, I would expect to get more heat from the oak, as much because it is heavier / more dense than anything else.
I was kind of expecting smoke production to be basically match the density of the wood I was burning. So, assume well-dried wood, assume efficient gasification unit, get a certain amount of particulates generated for a certain amount of heat generated, even though one would fill the chamber more often with lighter wood.
But it doesn't work that way, eh? What is it about doug fir, for instance, that leads to the only "High" listing for smoke generated, in the chart here: http://www.thefireplacechannel.com/burningwood.html
