Why is it that some wood leaves a ton of ash, and others hardly any? I guess that I have never gave it much thought as to why, I just accepted the fact that some does and some doesn't.
I always figured the heavier wood left more ashes since they gave off more BTUs.
This article kinda summed it up for me. http://www.fao.org/docrep/t0512e/T0512e0o.htm#4.1.2 the wood gasifier goto the last paragraph where it starts with Ash content. Some biomass is higher , in the 0.9% - 0.14% by weight. few are lower.

I think ash wood might do that because lots of people think it is dry and ready to burn when it's not quite ready yet. Hard wood that is still a little green leaves behind the most chunks that look like small cinders. Cold fires that are starved for air generate more of them. These chunks can be tossed right back into the next fire and they will ignite and burn to a powder.I've found Ash to leave the most - Wonder if thats why they named it "Ash"?

...but looks like a big factor in ash is mineral content of different spiecies.
