Dear Elisha, This might work. Suggest replacing dirt with #20 mesh sand. Easy to get (used in mortar) and easy to separate from ash fines and larger material due to being all the same size and no organic fraction.

In the lab you can have 1 metal bucket 1/2 full of dirt and 1 empty bucket/pot or another one half full of dirt and a sieve. You throw the fuel in one bucket, smother it with dirt from other and then use the sieve (screen) to remove the dirt from the fuel, having the dirt fall into the empty bucket...you may need some plastic sheeting or something to catch the dir and asht that falls outside but it should give you a better quality fuel then water soaked fuel.

Water puts out a fire by taking away its heat. So wondering if there is another method that could be used? Combination nitrogen gas and pieces of steel in a tumbler? Must be some way besides water.

The assumed energy for the wood and char is a major source of imprecision in the test. As for quenching with water: unfortunately we need to know the residual moisture content of the fuel 'as removed'. That varies a lot depending on the stove type. Quenching it with nitrogen is an alternative.
