The
physics in the fuel
The first thing to consider is the fuel we use to run a
wood stove, i.e. wood. There are two different general
categories of wood, hardwood and softwood, and then
there are many different species of wood that fall under
these categories. For these purposes though we will
simply talk about the general properties of wood. First
we will look at what wood is made of, then where wood
gets its energy, and finally how wood transfers that
energy.
