Best Wood To Burn - Yukon Eagle Oil Furnace Owner's Manual

BEST WOOD TO BURN

All solid fuel, whether it is coal, pine, oak or any grain
has about 12,000 BTU's per pound if its moisture
content is zero. Wood that has been cut, split and air
dried for 2 years has about 8,000 usable BTU's per
pound. Hardwood such as oak or hard maple has
nearly twice the BTU's per cord as pine or aspen
because it is nearly twice as heavy.
Freshly cut wood has about 50% moisture content.
Wood that has been cut and split for 2 years has about
20%. Wood must reach at least 435º to ignite. High
moisture content wood does not allow the gases in
wood to get hot enough to provide complete
combustion, thereby creating smoke and creosote,
which is usable energy, but wasted because of
incomplete combustion.
Yukon-Eagle furnaces are designed to wring the most
energy possible from each log. Your furnace is
designed to allow the primary air under the grate to
create the initial burning. As the wood burns, gases,
which contain 40% of the energy in the wood, escape
to the top of the flame. The patented secondary air
system (the round tubes between the firebrick) draws
room air into the tubes and provides oxygen to the
firebox to burn these gases. The result is you will use
up to 75% less wood than stoves, furnaces or outdoor
boilers without these features.
