The Combustion Process
Combustion in the Harman® Oakwood is precisely controlled
and is best explained in two parts.
During a wood re, combustion air enters at the bottom front
of the stove where it travels upward through channels at either
side of the front door. From the manifold located above the
front door, it is directed into the rebox as a sheet of air owing
between the glass and the wood. This concept helps to keep
the glass clean, while providing the oxygen needed to sustain
burning. This is what is known as "Primary Combustion".
Additional air enters at the bottom rear of the stove body.
Some of this air enters through holes in the rear bricks
where it is used to revitalize the re at the rear of the rebox.
The remainder is delivered into the "Firedome" combustion
package where the "Secondary Combustion", or re-burning
of the smoke, occurs.
During combustion, the burning of wood proceeds through
several stages. The initial or evaporation stage is where
the moisture in the wood is driven off in the form of steam.
A second stage is where the volatile gases contained in the
wood are released and burned. This represents most of the
wood's heating capacity. The nal stage is the charcoal stage
where the charcoal burns the remaining heat content in the
wood fuel. Ash remains after the burning is complete. Within
the primary rebox two or more of these stages of combustion
are occurring at once.
Two important controls - the damper bypass handle and the
air control lever regulate the operation and output of the stove.
To open the top or front loading door, you must open the
damper bypass, or smoke will come in the room. In this
mode of operation the combustion gases go directly from
the main combustion chamber to the ue collar and exit into
the chimney.
NOTE: The bypass damper must be open for smokeless
loading. Open the bypass damper by turning the handle
clockwise while facing handle.
