FIREBOX AND OTHER COMPONENTS
Firebox
Principles of the Firebox
Wood is burned inside the rebox to generate heat. This heat is absorbed into the water
in the water jacket. The rebox and water jacket are one
welded component and can be replaced. When the water
is up to temperature and the combustion air blowers are
off, the rebox must be airtight.
Operation of the Firebox
Temperatures within the rebox can reach 2,000 degrees
Fahrenheit. Exhaust exits from the rebox into the ue.
During normal operation, there will be a slight buildup of
black creosote on the rebox walls. This buildup will
sometimes appear aky.
Maintenance / Result
Wood should not be thrown into the rebox in a rough manner. Creosote should never have
to be scraped off the rebox walls.
