Firebox
Principles of the Firebox
Wood is burned inside the firebox to generate heat. This heat
is absorbed into the water in the water jacket. The firebox 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 firebox must be airtight.
Operation of the Firebox
Temperatures within the firebox can reach 2000 degrees
Fahrenheit. Exhaust exits from the firebox into the flue. During
normal operation, there will be a slight buildup
of black creosote on the firebox walls. This buildup will
sometimes appear flaky.
Maintenance / Result
Wood should not be thrown into the firebox in a rough manner. Creosote should never have to be scraped off
the firebox walls.
