the bottom of the hatch
must enter the hole in
the scraper plate.
Bypass damper
The boiler's bypass damper is used to prevent smoke
entering the boiler room when wood is added during a
firing phase.
When the bypass damper is open, the boiler functions
as a supercombustion boiler and has shorter flue gas
paths. This increases the flue gas temperature and
reduces the efficiency.
Don't forget to close the damper after adding wood.
Combustion control
All air is supplied to the boiler via the draught hatch
in the ash hatch. The combustion is controlled by the
draught that the fan creates and by the oxygen supply
via the primary and secondary air that is supplied via the
inner ash hatch.
To optimise combustion and efficiency, the flue gas
temperature should be approximately 300°F.
The secondary air, 46, is adjusted so that the flame is
light yellow.
The soot reflects the quality of the combustion. If it is
very dark, black, the combustion has too little air. The
damper should then be opened more. If the combustion
is good, the soot is greyish brown. When firing with
wood with 18% moisture content, the opening must be
approximately 0.16 in.
Inner ash hatch
The figures below show the insertion of the inner ash
hatch. It is removed in reverse order. It is very important
for the inner ash hatch to be correctly positioned after
sweeping.
Ensure that the inner ash hatch is correctly posi-
tioned.
