A post‐combustion provides a good usage of fuel energy and an almost complete
combustion of the toxic and harmful substances from the smoke.
Upon lighting the air flows through the
UCC
and to the flue pipe (chimney). When the stove
reaches a certain temperature the air flow is diverted and the still unburned gasses are lead
from the
UCC
through an opening in the bottom stone plate to the
LCC
. Over the opening is
a steel dome placed.
Flames are thus lead through the opening to the
LCC
for post‐combustion of the gases.
6.2.1 Automatic regulation for combustion air
The stove is equipped with an independent and self‐regulating air damper. Hence there is no
damper handle.
The primary air is added to the primary combustion zone, i.e. the bed of glowing embers. The cold
air is only used in the lighting stage.
Secondary air is added in the gas combustion zone, i.e. air which contributes to the combustion of
the pyrolysis gases (preheated air, which is used for the cleaner glass system and the combustion).
This is air sucked through the damper and is pre‐heated through the side channels and then emitted
as hot scavenging air onto the glass. The hot air rinses the glass and keeps it soot free.
A clean combustion is indicated by clear yellow flames.
The pilot nozzles are placed in the back plate of the upper combustion chamber. They ensure that
the bed of glowing embers is fed with air and therefore holds a high temperature. It provides a quick
start when re‐fuelling and reduces the risk of fire going out.
Important! ‐ during kindling / refuelling
If an ash pan is use, it must be placed
at the bottom on lower combustion chamber.
