WORKING OF THE THERMAL COOKER
During the working, inside the thermal cooker hap-
pens a combustive reaction of combustible (the
wood inserted in the combustion chamber) and
comburent (the oxygen present in the air of the
room in which the thermal cooker is placed). The
wood fired thermal cooker makes an intermittent
combustion: after the lighting, the combustion
goes on till the exhaustion of the combustible but
it can be maintained lighted by making another
load of combustible and so on. The maintenance of
the combustion in time is guaranteed by the cor-
rect working of the chimney, which allows to evac-
uate the fumes and in the same time to feed the
flame with comburent air. In this way, the features
of the chimney have a big influence on the correct
working of the thermal cooker. The combustion of

Compliant to the indication on the data
label of the pump
wood requests that the air flow inside the combus-
tion chamber happens in different points to obtain
the maximum efficiency. In particular, it is present
a primary air feeding that flows in the lower part
of the combustion chamber by the grill, and one or
more secondary air feedings that flow in the upper
part of the combustion chamber. The primary air is
the main air and regulates the combustion speed.
The secondary air allows the post-combustion of
the fumes, generating further heating, knocking
down the amount of harmful gas and so improving
both the rendering and the impact on the environ-
ment. Once started the combustion it cannot be
interrupted in a safe way: it must be always faded
out naturally with the exhaustion of all the com-
bustible inserted.
