2. DESCRIPTION
The appliance is made up of a series of cast-iron G20
elements joined to one another by a fixed joint, while the seal is
assured by refractory putty. The assembly is supported by tie
rods and nuts located outside the heating body and coated with
a galvanized sheet carter (optional).
The devices are equipped with an integrated air circuit for the
recovery of the heat made up of deflectors (radiant fins) on all
external surfaces of the heating body.
The devices are equipped with a hearth with double
thickness rear part made up of a drilled extractible plate.
Through these holes, pre-heated air gets into the hearth; in this
way, it is possible to achieve a post-combustion with an
increase of the yield and a reduction of emissions of unburnt
gases
.
The fireplace is equipped with a sight door with ceramic glass
(resistant up to 700°C).
This allows a charming sight on burning flames. Moreover, in
this way, any possible leak of sparks and smoke is avoided.
The heating of the room occurs:
a) by convection: the passage of air through the
coating and the covering hood releases heat in the
room.
1) by radiation: through the sight glass and the steel
body, heat is radiated into the room.
The device is equipped with registers of primary and
secondary air, with which it is possible to adjust the
combustion air.
1- Primary air register (Figure 1)
With the air register located under the door of the hearth
(on the left), it is possible to adjust the air flow through
the ash drawer and the grating in direction of the fuel.
The primary air is necessary for the combustion process.
The ash drawer has to be emptied regularly, so that ash
cannot hinder the intake of primary air for the
combustion. Primary air is also necessary to keep fire
live.
During the combustion of wood, the primary air
register must be opened only a few, since otherwise the wood burns quickly and the device can
overheat.
