Description
The present invention concerns a stove with solid fuel,
working as a boiler for a heating system.
As it is already well known, the stove is an apparatus for
the conversion of energy into thermic and usually is
different from other devices for heating, like boilers, war
air generators and similar, because it is conceived for
releasing heat through its shell.
Even if it has the same function of local heating, the stove
is different from the fireside, where the furnace or mouth
and the flue and the cowl are usually obtained in the
thickness of the wall of the room to be heated.
The art already known fireplaces working as a boiler:
Italian patents nos. 1067126 and 1060348, in the name of
Giuseppe GABELLINI, relate to fireplace-boilers. Each
boiler of this kind consists of an assembly of one or more
metal walls, provided with a hollow space for the water
circulation and with a plurality of copper coils with a
spiral performance which are in communication with the
wall(s) and are suspended on a water circulation grating
and on a metal bottom, also provided with a hollow space.
Such boiler is placed in a wall or angle fireplace. At the
top of the coils a tubular boiler is provided for the
production of warm water for sanitary use and similar,
which also is touched by the flames produced by the solid
fuel burning on the grating, inside the fireplace. Besides a
small front cowl, the boiler has no other closing means.
Even if its working is rather satisfactory, above
mentioned stove may not be used separately from a
fireplace as moreover it is not provided with a limited
furnace and with its own flue.
Document EP-A-0 072 530 discloses a stove working as a boiler for a heating
system comprising a housing inside which a heat exchanger is provided above
the combustion chamber for the exploitation of the heat of the smokes.
Stoves are also already known as mentioned in US-A-204 518 showing, above the furnace,
a hollow space for the water circulation, crossed by
vertical flues. This solution has a reduced thermic yield
as well as problems deriving from the frequent
obstructions of the flues due to soot and to the difficulty
of cleaning them.
The stove according to the present invention aims to
solving above mentioned inconveniences, realizing an
apparatus for the local heating that combines the pleasure
of a furnace, even where no corresponding fireplace has
not been provided, to the advantages of a central heating.
The present invention makes possible, on one side, the use
of the heat with controlled combustion for the local
heating as well as for the central heating with high thermic
power, and on the other side an easy maintenance and
cleaning of the heating device.
The stove with solid fuel working as a boiler for a heating
system according to the present invention consists of a stove according to claim 1.
The present invention will be described more in detail
hereinbelow relating to the enclosed drawings in which
some embodiments are shown.
Figure 1 shows a front view of a stove with solid fuel
functioning as a boiler for a heating system, according to one embodiment of
the present invention.
Figure 2 shows an axonometric exploded view of the stove
of figure 1, comprising a first heat exchanger provided
inside the same.
Figure 3 shows an axonometric view of a sheaf of pipes of
a second heat exchanger of the stove according to the embodiment of the
present invention.
Figure 4 shows a longitudinal section of the sheaf of pipes
of figure 3.
Relating to the drawings, figure 1 shows the stove
working as a boiler for a heating system according to the
present invention, without all those details and
accessories concerning the heating system as they are
conventional.
In the figures, 1 shows the shell of a stove with solid
fuel, usually firewood; in the embodiment described, said
shell has the shape of a parallelepiped, comprises a single
room and comprises a furnace 2 at the bottom. The stove,
preferably out of metal, is of the so-called all-over
structure, which means that in use, the furnace is filled
with fuel and the combustion takes place progressively in
the whole mass.
Said shell 1 shown in front has in correspodence with said
furnace 2 a wing 3 for introducing firewood, coal or any
other solid fuel. Said wing 3, which has a transparent
panel 30, preferably out of thermic glass, is mounted in a
frame 10 showing slits 12 for the air inlet from the room
into the furnace 2 according to the arrows in figure 2.
Said shell 1 ends up at the top in a tapered connection 11,
preferably in the shape of a truncated pyramid, to a flue
(not shown) with means 13 for the adjusting of the
draught provided thereinbetween.
According to one embodiment of the present invention, a first heat exchanger 5
is provided in a portion 4 of the internal space of the shell
1, between the furnace 2 and the portion limited by said
connection 11.
The heat exchanger 5 consists of a sheaf of pipes with
horizontal development (figure 2) which, in said portion 4
of said shell 1 into which it is housed, is touched by the
flames and by the fumes produced in said furnace 2. Said
portion 4 is closed in front with a panel 6 that can be
removed from said shell 1.
The heat exchanger 5 has headers 5e and 5u, respectively
for the inlet and the outlet of the circulating water,
which are being connected with connections 7e and 7u of a
central heating, which is not shown.
The headers 5e and 5u also work as supporting means for
the whole sheaf of tubes on corresponding sliding and
resting guides 8, which are linked inside said shell 1
along
its circumference. The heat exchanger 5 has a stiffening
frame 5i, the lower sides whereof are resting onto
corresponding supporting rods 9.
Furthermore, and still according to the embodiment of the present invention,
the first heat exchanger 5 is linked to a second sheaf of
pipes 50 with horizontal development (figures 3 and 4),
placed inside a parallelepiped box 51 (figure 2) at the
bottom of said shell 1 of the stove and in contact with the
same. The assembly of the second sheaf of pipes 50 and of
the box 51 forms a second heat exchanger 55 for the warm
water production for sanitary use. The second exchanger
55 receives warmth also due to the air convection and due
to the conduction from the shell 1 of the stove.
The advantages of the stove-boiler according to the
present invention, with respect to the known fireplace-boiler,
are considerable. As the combustion may take
place in a closed room - by closing the wing - it may
take place slowlier and in a controlled manner according
to the kind of fuel used, to the temperature locally
required, i.e. near the stove and in the other rooms that
are to be heated by the central heating to which the first
heat exchanger 5 belongs. In an embodiment according to
the present invention, the measure taken by two
thermocouples connected to digital thermometer,
respectivel upstream
and downstream of a sheaf of pipes of 22 cm length of the
heat exchanger 5, showed a temperature gradient of about
700°C and supplies an evaluation - even if only
qualitatively - of the heat exchange that takes place in
said exchanger and therefore of the power of the stove-boiler
according to the present invention. The quantity of
heat transmitted to the heating system is so high that the
temperature in the expansion container causes the boiling
of the water contained therein, thus suggesting to limit
the combustion mass.
With respect to the fireplace-boiler, the presence of a
completely closed space inside the stove supplies, besides
economy in combustion, a complete safety against casual
sprinkling of sparks onto curtains, carpets and other
inflammable furniture. Furthermore, fumes and soot are
not dispersed in any room of the house.
It will always be possible to maintain the heat exchange
efficient, because the sheaf of pipes of the heat exchanger
5 may be cleaned easily and whenever required. Infact,
after having unscrewed the connection between the links
7e and 7u and the respective headers 5e and 5u, closed for
preventing the outlet of the water contained in said sheaf
of pipes, the latter may slide horizontally once an angular
100 has been removed (figure 2).
Opposite to the sheaf of pipes with vertical development
in the known embodimens mentioned above, the yield of
the stove-boiler according to the present invention is so
high because the flames themself touch the sheaf of pipes
of the exchanger 5 in any pipe.
With respect to the boiler of the fireplace-boiler, the
main advantage of the stove according to the present
invention consists in the better yield of the second heat
exchanger 55 which allows a greater carriage of warm
water as it has a greater surface for the thermic
exchange.
Furthermore, and according to above specification, the
inlet of combustion air into the stove according to the embodiment of the
present invention may sometimes not be able to feed all
firewood: as it must pass close to the inside of the metal
bottom onto which said firewood is placed, it may
oxygenate only the passages obtained in the arrangement
of the pieces.
Therefore, a possible variant according to the present
invention provides the use of three supports placed below
the structure of the stove, for the realization inside the
same of two solid drawers resistant to high
temperatures, with the purpose of favouring the
collection of the ash and at the same time for adjusting
the combustion so that the whole of the firewood rests
onto two strong cast iron gratings embedded in
correspondence with the small drawers below, thus
obtaining the automatic collection of the ash and the
exact adjusting of the combustion speed, operating on the
opening or on the closing.
