Definitions

  • the present invention concerns a firebox for an apparatus, advantageously, but not exclusively, using biomass or biofuel, of the type provided with a device to control the exit of smoke and fumes from a combustion chamber, when the door of the apparatus is in an open/closed condition.
  • the present invention concerns a firebox provided with filter means able to limit to a minimum the emission into the atmosphere of fine powders, carbon monoxide or other pollutants generated during combustion.
  • a firebox for an apparatus for the combustion of biomass or biofuel in general, connected to a fireplace, a stove, a boiler or similar, having a base structure conformed to define at least a combustion chamber and a chimney for drawing the smoke.
  • the combustion chamber is open at least on one side through a loading or access aperture, hereafter simply referred to as aperture, for example suitable to allow loading from outside the chamber and/or the start of combustion and/or inspection.
  • the aperture may sometimes be selectively closed by means of a door or other similar systems.
  • a choking valve for example a butterfly, normally disposed in a segment of the chimney near the combustion chamber, which serves to choke the transit section of the chimney in order to adjust the free portion of the section on each occasion.
  • a kinematic device is known, for example from the Italian patent IT-B-1310551 , which connects the door to the choking valve so that, when the door is in an open condition, the choking valve too is completely open, and then returns to the desired choking condition, once the door is closed.
  • the filter is disposed along the chimney in suitable zones to obtain the functioning in the above temperature range. Very often these positions are difficult to access for operators, further complicating maintenance interventions.
  • One purpose of the present invention is to obtain a firebox-chimney system for biomass or biofuel in general, but not exclusively intended for this type of fuel, which is both simple and economic to produce.
  • Another purpose is to obtain a firebox-chimney system which allows both a desired and controlled choking of the section of the chimney, and a safe and controlled discharge of the smoke when the door is open.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a firebox-chimney system comprises a base structure conformed to define at least a combustion chamber and a chimney for the smoke which is open, on one side, toward the combustion chamber and, on the other side, toward the outside environment.
  • the combustion chamber is open on at least one side through an aperture which can be selectively closed by means of a door.
  • the chimney comprises at least a segment of flue cooperating with the combustion chamber.
  • the segment is provided with a first pipe and a second pipe for the passage of smoke.
  • the first pipe is associated with choking means so as to choke, in a desired and controlled manner on each occasion, the useful section for the smoke to pass
  • the second pipe is associated with filter means located, according to the direction of the smoke from the combustion chamber toward the outside, before the first pipe merges with the second pipe.
  • connection means are suitable to connect the door with the choking means, so that when the door is open the choking means are automatically in the condition of maximum opening. In this condition the maximum drawing of the smoke through the chimney is guaranteed, avoiding peaks of powders and ash toward the chimney and the exit of the smoke through the aperture.
  • connection means are at least partly kinematic.
  • connection means are at least partly electric or electromechanical, so that the opening of the door drives a control and command circuit which governs the opening of the choking means of the chimney.
  • connection means can at least be partly driven in a pneumatic mode.
  • the first pipe defines the proper channel for the passage of the smoke, while the second channel is placed around the first, that is, surrounding the first pipe, coaxially for example, to define a toric or circular space.
  • the first pipe is associated with the second pipe in the form of a by-pass, that is, one is externally adjacent to the other.
  • the filter means are disposed inside the circular space.
  • the filter means are present in the second pipe.
  • the filter means are found in an accessible position in proximity to the combustion chamber.
  • the filter means are in a zone where the temperature of the smoke always guarantees an operativeness between about 250°C and about 450°C, and they do not influence the functionality of the choking means.
  • the filter means comprise a rapid attachment mechanism, for example of the snap-in type, the bayonet or other type, in order to promote the replacement or maintenance interventions.
  • the snap-in attachment mechanism is made, with a first connection part, on the filter means, and with a second connection part, on an internal wall of the combustion chamber, in correspondence with the aperture of the chimney toward the combustion chamber.
  • the first connection part and the second connection part are configured to cooperate reciprocally on a common lying plane transverse to the direction defined by the path of the smoke along the first pipe and the second pipe.
  • the first connection part is also suitable to cooperate tangentially in rotation with the second connection part to selectively pass from an axially released condition to a condition where it is axially engaged with the internal wall of the chamber.
  • the filter means can be selectively assembled and disassembled inside the circular space, intervening from inside the combustion chamber and acting on a simple snap-in attachment mechanism and performing a simple rotation operation and axial insertion/extraction, without the risk of damaging the filter by dropping it or through accidental knocks.
  • the snap-in attachment mechanism is of the bayonet type in which the first part comprises two fins which protrude laterally from the filter means, whereas the second part comprises two brackets attached to the internal wall and defining with the latter respective housing seatings for the fins of the filter means.
  • the brackets are made directly by shaping the internal wall of the combustion chamber.
  • the assembly of the filter means provides a first step of inserting the filter means inside the annular space, with the fins in a position angularly offset with respect to the brackets. Once a condition of complete insertion has been achieved, the filter means are rotated with respect to their median longitudinal axis, until the fins are taken inside the relative housing seatings.
  • the filter means are easily disassembled from the annular space.
  • This solution also allows the final user to intervene directly in operations to replace, regenerate and/or clean the filter means, without needing the intervention of specialized personnel.
  • the snap-in attachment mechanism is of the elastic type, that is, with an elastic seal of the filter means when the latter are in position inside the annular space.
  • a suitable control and command system drives the choking means which open the first pipe making the smoke, the powders and the ash pass through the first pipe, whereas when the door closes the choking means close the first pipe and the smoke, the powders and the ash transit, at least most of them, through the filter means.
  • the filter means are at least partly of the mechanic type.
  • the filter means are at least partly of the catalytic type.
  • the filter means are mechanical and/or mixed means, so that there are mechanical means located toward the flame and catalytic means located toward the exit of the chimney.
  • the filter means are at least partly electrostatic.
  • the filter means are of the catalytic type, their position will be such that the temperature of the smoke which passes through the filter means maintain the filter means between about 250°C and about 450°C.
  • Positioning the filter means in proximity to the combustion chamber allows to provide quicker and simpler intervention steps, with consequent reduction in maintenance costs while an optimum operativity of the filter means is guaranteed, and also the complete drawing of the smoke from the chimney, when the door is open.
  • the number 10 indicates in its entirety a firebox for a chimney, a stove, a boiler or similar.
  • the firebox 10 comprises a base structure, or frame 11, having a conformation such as to define a combustion chamber 12 and a chimney 13.
  • the combustion chamber 12 is open toward the outside through a loading or inspection aperture 15; the aperture 15 can be selectively closed using a door 16, in this case with a guillotine movement.
  • the chimney 13 is open and on one side faces toward the combustion chamber 12 through an internal wall 17 and on the other side toward the external environment.
  • the chimney 13 comprises, at least in an initial part toward the combustion chamber 12, a first pipe 19 and a second pipe 20, which can be disposed one surrounding the other, advantageously coaxial to each other, or adjacent in a by-pass configuration, that is, not included one inside the other, the first solution in which they are advantageously coaxial is preferred, also aesthetically.
  • the first pipe 19 defines its own channel 19a for the passage of smoke.
  • the first channel 19 has a reduced diameter compared to the second pipe 20.
  • the firebox 10 also comprises, a choking valve 21, for example a butterfly valve, disposed in cooperation with the channel 19a, so as to allow the selective variation of the useful section passage.
  • a choking valve 21 for example a butterfly valve
  • the choking valve 21 can be selectively driven using actuator means 21a.
  • connection means are suitable to connect the door 16 with the choking valve 21, so that when the door 16 is open, the choking valve 21 is in a condition of maximum opening.
  • connection means which drive the choking valve 21 in connection to the door 16 can be a kinematism 22, as shown in fig. 2 , connected to the door 16 and also having, or not, partial adjustment means.
  • connection means which drive the choking valve 21 can be an electric, electromechanical or pneumatic system which provides an opening/closing sensor for the door 16 and in which, by means of a member, for example of the electric suction type, said sensor pilots the closing/opening of the choking valve 21.
  • the firebox 10 also comprises a filter 23, which is associated, or not, with a mechanical filter mean, for example a mesh.
  • the filter 23 is located, according to the direction of the smoke from the combustion chamber 12 toward the outside as shown by the arrows F in figs. 1a and 1b , before the first pipe 19 merges with the second pipe 20.
  • the filter 23 is of the catalytic type.
  • the filter 23 has an alveolar conformation, that is a honeycomb conformation.
  • the filter 23 is suitable to filter both the fine powders, for example PM1 and PM10, and also the volatile organic components, for example OGC, and also to reduce the carbon monoxide (CO), all of which are generated during combustion.
  • the fine powders for example PM1 and PM10
  • the volatile organic components for example OGC
  • CO carbon monoxide
  • the filter 23 comprises a support ring 25 disposed externally, and from which two attachment fins 26 branch off radially and in diametrically opposite positions.
  • the firebox 10 comprises two attachment brackets 27 which are able to define respective housing seatings suitable to couple the attachment fins 26.
  • the housing seatings are open laterally to allow a lateral insertion of the attachment fins 26 inside them.
  • the attachment fins 26 and brackets 27 cooperate reciprocally on a common lying plane, transverse, advantageously perpendicular, with respect to the direction of travel of the smoke along the pipes 19, 20, in the example with respect to the median axis of the chimney 13.
  • the fins 26 are configured to cooperate tangentially in rotation with the attachment brackets 27 in order to pass from a condition axially released from the internal wall 17 to a condition axially engaged, that is, constrained, to the internal wall 17 and vice versa.
  • the filter 23 is configured to be housed in the toric space 20a, providing, to that end, a through aperture 23a, for example in a central position, in which the first pipe 19 ( fig. 1a ) is housed.
  • the filter 23 has a cylindrical shape and a cross section substantially equivalent to the cross section of the space 20a, so as to substantially occupy all the useful section for the passage of the smoke.
  • the filter 23 is instead solid and its position, cooperating with the whole section of the second pipe 20, intercepts all of the smoke or a part of it, depending on the condition of the choking valve 21, which possibly passes through the second pipe 20.
  • the assembly or vice versa the dis-assembly of the filter 23, in the space 20a according to the variant in fig. 1a , or in cooperation with the whole section of the second pipe 20 as in the by-pass variant in fig.
  • the filter 23 is thus correctly positioned inside the space 20a, as in the second variant of fig. 1b the filter 23 is correctly positioned inside the second pipe 20, carrying out, in each case, its functions of filtering the smoke coming from the combustion chamber 12.
  • the smoke can only pass through the space 20a, in the first variant, or through the second pipe 20 in the second variant, and then through the filter 23 in a closed condition of the choking valve 21, or both through the space 20a and through the channel 19a, in the first variant, or through the second pipe 20 and through the first pipe 19 in the second variant, in a open or semi-open condition of the choking valve 21.
