TITOLO TITLE

Bruciatore a combustibile solido, amovibile, per camini e stufe CAMPO DI APPLICAZIONE Solid fuel burner, removable, for fireplaces and stoves. FIELD OF APPLICATION

La presente invenzione si riferisce al campo dei bruciatori a combustibili solidi, tra cui il pellet. The present invention refers to the field of solid fuel burners, including pellets.

In particolare il ritrovato in oggetto ? un dispositivo applicabile ad un caminetto domestico, o stufa per produrre fiamma e riscaldare l?ambiente, amovibile. In particular, the invention in question ? a device applicable to a domestic fireplace, or stove to produce flame and heat the environment, removable.

Il trovato ? finalizzato principalmente a trasformare un camino o stufa a legna, in un piccolo impianto domestico idoneo a riscaldare l?ambiente circostante attraverso l?uso di un combustibile solido come il pellet, senza ricorrere a costose opere impiantistiche e/o murarie, e garantendo la costanza dell?alimentazione della fiamma senza un continuo intervento umano. The found ? mainly aimed at transforming a fireplace or wood-burning stove into a small domestic system suitable for heating the surrounding environment through the use of a solid fuel such as pellets, without resorting to costly installation and/or masonry works, and guaranteeing the constancy of feeding the flame without continuous human intervention.

STATO DELLA TECNICA STATE OF THE ART

Attualmente per trasformare un camino di casa in stufa funzionante a combustibile solido e/o pellet, sono necessarie delle istallazioni complesse che prevedono interventi murari, non reversibili senza un intervento qualificato, come i termo camini, oppure esistono nello stato dell?arte bruciatori amovibili, ma privi di tecnologia atta a regolare l?ingresso dell?aria nel bruciatore stesso e quindi a mantenere accesa in modo costante la fiamma e/o a regolarne l?intensit? a seconda delle necessit? ambientali. Currently, to transform a home fireplace into a stove running on solid fuel and/or pellets, complex installations are required which involve masonry interventions, which cannot be reversed without qualified intervention, such as thermo fireplaces, or there are state-of-the-art removable burners, but without the technology suitable for regulating the entry of air into the burner itself and therefore for keeping the flame lit constantly and/or for regulating its intensity? depending on the needs? environmental.

PROBLEMA TECNICO TECHNICAL PROBLEM

Il ritrovato in oggetto, risolve detti problemi (irreversibilit? dell?istallazione e mantenimento e regolazione della fiamma in modo automatico) contemporaneamente, attraverso un dispositivo compatto e leggero che permette a un comune individuo di bruciare efficacemente ed efficientemente combustibile solido come il pellet nel proprio camino di casa per produrre calore, mantenendo accesa la fiamma, regolandone l?intensit? e con la possibilit? di tornare ad usare il caminetto con la comune legna da ardere senza interventi murari. The invention in question solves said problems (irreversibility of the installation and maintenance and regulation of the flame automatically) at the same time, through a compact and light device which allows a common individual to effectively and efficiently burn solid fuel such as pellets in his own home fireplace to produce heat, keeping the flame lit, regulating its intensity? and with the possibility to go back to using the fireplace with common firewood without masonry interventions.

DESCRIZIONE DI UNA O PI? FORME DI ATTUAZIONE DESCRIPTION OF ONE OR PI? FORMS OF IMPLEMENTATION

Per realizzare il suddetto scopo viene descritto un bruciatore comprendente un contenitore (1) chiuso sul fondo e nelle superfici laterali, di qualsivoglia, forma in materiale resistente alle alte temperature (min 500?C) e di dimensioni atte ad essere inserito e posato all?interno di un camino domestico, che ha la faccia superiore aperta ed al cui interno insiste una griglia (2) in materiale resistente alle alte temperature (min 500?C), posta parallelamente al fondo del contenitore (1) e fissata saldamente alle pareti laterali mediante saldatura e/o sistemi a vite e/o rivetti, in posizione intermedia tra il fondo e la faccia aperta superiore. To achieve the aforementioned purpose, a burner is described comprising a container (1) closed on the bottom and on the side surfaces, of any shape, made of material resistant to high temperatures (min. 500°C) and of dimensions suitable for being inserted and placed inside the interior of a domestic fireplace, which has an open upper face and inside which there is a grate (2) made of material resistant to high temperatures (min 500?C), placed parallel to the bottom of the container (1) and firmly fixed to the side walls by welding and/or screw and/or rivet systems, in an intermediate position between the bottom and the upper open face.

Detto contenitore (1) ha un foro (3) sulla parete laterale, in posizione intermedia tra il fondo e la griglia (2) idoneo ad ospitare per incastro, o solidamente fissato, un condotto (4) di lunghezza variabile e/o telescopica, di qualsivoglia materiale e sezione analoga al foro (3), sufficiente al passaggio forzato di un quantitativo d?aria necessario e sufficiente ad alimentare la combustione nel bruciatore. Inoltre, all?estremit? opposta del condotto ? applicato per incastro, o solidamente fissato, un collettore (7) di qualsivoglia materiale conico o di altra forma atta a convogliare nel condotto (1) l?aria spinta da una ventola (5) cui sar? solidamente assemblato, alimentata elettricamente preferibilmente a 12V o 24 V attraverso un trasformatore (8) collegato alla rete elettrica domestica. In fine, la portata d?aria della ventola (5) sar? variabile da 0 ad oltre 80 mc/h attraverso un potenziometro (6) ed una scheda di controllo elettronico. Said container (1) has a hole (3) on the side wall, in an intermediate position between the bottom and the grate (2) suitable for housing, by interlocking, or solidly fixed, a duct (4) of variable and/or telescopic length, of any material and section similar to the hole (3), sufficient for the forced passage of a quantity of air necessary and sufficient to feed combustion in the burner. Furthermore, at the end? opposite of the duct ? a manifold (7) of any conical material or other shape suitable for conveying the air pushed by a fan (5) into the duct (1) to which it will be fitted, by interlocking or solidly fixed. solidly assembled, electrically powered preferably at 12V or 24V through a transformer (8) connected to the domestic electrical network. Finally, the air flow rate of the fan (5) will be? variable from 0 to over 80 m3/h via a potentiometer (6) and an electronic control card.

Detto bruciatore ? ulteriormente descritto nelle rivendicazioni da 1 a 8 che qui si intendono integralmente trascritte. Said burner ? further described in claims 1 to 8 which are hereby understood to be integrally transcribed.

Le rivendicazioni da 9 a 10, cui pure si rimanda e che anche si intendono qui trascritte, descrivono il metodo di funzionamento dell?apparato. Claims 9 to 10, to which reference is also made and which are also understood to be transcribed herein, describe the method of operation of the apparatus.

Pi? in particolare l?utilizzatore porr? tutto l?apparato sopra descritto all?interno di un caminetto con il condotto (4) e la relativa ventola (5) rivolti lateralmente verso un lato aperto del camino, verser? il pellet sfuso sulla griglia del bruciatore, riempiendo il contenitore (1), azioner? alla massima portata la ventola di alimentazione, che spinger? l?aria nella base del bruciatore attraverso il condotto, e innescher? il pellet con una fiamma addotta dall?esterno. In breve tempo il pellet produrr? una fiamma lenta e costante con generazione di calore e pochissimo fumo. Un solo chilogrammo di pellet o altro combustibile solido garantisce fiamma vivida e calore per un tempo pari alla quantit? di combustibile inserito nel contenitore (1), dopo di che va aggiunto altro combustibile. In un esempio concreto in un bruciatore con contenitore idoneo a contenere da 1 a 3 kg di pellet, la fiamma durer? circa 1 ora, alla fine della quale sar? sufficiente aggiungere altro combustibile. Pi? in particular the? user porr? all the apparatus described above inside a fireplace with the duct (4) and the relative fan (5) facing laterally towards an open side of the fireplace, will pour? the loose pellet on the burner grate, filling the container (1), action? at maximum capacity the power fan, who will push? the air in the base of the burner through the duct, and innescher? the pellet with a flame brought in from outside. In a short time the pellet will produce a slow, steady flame with heat generation and very little smoke. A single kilogram of pellets or other solid fuel guarantees a vivid flame and heat for a time equal to the quantity of fuel inserted into the container (1), after which more fuel must be added. In a concrete example, in a burner with a container suitable for containing from 1 to 3 kg of pellets, the flame will last? about 1 hour, at the end of which sar? just add more fuel.

La velocit? di combustione e l?altezza della fiamma si potr? regolare diminuendo o aumentando la portata d?aria della ventola mediante il potenziometro aspettando che il combustibile, pellet, si esaurisca, oppure si potr? spegnere anzitempo il bruciatore spegnendo la ventola e/o coprendo ermeticamente con un coperchio il bruciatore. The speed? of combustion and the height of the flame you can? adjust by decreasing or increasing the air flow rate of the fan using the potentiometer waiting for the fuel, pellets, to run out, or you can? turn off the burner prematurely by turning off the fan and/or covering the burner hermetically with a lid.

VANTAGGI ADVANTAGES

Vantaggi del presente ritrovato sono la facilit? di utilizzo, l?economicit?, la semplicit? dell?istallazione, che non richiede particolari interventi murari, il fatto che il camino o stufa a cui ? applicato possano tornare a essere alimentati a legna, senza ulteriori interventi, ma semplicemente rimuovendo il ritrovato stesso. Advantages of this invention are the ease? of use, the? cheapness?, the simplicity? of the installation, which does not require particular masonry interventions, the fact that the fireplace or stove to which it is connected? applied can go back to being fueled by wood, without further interventions, but simply by removing the invention itself.
