TITOLO TITLE
CANNA FUMARIA CON SCAMBIA TORE DI CALORE PER CHIMNEY WITH HEAT EXCHANGE FOR
IL RISCALDAMENTO DEGLI AMBIENTI HEATING OF THE ENVIRONMENTS
DESCRIZIONE DESCRIPTION
Il presente brevetto è attinente al settore del riscaldamento degli ambienti ed in particolare concerne una nuova canna fumaria con scambiatore di calore per il riscaldamento degli ambienti. This patent relates to the space heating sector and in particular concerns a new flue with heat exchanger for space heating.
In molte abitazioni il riscaldamento delle stanze viene effettuato con stufe, destinate appositamente al riscaldamento o utilizzate anche per la cottura dei cibi. In many homes the heating of the rooms is carried out with stoves, intended specifically for heating or also used for cooking food.
Sostanzialmente le stufe sono costituite da una camera di combustione e sono dotate di canna fumaria per l'espulsione dei fumi della combustione. Basically the stoves consist of a combustion chamber and are equipped with a flue for the expulsion of combustion fumes.
Il calore generato dalla combustione viene in parte irradiato dalla stufa ed in parte viene trasportato dai fumi della combustione tanto che anche la canna fumaria si riscalda e irradia anch’essa una relativa quantità di calore. The heat generated by combustion is partly radiated by the stove and partly carried by the combustion fumes so that the flue also heats up and also radiates a relative amount of heat.
Nel caso di ambienti molto grandi sono necessarie più stufe per avere uniformità di temperatura nelle varie zone della stanza. La quasi totalità del calore trasportato dai fumi di combustione viene perso nell’ atmosfera con detti fumi di combustione. In the case of very large rooms, several stoves are required to have temperature uniformity in the various areas of the room. Almost all of the heat transported by the combustion fumes is lost in the atmosphere with said combustion fumes.
Da ciò ne consegue che il calore realmente utilizzato per il riscaldamento dell’ambiente è molto minore del calore generato dalla combustione. From this it follows that the heat actually used for heating the environment is much less than the heat generated by combustion.
Oggetto del presente brevetto è una nuova canna fumaria che utilizza il calore trasportato dai fumi di combustione per riscaldare ulteriormente l’ambiente interno. The subject of this patent is a new flue that uses the heat transported by the combustion fumes to further heat the internal environment.
La nuova canna fumaria è costituita nelle sue parti principali da due tubi concentrici dei quali quello interno e passante e quello esterno e chiuso alle sue estremità ed è dotato di due aperture di collegamento (raccordi). The new flue consists in its main parts of two concentric pipes of which the internal one is passing and the external one is closed at its ends and is equipped with two connection openings (fittings).
Ciascuna delle due aperture del tubo esterno è localizzata sulla superficie laterale di detto tubo in prossimità di una sua estremità. Each of the two openings of the outer tube is located on the lateral surface of said tube near one of its ends.
E’ prevista una ventola o altro mezzo di ventilazione forzata che preleva l’aria dall’ambiente circostante la stufa e lo insuffla all’interno dall’ apertura inferiore. A fan or other means of forced ventilation is provided which draws the air from the environment surrounding the stove and blows it inside from the lower opening.
Fra il tubo esterno ed il tubo interno è presente una lamina elicoidale che realizza un percorso obbligato per l'aria insufflata fra i due tubi e fra le due aperture del tubo esterno. Between the outer tube and the inner tube there is a helical lamina which creates an obligatory path for the blown air between the two tubes and between the two openings of the outer tube.
La nuova canna fumaria così costituita sostituisce in tutto o in parte la canna fumaria immediatamente superiore alla stufa; l’uscita superiore del tubo interno della nuova canna fumaria viene collegato con la restante parte della canna fumaria che adduce i fumi della combustione all’esterno. The new flue thus constituted replaces in whole or in part the flue immediately above the stove; the upper outlet of the internal pipe of the new flue is connected with the remaining part of the flue which brings the combustion fumes to the outside.
I fumi della combustione emessi dalla stufa transitano nel tubo interno della nuova canna fumaria cedendogli buona parte di loro calore. The combustion fumes emitted by the stove pass through the internal pipe of the new flue, giving it a large part of their heat.
L’aria insufflata fra il tubo esterno ed il tubo interno percorre tutto il tragitto a spirale definito dalla lamina fra i due tubi e fuoriesce dall’apertura superiore. Durante il tragitto a spirale detta aria insufflata riceve il calore dal tubo interno e riscalda l’ambiente interno quando fuoriesce dall’apertura superiore della nuova canna fumaria. The air blown between the outer tube and the inner tube runs along the entire spiral path defined by the foil between the two tubes and comes out from the upper opening. During the spiral path, said blown air receives heat from the internal pipe and heats the internal environment when it comes out from the upper opening of the new flue.
E’ possibile prevedere che detta apertura superiore della canna fumaria sia collegata con un tubo o condotto che convoglia l’aria riscaldata dalla nuova canna fumaria in un altro ambiente interno. La nuova canna fumaria così come sopra descritto permette di recuperare parte del calore che altrimenti verrebbe disperso all’esterno per riscaldare l’ambiente interno in cui si trova la stufa o un altro ambiente interno. It is possible to provide that said upper opening of the flue is connected with a pipe or duct that conveys the heated air from the new flue to another internal environment. The new flue as described above allows to recover part of the heat that would otherwise be dispersed outside to heat the internal environment in which the stove is located or another internal environment.
I fumi di combustione non risentono negativamente dell’abbassamento di temperatura in quanto la quantità di calore ancora trasportato da detti fumi di combustione non impedisce l’effetto camino. The combustion fumes are not negatively affected by the lowering of temperature as the amount of heat still transported by said combustion fumes does not prevent the chimney effect.
L’aria riscaldata con la nuova canna fumaria può agevolmente riscaldare un’altra stanza non direttamente esposta alla stufa. Nella tavola allegata viene presentato, a titolo esemplificativo e non limitativo, una pratica realizzazione del trovato. The air heated with the new flue can easily heat another room not directly exposed to the stove. In the attached table, a practical embodiment of the invention is presented by way of non-limiting example.
La figura rappresenta la nuova canna fumaria, in parte sezionata, composta da un tubo interno (1) in cui fluiscono i fumi della combustione, da un tubo esterno (2) che avvolge concentricamente il tubo interno (1), una lamina a spirale (3) compresa fra il tubo esterno (2) ed il tubo interno (1). The figure represents the new flue, partly sectioned, consisting of an internal pipe (1) in which the combustion fumes flow, an external pipe (2) that concentrically envelops the internal pipe (1), a spiral sheet ( 3) between the outer tube (2) and the inner tube (1).
Le estremità del tubo esterno sono chiuse a meno di due aperture (2.1, 2.2), una inferiore (2.1) ed una superiore (2.2) presenti sulla superficie laterale del tubo esterno (2). The ends of the outer tube are closed to less than two openings (2.1, 2.2), one lower (2.1) and one upper (2.2) present on the lateral surface of the outer tube (2).
L’aria, eventualmente insufflata da un ventilatore, entra dall’apertura inferiore (2.1), scorre lungo il percorso a spirale lambendo il tubo interno (1) e riscaldandosi, per poi fuoriuscire dall’apertura superiore (2.2) a temperatura più alta. The air, possibly blown by a fan, enters from the lower opening (2.1), flows along the spiral path, touching the inner tube (1) and heating up, and then comes out from the upper opening (2.2) at a higher temperature.
Queste sono le modalità schematiche sufficienti alla persona esperta per realizzare il trovato, di conseguenza, in concreta applicazione potranno esservi delle varianti senza pregiudizio alla sostanza del concetto innovativo. These are the schematic modalities sufficient for the skilled person to realize the invention, consequently, in concrete application there may be variations without prejudice to the substance of the innovative concept.
Pertanto con riferimento alla descrizione che precede e alla tavola acclusa si esprimono le seguenti rivendicazioni Therefore, with reference to the preceding description and to the attached table, the following claims are expressed
