Descripción de la invenciónDescription of the invention

Para ello y a partir de las clásicas cámaras de combustión y de post-combustión, en el reactor que se preconiza la entrada de comburente, es decir de aire, se realiza entre el reactor primario y un tubo de aspiración de gases de post-combustión.To do this and from the classic cameras of combustion and post-combustion, in the reactor that the combustion inlet is recommended, that is, air is made between the primary reactor and a gas suction tube of post-combustion

Los gases de post combustión se evacuan de la cámara de post-combustión por el tubo de aspiración concéntrico.Post combustion gases are evacuated from the post-combustion chamber by the suction tube concentric.

La cámara de combustión, que recibe el combustible, está atravesada por el reactor primario.The combustion chamber, which receives the fuel, is crossed by the primary reactor.

El reactor primario está agujereado con orificios que permiten el contacto del combustible con el comburente.The primary reactor is bored with holes that allow fuel contact with the oxidizing

Para complementare la descripción que se está realizando se adjunta un juego de figuras en el que se ha representado lo siguiente:To complement the description that is being performing a set of figures in which it has been represented the following:

La figura 1 muestra una representación esquemática en alzado lateral y en sección del reactor de combustión y de post-combustión que constituye el objeto de la presente invención.Figure 1 shows a representation schematic side elevation and reactor section of combustion and post-combustion constituting the object of the present invention.

La figura 2 muestra un detalle en perspectiva del reactor, en el que se observa la disposición de los orificios que permiten la comunicación entre el combustible y el comburente.Figure 2 shows a perspective detail of the reactor, in which the arrangement of the holes is observed that allow communication between the fuel and the oxidizing

En las figuras reseñadas se observa como la cámara de combustión (1) es atravesada por el reactor (2), materializada en un tubo provisto de orificios (3) los mostrados en detalle en la figura 2, siendo lógicamente la cámara de combustión (1) la que recibe el combustible a quemar (11).In the figures outlined, it can be seen as the combustion chamber (1) is crossed by the reactor (2), materialized in a tube provided with holes (3) those shown in detail in figure 2, the combustion chamber being logically (1) the one that receives the fuel to burn (11).

En el seno de reactor (2) se establece coaxialmente un tubo (4) de evacuación de gases, y rodeando a dicho tubo (4) el reactor (2) incorpora una entrada de aire (5). Opcionalmente pueden realizarse una o más entradas (6) de aire regulables al final del tubo del reactor primario (2).Within the reactor (2) it is established coaxially a gas evacuation tube (4), and surrounding said tube (4) the reactor (2) incorporates an air inlet (5). Optionally one or more air inlets (6) can be made adjustable at the end of the primary reactor tube (2).

El reactor (2) comunica directamente con la cámara de post-combustión (7), de manera que los gases (8) de la combustión acceden también directamente a dicha cámara de post-combustión (7) tal como se observa en la figura 1 y retornan por el tubo (4) de evacuación de gases hacia la aspiración (9).The reactor (2) communicates directly with the post-combustion chamber (7), so that the combustion gases (8) also directly access said post-combustion chamber (7) as seen in Figure 1 and return through the gas evacuation tube (4) towards the aspiration (9).

El inicio de la combustión se produce mediante aporte exterior de llama, suministrada por un quemador de gas (10), un mazut u otro tipo de energía.Combustion starts by external supply of flame, supplied by a gas burner (10), a mazut or other type of energy.

El reactor primario (2) puede ser cilíndrico, de sección cuadrangular, troncocónico, de sección ovalada, rectangular o en forma de paralepípedo. Lo mismo sucede con el tubo (4) de evacuación de gases.The primary reactor (2) can be cylindrical, of quadrangular section, truncated cone, oval section, rectangular or in the form of a parallelepiped. The same happens with the tube (4) of gas evacuation

La aspiración de los gases quemados (12) puede efectuarse por efecto Venturi o por un sistema de ventilación tradicional del tipo ventilador. Una vez iniciada la combustión puede volverse autónoma por el efecto chimenea.The aspiration of the burned gases (12) can be carried out by Venturi effect or by a ventilation system Traditional fan type. Once the combustion started It can become autonomous by the chimney effect.

De acuerdo con esta estructuración, el funcionamiento del reactor es el siguiente:According to this structuring, the reactor operation is as follows:

El combustible (11) se introduce en la cámara de combustión (1). Al arrancarse inflama por el aporte exterior de llama de forma análoga a como se enciende una hoguera de leña.The fuel (11) is introduced into the chamber of combustion (1). When it starts it inflames by the external contribution of Call in a similar way to how a wood fire is lit.

Por el vacío en la cámara (1) de post-combustión el comburente (aire) se aspira a través de los orificios (5) de admisión del reactor primario y entra en contacto el combustible (11) a través de los orificios (3) realizados en la periferia del reactor primario (2). Las llamas y los gases (8) de combustión llenan la cámara (7) de post-combustión.By the vacuum in the chamber (1) of post-combustion the oxidizer (air) aspires to through the intake holes (5) of the primary reactor and the fuel (11) comes into contact through the holes (3) performed on the periphery of the primary reactor (2). You call them and combustion gases (8) fill the chamber (7) of post-combustion

La reacción de combustión se produce a través de los orificios (3) y se realiza alrededor del tubo (4) de evacuación de gases de post-combustión.The combustion reaction occurs through the holes (3) and is made around the evacuation tube (4) of post-combustion gases.

La combustión participa en el calentamiento del tubo (4) de evacuación de gases.Combustion participates in the heating of gas evacuation tube (4).

El tubo (4) de evacuación de gases, con una mayor temperatura y que atraviesa el interior del reactor primario (2), calienta en la entrada de dicho reactor el comburente (aire) que entra por los orificios (5) de admisión.The gas evacuation tube (4), with a higher temperature and through the interior of the primary reactor (2), the oxidizer (air) heats up at the inlet of said reactor which enters through the intake holes (5).

La combustión se mejora por el calentamiento del comburente.Combustion is improved by heating the oxidizing

Los gases (12) de post-combustión se queman mejor por que pasan por el interior del tubo (4)de evacuación, que está "al rojo", al atravesar el reactor primario (2).The gases (12) of post-combustion burn better because they go through the inside of the evacuation tube (4), which is "at red ", when passing through the primary reactor (2).

Para el ajuste de la combustión, los orificios (3) presentes en el tubo del reactor (2') pueden obturarse en mayor o menor medida, para aumentar o reducir la cantidad de combustible (11) que se pone en contacto con el comburente (aire).For combustion adjustment, the holes (3) present in the reactor tube (2 ') can be sealed more or lesser extent, to increase or reduce the amount of fuel (11) which contacts the oxidizer (air).

Los orificios (5) de entrada de aire al inicio del tubo del reactor primario pueden obturarse mas o menos par aumentar o reducir la cantidad de comburente introducida en el tubo del reactor primario (2).The air inlet holes (5) at the beginning of the primary reactor tube can be sealed more or less evenly increase or decrease the amount of oxidizer introduced into the tube of the primary reactor (2).

El ajuste de la potencia de aspiración de los gases (12) de post-combustión acelera o ralentiza la combustión.The adjustment of the suction power of the post-combustion gases (12) accelerates or slows down the combustion.

Tal como anteriormente se ha dicho, pueden realizarse una o varias entradas (6) de aire regulables al final del tubo del reactor (2) primario para facilitar la post-combustión.As previously stated, they can be made one or several air inlets (6) adjustable at the end of the primary reactor tube (2) to facilitate the post-combustion

La cámara (7) de post-combustión acoge de forma unida herméticamente el tubo del reactor primario (2).The post-combustion chamber (7) tightly welcomes the primary reactor tube (2).

La instalación funciona en posición horizontal, vertical u oblicua, siendo el único requisito el cambio de posición de la carga de la cámara (1) de combustión.The installation works in a horizontal position, vertical or oblique, the only requirement being the change of position of the load of the combustion chamber (1).
