Objeto de la invención Object of the invention
El objeto al cual se refiere la invención que se pretende patentar se define mediante la siguiente descripción, lo cual no pretende ser limitativa de su alcance. La presente invención comprende un novedoso y práctico tubo de evacuación de humos y gases procedentes de estufas, calderas, chimeneas y similares de cualquier tipo y forma, creado para un mayor aprovechamiento calorífico de estos humos y gases residuales.  The object to which the invention is intended to be patented is defined by the following description, which is not intended to be limiting of its scope. The present invention comprises a novel and practical pipe for the evacuation of fumes and gases from stoves, boilers, chimneys and the like of any type and shape, created for a greater calorific use of these fumes and waste gases.
En general y como es sabido, los humos y gases desprendidos de la quema de diferentes combustibles son liberados a la atmósfera. La principal ventaja y característica del invento es que utiliza estos residuos en todo su recorrido hasta su liberación, aprovechando la temperatura de los mismos y suministrando una mayor cantidad de calor.  In general and as is known, the fumes and gases released from the burning of different fuels are released into the atmosphere. The main advantage and characteristic of the invention is that it uses these wastes throughout their travel until they are released, taking advantage of their temperature and providing a greater amount of heat.
El invento se caracteriza esencialmente por comprender un tubo de salida de humos y gases y, al menos, otro tubo de circulación de aire situado en su interior, que queda rodeado en todo su recorrido por esos humos y gases residuales que calientan el aire del tubo interior y situándose la salida de aire caliente por encima de la entrada, por lo que se crea una circulación de aire por convección natural, pudiéndose ayudar con un ventilador o dispositivo similar para dar un mayor caudal de aire, logrando dar un mayor aporte de calor al recinto en el que se encuentre y teniendo la posibilidad de conducir ese aire caliente a otras zonas.  The invention is essentially characterized by comprising a flue and gas outlet pipe and, at least, another air circulation tube located in its interior, which is surrounded throughout its route by those fumes and waste gases that heat the tube air inside and placing the hot air outlet above the inlet, so that a natural convection air circulation is created, being able to help with a fan or similar device to give a greater air flow, managing to give a greater heat input to the enclosure where you are and having the possibility of driving that hot air to other areas.

Estado de la técnica  State of the art
Existen diferentes dispositivos que aplican diversas soluciones con el fin de optimizar el rendimiento calorífico de la quema de los diferentes combustibles.  There are different devices that apply various solutions in order to optimize the calorific efficiency of burning different fuels.
Los tubos de evacuación existentes, similares al invento que aquí se presenta, proporcionan calor por irradiación, concentrando el mismo en los lugares más cercanos a estos dispositivos. Con el invento objeto de la solicitud se consigue un gran aporte calorífico al recinto por el mayor caudal de aire caliente que se produce con el aprovechamiento del calor de los humos y gases residuales que, en otro caso, se liberarían sin ser aprovechados.  Existing evacuation tubes, similar to the invention presented here, provide heat by irradiation, concentrating it in the places closest to these devices. With the invention object of the application a great calorific contribution to the enclosure is achieved by the greater flow of hot air that is produced with the use of the heat of the fumes and residual gases that, in another case, would be released without being used.
La gran mayoría de las soluciones se basan en la mejora de los diseños de las propias estufas, calderas y similares.  The vast majority of the solutions are based on the improvement of the designs of the stoves, boilers and the like.
Otras lo hacen mediante la instalación de tubos de salida de humos específicos para un determinado tipo de estufas como el dispositivo calefactor descrito en el modelo de utilidad ES-1074672_U.
