Description

OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION

La presente invención se refiere a un recuperador de calof, que actúa como intercambiador térmico para aumentar la energía térmica pmporcionada, por ejemplo, por una caldera de gas de las utilizadas en instalaciones de calefacción. The present invention relates to a heat recovery device, which acts as a heat exchanger to increase the thermal energy supplied, for example, by a gas boiler used in heating installations.

El objeto de la invención es conseguir un mayor rendimiento de una caldera de gas, por calentamiento del agua de retomo, en base a la disposición del equipo recuperador de calor a la salida de gases de dicha caldera, es decir en la chimenea de evacuación de gases. The object of the invention is to achieve a higher performance of a gas boiler, by heating the return water, based on the arrangement of the heat recovery equipment at the gas outlet of said boiler, that is in the chimney of evacuation of gases

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

En la Industria existen diferentes equipos destinados a recuperar calor procedente de salidas de gases en calderas, motores de combustión y fuentes de calor residual, susceptibles de ser aprovechados para incrementar el rendimiento de los propios equipos o transferir la energía ténnica residual para otros usos. In the Industry there are different equipment destined to recover heat from gas outlets in boilers, combustion engines and sources of residual heat, which can be used to increase the performance of the equipment itself or transfer the residual technical energy for other uses.

En cualquier caso se trata de intercambiadores de calor que ponen en contacto dos fluidos y transfieren la energía térmica de un fluido al otro. In any case, they are heat exchangers that bring two fluids into contact and transfer the thermal energy from one fluid to the other.

En algunas ocasiones, en las salidas de chimeneas de calderas, o en escapes de motores, el fluido que cede calor contiene una gran cantidad de vapor de agua que al condensarse sobre las paredes del intercambiador aumenta notablemente la energía térmica cedida. El proceso de condensacíón de ese vapor de a~lua necesita liberar calar necesariamente para que se produzca el cambio de estada, que es abSOrbido por el fluidO que se pretende calentar. On some occasions, at the outlets of boiler chimneys, or in engine leaks, the heat-giving fluid contains a large amount of water vapor which, when condensed on the walls of the exchanger, significantly increases the thermal energy assigned. The condensation process of that water vapor needs to free the draft necessarily in order for the change of state to occur, which is absorbed by the fluid to be heated.

En estos casos se aprovecha el calor latente de cambio de estado. Es el principio utilizado In these cases the latent heat of state change is used. It is the principle used

por las calderas de condensación que alcanzan rendimientos de un 109% beneficiándose y by condensing boilers that reach yields of 109% benefiting and

aprovechando de este modo el poder calorífico superior del combustible empleado. taking advantage of the superior calorific value of the fuel used.

En las calderas Que no son de condensación se puede añadir un módulo en la salida de In the non-condensing boilers a module can be added to the output of

gases llamado umódulo de condensación", que no es más que un intercambiador térmico gases called a condensation umulo, which is nothing more than a heat exchanger

que permite convertir una caldera convencional en una de condensación. which allows converting a conventional boiler into a condensing boiler.

5 REALIZACIÓN PREFERENTE DE LA INVENCIÓN 5 PREFERRED EMBODIMENT OF THE INVENTION

Como se puede ver en las figuras referidas, el recuperador de la invención se constituye a partir de un tubo corrugado (1) enroscado sobre si mismo, tal y como aparece en la figura 1, con un tramo extremo (2) para su conexión al agua de retomo procedente de una 10 instalación de calefacción, presentando así mismo un tramo extremo (3) de salida, conectado a la entrada de agua de recuperación de la propia caldera de gas. Sobre dicho tubo corrugado (1) circulará agua procedentE~ de la comentada instalación de calefacción, como agua de retomo hacia la caldera, saliendo por el tramo extremo (3) hacia dicha caldera, con la especial particularidad de que ese tubo corrugado (1) va situado en un 15 espacio aislante correspondiente a lo que es considerado como primer tramo de la respectiva chimenea de salida de gases conl~ctada a la caldera de gas, con lo que dichos gases pasan entre ese espacio aislante y E~I propio tubo corrugado (1), produciendo el calentamiento del agua que circula por I~ste ultimo 'i por lo tanto aumentando el rendimiento de la caldera, ya que esa agua calentada procedente de la instalación de As can be seen in the aforementioned figures, the recuperator of the invention is constituted from a corrugated tube (1) screwed on itself, as it appears in figure 1, with an end section (2) for its connection to the return water from a heating installation, also presenting an end section (3) of outlet, connected to the recovery water inlet of the gas boiler itself. On said corrugated tube (1) water will flow from the aforementioned heating installation, such as return water to the boiler, leaving through the extreme section (3) towards said boiler, with the particular feature that that corrugated tube (1) it is located in an insulating space corresponding to what is considered as the first section of the respective gas outlet chimney connected to the gas boiler, whereby said gases pass between that insulating space and E ~ I own corrugated pipe (1), producing the heating of the water that circulates through the latter and therefore increasing the boiler's performance, since that heated water from the installation of
