El funcionamiento básico del sistema propuesto, trata de aprovechar de manera adicional la llama generada por el quemador, que hasta el momento no se aprovecha de forma directa, absorbiendo el calor a través del intercambiador y mejorando de esta forma el rendimiento de la caldera y por tanto reduciendo el consumo de combustible. The basic operation of the proposed system, tries to take advantage of additionally the flame generated by the burner, which so far is not used directly, absorbing heat through the exchanger and thus improving the performance of the boiler and by both reducing fuel consumption.
El dispositivo se colocará dentro del hogar de la caldera (3, figura 2) a una distancia, que la llama del quemador, incida y entregue la máxima energía. La invención será dimensionada para cada tipo de caldera, y así obtener el mejor rendimiento del sistema. The device will be placed inside the boiler home (3, figure 2) at a distance, that the burner flame, incide and deliver maximum energy. The invention will be sized for each type of boiler, and thus obtain the best system performance.
De la misma forma, se considera la posibilidad de instalar el dispositivo en calderas existentes ylo instaladas, al fondo del hogar de la caldera (3, figura 2), intentando que la modificación sea lo menos invasiva posible, y calculando las dimensiones del dispositivo para cada caso. El montaje implica, el taladro de la parte trasera de la cámara de combustión y posterior sellado, ya sea de hierro ylo de ladrillo refractario, consiguiendo con ello, conectar el dispositivo con la instalación. In the same way, the possibility of installing the device in existing and installed boilers is considered, at the bottom of the boiler's home (3, figure 2), trying to make the modification as invasive as possible, and calculating the dimensions of the device to each case. The assembly involves the drilling of the rear part of the combustion chamber and subsequent sealing, either of iron and refractory brick, thereby connecting the device with the installation.
De esta forma, lanto para calderas nuevas como existentes, el fluido será precalentando antes de su entrada en el intercambiador convencional de la caldera (intercambiador de calor entre los humos de la combustión y el fluido caloportador). Thus, regret for new and existing boilers, the fluid will be preheating before entering the conventional boiler exchanger (heat exchanger between combustion fumes and heat transfer fluid).
Se descubren diversas ventajas en el sistema propuesto, como ya se ha comentado, este dispositivo se podrá instalar en todos los tipos de calderas (gasóleo, biomasa, leña, etc .... ) incluso instalarlo en sistemas de generación de energía térmica, tanto nuevos como existentes.

The machines affected by the device increase their heat output, being able to install thermal power generation machines with higher performance, less emissions, lower fuel consumption and smaller sizes. In addition, it may extend the life of existing boilers in which we install the invention.
Descripción detallada Detailed description
Arrancado el sistema de calefacción y con ello encendiéndose el quemador, la llama incide en el nuevo dispositivo (invención), calentando hasta temperaturas cercanas a los 1.200ºC el revestimiento o placa de material refractario (1 , figura 1), y así calentando o precalentando el fluido que circula por el circuito del intercambiador en contacto con su revestimiento. Once the heating system has been started and with this the burner ignites, the flame affects the new device (invention), heating the lining or plate of refractory material (1, figure 1) to temperatures close to 1,200 ° C, and thus heating or preheating the fluid that circulates through the exchanger circuit in contact with its coating.
El fluido, movido por las bombas de recirculación, entra al intercambiador por su conexión r1 (figura 2) desde el retomo de la instalación, saliendo fluido precalentado (agua, fluido de la instalación, ...) por la conexión sl y conectimdose a la r2 (figura 2). En el caso de calderas diseñadas con el nuevo sistema de precalentamiento de fluido caloportador se estudiarian diferentes formas y maneras de conexionado del sistema a las mismas. The fluid, moved by the recirculation pumps, enters the exchanger through its connection r1 (figure 2) from the return of the installation, leaving preheated fluid (water, installation fluid, ...) through the sl connection and connect to R2 (Figure 2). In the case of boilers designed with the new heat transfer fluid preheating system, different ways and ways of connecting the system to them would be studied.
Se observa, que la invención además de precalentar de forma directa el fluido, crea en el hogar, debido a la pieza refractaria, un calor residual mayor del establecido, proporcionando el aumento del tiempo parada del quemador, y mejorando la combustión y así conseguir otras ventajas y ahorros energéticos. It is observed that, in addition to directly preheating the fluid, the invention creates, in the home, due to the refractory piece, a residual heat greater than that established, providing the burner downtime increase, and improving combustion and thus achieving other advantages and energy savings.
Cuando la instalación llega a su temperatura de consigna, la caldera y las bombas se apagan, pudiendo producir un sobrecalentamiento del fluido y causar sobrepresiones en los circuitos de la instalación, saltando la válvula de seguridad que poseen estas instalaciones, además de dañar y/o deteriorar el intercambiador del sistema propuesto (2, figura 1). Para solucionar este posible When the installation reaches its setpoint temperature, the boiler and the pumps are turned off, which can cause the fluid to overheat and cause overpressures in the installation circuits, bypassing the safety valve that these facilities have, in addition to damaging and / or deteriorate the exchanger of the proposed system (2, figure 1).
