Abstract
Dispositivo de precalentamiento de agua en calderas de combustión.#El dispositivo de precalentamiento de agua está compuesto por un recipiente hermético (1) con un orificio central (13), un intercambiador de calor de tubos paralelos (2) o un intercambiador en espiral (4) y una tapa (3). El recipiente hermético (1) tiene un tratamiento contra la corrosión en el orificio central (13) y un tubo para la salida de los ácidos (14) resultantes del enfriamiento de los gases de combustión. El dispositivo lleva un fluido de transferencia térmica en un circuito cerrado y despresurizado (9).#Los gases de combustión provenientes de la caldera calientan el tubo interior del dispositivo, el cual transmite el calor al fluido de transferencia térmica donde se encuentra sumergido el intercambiador de calor (2 ó 4). Con el calor del fluido de transferencia térmica se calienta el agua que pasa por el interior de los tubos del cambiador de calor, precalentando el agua antes de entrar en la caldera.Water preheating device in combustion boilers. # The water preheating device is composed of an airtight container (1) with a central hole (13), a parallel tube heat exchanger (2) or a spiral exchanger ( 4) and a cover (3). The hermetic container (1) has a corrosion treatment in the central hole (13) and a tube for the exit of the acids (14) resulting from the cooling of the flue gases. The device carries a thermal transfer fluid in a closed and depressurized circuit (9). # Combustion gases from the boiler heat the inner tube of the device, which transmits heat to the thermal transfer fluid where the exchanger is submerged of heat (2 or 4). With the heat of the thermal transfer fluid, the water that passes through the heat exchanger tubes is heated, preheating the water before entering the boiler.

- La presente invención, según se expresa en el enunciado de esta memoria descripliva, se refiere a un disposilivo que acoplado en la salida de humos de una caldera de agua o vapor, uliliza el calor del humo para precalenlar el agua, que posleriormenle al enlrar en la caldera disminuye la rampa lénmica, generando el mismo produclo, agua calienle o vapor pero gaslando menos combuslible en consecuencia generando menos polución. The present invention, as expressed in the statement of this specification, refers to a device which, coupled with the flue gas outlet of a water or steam boiler, uses heat from the smoke to pre-fill the water, which can be used later when listed in The boiler decreases the limestone ramp, generating the same production, hot water or steam but spending less fuel, consequently generating less pollution.
- El dispositivo funciona a partir de un principio termodinámico al trabajar la caldera, los gases calienles pasan por el orificio cenlral, calenlando el fluido de transferencia térmica, que a su vez calienta un intercambiador de calor. The device works from a thermodynamic principle when working the boiler, the hot gases pass through the central hole, heating the heat transfer fluid, which in turn heats a heat exchanger.

El circuito con fluido de transferencia térmica no se encuentra bajo presión, el único sislema con presión de Irabajo es el circuilo de agua. The device is expected to be lolalmenle indepenienle can be used by any boiler (conventional or condensing) that has automatic temperature control or automated steam generators. The circuit with thermal transfer fluid is not under pressure, the only system with low pressure is the water circuit.

- Se conocen algunos dispositivos (chimeneas) por los que discurren los gases calienles provenienles de la caldera de combuslión y se lanzan a la almósfera, la utilización se limita a eliminar los gases para evitar intoxicaciones y tener tratamiento para r~sistir la corrosión. En una caldera domestica convencional los gases salen a una lemperalura media de 140·, en una caldera de condensación salen a una media de 600 y en una caldera industrial de generación de vapor sale a una media de 2500, es decir gran parte del calor generado no es aprovechado, los sislemas de ahorro energélico exislenles en -calderas domesiicas lienen -como -principales dificullades la corrosión del circuilo de agua por los ácidos resullanles del enfriamienlo pues eslán en contacto directo con el mismo y las dimensiones de la caldera que por contener mas disposilivos es mayor que las anliguas y se loma dificil cambiarlas pues las anliguas ya liene su lugar apropiado y acoplado en casa. Some devices (chimneys) through which the hot gases from the combustion boiler run and are released into the atmosphere are known, the use is limited to eliminating the gases to avoid poisoning and having treatment to resist corrosion. In a conventional domestic boiler the gases leave at an average temperature of 140 ·, in a condensing boiler they leave at an average of 600 and in an industrial steam boiler it leaves at an average of 2,500, that is to say much of the heat generated It is not used, energy saving systems exist in domestic boilers have -as -principal difficulties in corrosion of the water circuit by acids resulting from the cooling because it is in direct contact with it and the dimensions of the boiler to contain more The devices are larger than the old ones and it is difficult to change them because the old ones already have their proper place and docked at home.
