Abstract

The fired heat exchanger is characterised by the fact that it contains a modular block constituting a set of inseparably interconnected panel plates (1) with a combustion chamber located in its upper internal part (2) ensuring full integration of the combustion chamber (2) with the working heat exchange surface located in the lower part of the panel plates (1). This surface is created by the lower lateral surfaces of the panel plates (1) together with chattered lamella bands mounted on them (3). They expand the working heat exchange surface and the gasses created in the combustion chamber (2) flow around this surface. The circulation of the liquid heated medium in the unit of interconnected panel plates (1) has a medium flow velocity within the range 0.5 - 2 m/s and is of a two-stage type. During the first stage, the main process of heat exchange on the working surface takes place. During the second stage, the combustion chamber (2) is cooled by the water jacket constituting the upper part of the panel plates (1).

Description

Intercambiador de calor con cámara de combustión Heat exchanger with combustion chamber

5 [0001] La invención que se describe en el presente documento es un intercambiador de calor con cámara de combustión diseñado para tener su mejor uso en calderas y precalentadores. [0001] The invention described herein is a heat exchanger with combustion chamber designed to have its best use in boilers and preheaters.

[0002] Teniendo en cuenta el estado actual de la tecnología, existen unas soluciones de intercambiador de calor con cámara de combustión bien conocidas y ampliamente utilizadas en las que las cámaras de combustión y las superficies de trabajo para el intercambio de calor consisten en múltiples elementos, lo que hace su estructura más complicada, volviendo su construcción e instalación difíciles. Esta solución da como resultado una superficie de intercambio de calor inferior con respecto a la relación en peso y unas dimensiones más grandes en conjunto a la vez que se mantiene la misma tasa de intercambiador de calor. [0002] Taking into account the current state of the technology, there are well-known and widely used heat exchanger solutions with combustion chamber in which the combustion chambers and work surfaces for heat exchange consist of multiple elements , which makes its structure more complicated, making its construction and installation difficult. This solution results in a lower heat exchange surface with respect to the weight ratio and larger dimensions as a whole while maintaining the same heat exchanger rate.

15 [0003] Un ejemplo de una solución de este tipo es un intercambiador de calor que fabrica la compañía Viessman, de Alemania. Su estructura presenta una cámara de combustión de carcasa cilíndrica a la que se han soldado unas placas con pliegues de forma especial. Estas placas constituyen la superficie de trabajo de intercambio de calor, que crea unas capas mutuamente paralelas separadas una de otra. Los medios que toman parte en el proceso de intercambio de calor fluyen alrededor de las capas en un sentido contracorriente. [0003] An example of such a solution is a heat exchanger manufactured by the Viessman company in Germany. Its structure has a combustion chamber with a cylindrical shell to which plates with special folds have been welded. These plates constitute the heat exchange work surface, which creates mutually parallel layers separated from each other. The media that take part in the heat exchange process flows around the layers in a countercurrent direction.

[0004] El documento EP-A-1 184 628 dio a conocer un intercambiador de calor que tiene una columna de placas que forman cámaras huecas para un medio de calentamiento y cámaras intermedias para un conducto de humos de gas de calentamiento. Las placas forman un cuerpo modular con una cámara integrada para un quemador. Las cámaras de medio de calentamiento y las cámaras de gas de calentamiento se alternan unas con otras. Una placa [0004] EP-A-1 184 628 disclosed a heat exchanger having a column of plates forming hollow chambers for a heating medium and intermediate chambers for a flue gas duct. The plates form a modular body with an integrated burner chamber. The heating medium chambers and the heating gas chambers alternate with each other. A plate

25 tiene unas superficies de flujo para el gas de calentamiento y la otra tiene unas superficies de flujo para el medio de calentamiento. 25 has flow surfaces for the heating gas and the other has flow surfaces for the heating medium.

[0005] Otra desventaja de esta solución actual es la necesidad de soldar las placas a la cámara de combustión con el fin de asegurar su integración completa. Además, la totalidad de la estructura ha de alojarse también en una carcasa diseñada de forma especial, con el fin de asegurar el sellado y el flujo dirigido de forma adecuada del medio entre las placas. [0005] Another disadvantage of this current solution is the need to weld the plates to the combustion chamber in order to ensure their complete integration. In addition, the entire structure must also be housed in a specially designed housing, in order to ensure the sealing and suitably directed flow of the medium between the plates.

45 [0007] La presente distribución asegura una integración completa de la cámara de combustión con la superficie de trabajo de intercambio de calor ubicada en la parte inferior de las placas de panel. La superficie de trabajo de intercambio de calor se crea mediante las caras laterales inferiores de las placas de panel y las bandas con pliegues montadas sobre las mismas. Las bandas expanden la superficie de trabajo de intercambio de calor y los gases que se crean en la cámara de combustión fluyen alrededor de esta superficie. La circulación del medio calentado líquido en la unidad de placas de panel interconectadas tiene una velocidad de flujo del medio dentro del intervalo de de 0,5 [0007] This distribution ensures a complete integration of the combustion chamber with the heat exchange work surface located at the bottom of the panel plates. The heat exchange work surface is created by the lower side faces of the panel plates and the bands with folds mounted thereon. The bands expand the heat exchange work surface and the gases that are created in the combustion chamber flow around this surface. The circulation of the liquid heated medium in the interconnected panel panel unit has a medium flow rate within the range of 0.5
