Abstract

The device has an atomizing burner (1) that is in triangular or rectangular form to allow better mixture between fresh air and alcohol vapor while limiting effects edge for the triangular form. A plate (5) is located above the burner for channeling flame above the burner. A space is formed between the burner and the plate for inputting the fresh air, allowing direct supply of unpolluted fresh air to the burner for ignition of the vapor and allowing combustion products located above a flame channeling plate. Spacers are placed to keep a space between the plate and a top part of the burner.

Description

Page 1 Dispositif pour améliorer la combustion d'un brûleur à vaporisation alimenté en alcool à enflammer Domaine technique de l'invention L'invention est relative à un dispositif pour améliorer la combustion d'un brûleur à vaporisation alimenté en alcool à enflammer. TECHNICAL FIELD OF THE INVENTION The invention relates to a device for improving the combustion of an alcohol-fired ignition burner to ignite.

État de la technique De tels dispositifs sont notamment utilisés pour la fabrication de systèmes où les brûleurs constituent des foyers et des cheminées pour lesquels le combustible est de type liquide tel que l'alcool éthylique. Dans les solutions connues, la combustion est réalisée à la surface du liquide et les gaz de combustion sont directement rejetés à l'extérieur. Une telle conception n'est pas satisfaisante pour la sécurité compte tenu du caractère toxique des produits de la combustion (monoxyde de carbone), et ne répond plus aux normes réglementaires qui sont applicables en 2009 (norme NF D35 û 386). State of the art Such devices are used in particular for the production of systems in which the burners constitute fireplaces and chimneys for which the fuel is of the liquid type such as ethyl alcohol. In known solutions, the combustion is carried out on the surface of the liquid and the combustion gases are directly discharged to the outside. Such a design is not satisfactory for safety given the toxic nature of the products of combustion (carbon monoxide), and no longer meets the regulatory standards that are applicable in 2009 (standard NF D35 - 386).

Objet de l'invention L'objet de l'invention consiste à réaliser un dispositif de régulation et d'alimentation de la flamme en air frais, afin d'améliorer la qualité de la combustion. Le dispositif selon l'invention est remarquable en ce qu'il comporte : - Un brûleur de forme triangulaire, afin de permettre l'alimentation maximale de la surface libre de combustible, tout en limitant les effets de bord, - Une plaque située au-dessus du brûleur, afin de permettre la canalisation de la flamme ; - des moyens pour alimenter le brûleur en combustible de façon continue. OBJECT OF THE INVENTION The object of the invention is to provide a device for regulating and supplying the flame with fresh air, in order to improve the quality of the combustion. The device according to the invention is remarkable in that it comprises: a triangular shaped burner, in order to allow the maximum supply of the free fuel surface, while limiting edge effects; top of the burner, to allow the channeling of the flame; means for supplying the burner with fuel in a continuous manner.

L'utilisation d'un brûleur de forme rectangulaire est également possible, les effets de bord sont alors plus importants. The use of a rectangular shaped burner is also possible, the edge effects are then more important.

Le fonctionnement du brûleur est simple : la surface du liquide est disposée au fond du brûleur et la flamme se développe en brûlant les vapeurs d'alcool qui se vaporisent. La plaque placée au-dessus permet de canaliser la flamme et de gêner partiellement la combustion en arrêtant une partie des émanations des produits de combustion. Les ouvertures disposées entre le brûleur et la plaque permettent donc l'entrée d'air frais riche en oxygène pour alimenter la zone de surface libre et permettre la combustion des vapeurs d'alcool. Cette arrivée d'air frais permet également de rebrûler une partie des produits de combustion (phénomène de post-combustion) sous la plaque. Ce « rebrûlage » des produits de combustion permet d'améliorer la qualité de la combustion et donc d'améliorer la production de CO neutre. The operation of the burner is simple: the surface of the liquid is arranged at the bottom of the burner and the flame develops by burning the vapors of alcohol that vaporize. The plate placed above it allows to channel the flame and to partially hinder the combustion by stopping a part of the fumes of the products of combustion. The openings disposed between the burner and the plate thus allow the entry of oxygen-rich fresh air to feed the free surface area and allow the combustion of the alcohol vapors. This arrival of fresh air also makes it possible to burn off some of the combustion products (post-combustion phenomenon) under the plate. This "reburning" of combustion products improves the quality of combustion and thus improves the production of neutral CO.

Selon un mode de réalisation préférentiel, le brûleur est réalisé dans une forme triangulaire et de faible profondeur. Les moyens pour alimenter le brûleur permettent d'alimenter le brûleur de façon continue en fonction de la consommation de combustible. Lors de l'inflammation des vapeurs d'alcool, une flamme se développe au-dessus du brûleur. 2950677 Page 2 Une plaque est disposée au-dessus du brûleur pour permettre la canalisation de la flamme libre et la régulation de l'inflammation. Un espace est maintenu entre le brûleur et la plaque supérieure de canalisation pour permettre l'entrée d'air frais non vicié afin de se mélanger aux vapeurs d'alcool afin de permettre l'inflammation et afin de permettre le rebrûlage des produits de combustion piégés sous la plaque. According to a preferred embodiment, the burner is made in a triangular shape and shallow. The means for supplying the burner make it possible to feed the burner continuously according to the fuel consumption. During the ignition of alcohol vapors, a flame develops above the burner. 2950677 Page 2 A plate is placed above the burner to allow the channeling of the free flame and the regulation of the inflammation. A space is maintained between the burner and the upper channel plate to allow the entry of fresh, non-stale air to mix with the alcohol vapors to allow ignition and to allow the burn-up of the trapped combustion products. under the plate.
