Abstract

The economiser is a reflector in the form of an integral hearth (1) and fireback (2,3,4) manufactured from thick steel plate. The principle can be adapted for a fireplace with a fresh air inlet (7) with a regulator for the airflow (8). In houses with other main forms of heating such as electricity, it is desirable to close off the chimney when the fire is out. A damper (10) is installed for this purpose. The system may also be installed to serve as an indirect air heater, with the fresh air passing over the back of the radiant plate before discharging into the room.

Description

DESCRIPTION ÂTRE A RAYONNEMENT. ECONOMISEUR D'ANERGIE POUR CEEMINEE A BOIS
A FEU OUVERT
La présente invention a pour objet un appareil économiseur d'énergie de chauffage, qui, sans nécessiter d'installation spéciale, glissé simplement dans litre d'une cheminée a bois à foyer ouvert, dont le tirage est normal, permet d'améliorer considérablement le rendement thermique utilisable.
DESCRIPTION RADIANT. ANERGY SAVING FOR WOOD FIREPLACE
OPEN FIRE
The subject of the present invention is an energy-saving appliance for heating, which, without requiring any special installation, simply slipped into a liter of an open hearth wood fireplace, the draft of which is normal, makes it possible to considerably improve the usable thermal efficiency.

La mise en régime est rapide, le feu dans litre ne diff & re pas de l'aspect d'un feu ordinaire. The setting in mode is fast, the fire in liter does not differ from the aspect of an ordinary fire.

L'appareil est incassable, inusable et sans entretien. The device is unbreakable, hard-wearing and maintenance-free.

Alors que dane une cheminée ordinaire on n'utilise qu'une très faible partie de la chaleur, celle qui est transmise par rayonnement direct, notre appareil capte la plus grande partie des rayons qui autrefois n'étaient pas utilisée et les dirige dans le local à chauffer. Whereas in an ordinary chimney we use only a very small part of the heat, that which is transmitted by direct radiation, our device collects the greatest part of the rays which formerly were not used and directs them into the room to heat.

Notre appareil est constitué par une seule plaque d'acier traité, de forte épaisseur, 8 à 10 mm, pliée en plusieurs endroits et formant la sole (1), la plaque foyere (2), la plaque rayonnante (3) et le réflecteur (4). Voir dessin 1, planche I/2. Our device consists of a single treated steel plate, very thick, 8 to 10 mm, folded in several places and forming the sole (1), the hearth plate (2), the radiating plate (3) and the reflector. (4). See drawing 1, plate I / 2.

Les dimensions et les angles de pliage 5 et 6 sont variables, suivant les dimensions de l'ouverture du foyer et calculés de façon que les rayons réfléchis autrefois inutilisés puissent pénétrer dans la pièce à chauffer. The dimensions and the folding angles 5 and 6 are variable, depending on the dimensions of the opening of the hearth and calculated so that the previously unused reflected rays can penetrate into the room to be heated.

Dans une cheminée à bois à feu ouvert, les températures les plus élevées sont localisées sous le brasier et dans la partie verticale la plus proche du feu. In an open wood fireplace, the highest temperatures are located under the brazier and in the vertical part closest to the fire.

Le fait que notre appareil se compose d'une seule plaque d'acier de forte épaisseur et qu'il n'y a pas de cassure, permet de répartir par conductivité cet excès de chaleur sur une plus grande surface, ce qui permet l'effet rayonnant. On capte davantage de chaleur sur une plaque disposée obliquement sur un foyer ouvert et on obtient une meilleure récupération lorsque la chaleur des flammes et des gaz léchant cette paroi est réfléchie et dirigée utilement dans le local à chauffer, avant d'être refroidie par l'excès d'air. The fact that our device consists of a single thick steel plate and that there is no breakage, allows to distribute by conductivity this excess heat over a larger surface, which allows the radiant effect. More heat is captured on a plate placed obliquely on an open hearth and better recovery is obtained when the heat of the flames and gases licking this wall is reflected and usefully directed into the room to be heated, before being cooled by the excess air.

La température de la plaque rayonnante améliore la combustion et diminue la fumivosité.  The temperature of the radiating plate improves combustion and decreases the fumivosity.

La chaleur rayonnée de faible longueur d'ondes 8 à 4 est perçue par les occupants beaucoup plus vite que la température ambiante du local qui s'échauffe progressivement, ce qui permet d'apprécier ce chauffage sans néceseiter un fonctionnement continu. The radiated heat of short wavelength 8 to 4 is perceived by the occupants much faster than the ambient temperature of the room which gradually heats up, which makes it possible to appreciate this heating without requiring continuous operation.

ATRE A RAYONNENENT, ECONObilSEUR D'ENERGIE POUR CHEMINERAS A BOI5 Quatre modèles sont prévus et un ventilateur de prise d'air.R E V E N D I C A T I O N S WITH OPEN FIRE. ATRE A RAYONNENENT, ENERGY SAVING FOR CHIMNEYS IN BOI5 Four models are provided and an air intake fan. 1 - Pour cheminée existante dont le tirage est normal 1 - For existing chimneys with normal draft Fig. 1, planche 1/2. Appareil simplement glissé dans litre sans nécessiter d'installation, permet une économie d'environ 60 % pour un chauffage équivalent.Fig. 1, plate 1/2. Device simply slipped into liter without requiring installation, saves around 60% for equivalent heating. 2 - Pour cheminée existante mais en prévoyant une prise d'air extérieure Fig. 2, planche 1/2. 2 - For an existing chimney but with an outside air intake Fig. 2, plate 1/2. L'air nécessaire à la combustion débouche sous la sole 1, se réchauffe légèrement et aboutit en un tiroir souffleur 8, placé à l'avant, qui permet le réglage d'air ou la fermeture Si le feu n'est pas utilisé. The air necessary for combustion opens out under the hearth 1, heats up slightly and ends up in a blower drawer 8, placed at the front, which allows air adjustment or closing If the fire is not used. Pour les deux appareils précédents Fig. 1 et Fig. 2 une jaquette calorifuge incombustible 9 peut notre utilisée sur la face arrière pour obtenir le maximum de rendement. For the two previous devices Fig. 1 and Fig. 2 an incombustible heat insulating jacket 9 can be used on the rear side to obtain maximum performance. 3 - Dans les maisons à chauffage électrique intégré où l'on désire néanmoins pouvoir utiliser utilement un feu de bois, il est indispensable de pouvoir isoler la cheminé, lorsque le feu n'est pas utilisé, par un volet de fermeture placé dans l'avaloir. L'appareil Fig. 3, planche I/2, comporte le dispositif d'alimentation d'air extérieur réglable par tiroir souffleur, la jaquette calorifuge et le volet de fermeture de cheminée 10 réglable par un secteur & rochet 16, le tout assemblé et ajusté par une armature eolide qui facilite la pose et le raccordement au conduit de fumée. 3 - In houses with integrated electric heating where it is nevertheless desirable to be able to use a wood fire in a useful way, it is essential to be able to isolate the chimney, when the fire is not used, by a closing flap placed in the drain. The apparatus Fig. 3, board I / 2, includes the external air supply device adjustable by blower drawer, the heat-insulating jacket and the chimney closure flap 10 adjustable by a sector & ratchet 16, all assembled and adjusted by a solid frame which facilitates installation and connection to the flue. Le volet de fermeture 10 sert de réflecteur supplémentaire losqu'il est grand ouvert. The closing flap 10 serves as an additional reflector when it is wide open. 4 - Le profil de notre autre à rayonnement, qui permet de capter le maximum de chaleur d'un feu de bois à foyer ouvert, peut également être équipé pour chauffage mixte lorsque la cheminée est à construire. Fig. 4, planche 1/2. Dans ce modèle, la jaquette calorifuge eet supprimée. Le dispositif d'alimentation en air reste inchangé. La face arrière est alore aménagée pour réchauffer par convection l'air prélevé dans le local par des grilles 11 situées de part et d'autre de l'embrase de la cheminée et restitué après ré chauffage par deux bouches de chaleur de 250/150 mm, disposées sur les deux cotée de la hotte et raccordées par des tuyauteries flexibles de 150 mm de diamètre. 4 - The profile of our other radiation, which allows to capture the maximum heat from an open wood fire, can also be equipped for mixed heating when the chimney is to be built. Fig. 4, plate 1/2. In this model, the heat insulating jacket is removed. The air supply device remains unchanged. The rear face is alore fitted to heat by convection the air taken from the room by grids 11 located on either side of the base of the chimney and restored after reheating by two heat vents of 250/150 mm , arranged on both sides of the hood and connected by flexible pipes 150 mm in diameter. Le tout est assemblé avec une armature solide qui assure la fixation et l'ajustage du volet de réglage de cheminée et permet le raccordement rapide au conduit de fumée.The whole is assembled with a solid frame which ensures the fixing and adjustment of the chimney adjustment flap and allows quick connection to the flue. Dans ce modèle, le rayonnement est bien diminué, l'effet de chaleur est moins rapide mais vu les températures obtenues le rendement est excellent. In this model, the radiation is well reduced, the heat effect is slower, but given the temperatures obtained the efficiency is excellent. Tous ces dispositifs sont indépendant de l'habillage décoratif des cheminées. All these devices are independent of the decorative covering of the fireplaces. Dans les régions ventées ou dans le cas ou une ventilation mécanique met le local en dépression, la faible hauteur des maisons individuelles peut nécessiter l'aide d'un petit ventilateur pour rétablir une pression positive et permettre le tirage de la cheminée et le bon fonctionnement de la ventilation de la cuisine. In windy regions or in the event that mechanical ventilation lowers the room, the low height of individual houses may require the help of a small fan to restore positive pressure and allow the chimney draft and proper functioning ventilation of the kitchen. Ce petit ventilateur 13 de faible puissance à action centrifuge est prévu pour son installation dans la prise d'air. This small centrifugal fan 13 of low power is intended for its installation in the air intake. Combiné avec un léger réchauffage d'air 15, il évite de refroidir l'air du local après la combustion du bois avant la fermeture de la cheminée et de la prise d'air.  Combined with a slight heating of air 15, it avoids cooling the air in the room after the combustion of the wood before closing the chimney and the air intake.
