International Convention - Priority of a patent application filed in France on March 18, 1980 under N * 80 05983.

"**" * "*" "" mmim ** · "* # · ** + ** # ** ** mm 1.- The invention relates to a heat recovery device with circulation of water for fireplaces.

It appeared necessary, because of the shortage of petroleum products, to actively seek to recover by any means a maximum of calories in order to save in return an equivalent mass of petroleum products.

Various devices have been recommended in particular as regards the recovery of calories from v so-called pleasure chimneys.

Thus, a multitude of recuperators have the aim, through a household circulator, of drawing fresh air to heat it in the circulator and then of returning it laden with calories in the living quarters by means of distribution outlets fitted for this purpose. on either side of the fireplace.

Such devices, although satisfactory on the whole, remain independent for example of a central heating installation and can in no case be connected with such installation.

However, it is on the contrary eminently interesting to relieve the functioning of the supply boilers of central heating installations (fuel, gas, electricity) by recovering as much as possible the calories emitted by the hearth of a chimney.

To this end, in a first known embodiment, a tubular device has implemented a set of horizontal and vertical L-shaped tubes, assembled at their ends by tubes for connection to an existing central heating installation.

H

The L-shaped tubes being single or double, that is to say two tubes slid into each other.

Such somewhat unsightly devices have major operating disadvantages due in particular to a progressive blockage of the tubes by fouling, hence a significant loss in the desired efficiency.

According to another known device, use was made of a grate of hearth forming an andir opening out onto a vertical box dressed with a hearth plate. The box 2.- being provided with means of connection to a traditional central heating installation. Here again, the desired efficiency has only been achieved in small proportions, having regard to the arrangement of the horizontal pipes forming chenet with respect to the box itself and to the heating coefficient of certain parts of the hearth of the chimney.

In another known variant, use has been made of a vertical hollow cast iron plate fitted with horizontal pipes, such a device. However, 1Q has the major drawback of having points 5 which are particularly vulnerable to strong expansion due to temperature changes in the hearth, hence untimely leaks which are particularly troublesome for any central heating installation.

In other devices, use has also been made of two boxes connected one horizontally and 1 * vertically or else to a tubular circuit embedded in a chimney plate made of cast aluminum, but these devices like those previously described generally have given only a small percentage of recovery while presenting a set of major drawbacks which therefore do not allow reliable and safe use.

The object of the invention is to remedy these drawbacks and to this end relates to a device for recovering calories from water circulation for fireplaces with perfect aesthetics, safe, efficient operation and a price. relatively interesting cost allowing, thanks to the new combination of means used, a large and rapid recovery of calories produced by the hearth of a chimney and a return of these calories in a very short period of time at installation itself central heating.

In addition, this particularly compact and reduced device easily adapts to all fireplaces without any particular adaptation or modification.

To this end, the invention relates to a device for recovering calories with water circulation for chimneys, characterized by a circuit produced by an assembly of tubes, arranged in parallel and connected to each other to form a single circuit having a profile in shape. L, ^ 0 embedded in a mass of a highly heat-transferable material, the * '3®- vertical part of the device being provided on the vertical front face with a traditional bottom hearth plate and the horizontal flat part being provided with or not * another hearth plate.

5 The invention, without limitation, is described in the accompanying drawings in which: - Figure 1 shows schematically in rear view of 3/4 the device according to the invention, - Figure 2 is a sectional view 10 of side of said device, t - Figure 3 is a front view of the device, - Figure 4 shows 1 * ashtray element.

1 ^ According to a first characteristic of the invention as shown in FIGS. 1, 2 and 3 "the device 1 for recovering calories with circulation of water for chimneys comprises a circuit 2 produced by an assembly of tubes, arranged in parallel and connected to each other to the others to form 20 u · 11 single circuit having an L-shaped profile embedded in a mass 3 of a highly heat-transfer material ^ the vertical part 4 of the device is provided on its vertical front face with a hearth plate 5 of traditional cast iron and the horizontal flat part 6 is provided or not with another hearth plate 7® 2 ^ According to another characteristic of the invention, the circuit 2 as shown in FIG. 2, in the shape of an L is preferably made of tube of refrigerating type copper in an appropriate diameter and comprises in its horizontal part as well as in its vertical part means of connection 8 and 9 to an existing central heating installation.

'According to another characteristic of the invention, as shown in Figure 2, the rear horizontal and vertical part 6 4 of the device 1 is provided with an insulation means 10 such as glass wool or rock wool intended to preserve to the heat transfer mass all the calories recovered.

According to another characteristic of the invention, the mass 3 of the heat-transfer material can be produced by means of a metal alloy, refractory cement, chemical product or the like with or without a box, or the like having a capacity for heat absorption. high resistant to contact temperatures above 250 ° C without melting or decomposing.

5 According to a new characteristic of the invention, the mass 3 of the heat-transfer material is produced by a composition which comprises the main constituents below: alumina in a proportion of 1 * of the order of 40 ° / o 1 o silica in a proportion of 1 * order of 37 ° /> »calcium mixture in a proportion of 1 * order of 18 ° / o.

The purpose of this highly heat-transferable material is to transfer a maximum of the calories emitted by the wood fire and absorbed into the tubular circuit embedded in its mass. by the vertical and horizontal hearth plates. It allows these plates to be kept at a very high temperature in order to achieve perfect combustion, thus eliminating the risk of gumming on the surfaces, which would reduce the yield of the process.

The heat recovery coefficient 20 represents approximately 80 ° Jo of the calories usually absorbed by the chimney with the fumes and which do not benefit the heating of the house.

The tubular exchanger forming circuit 2 quickly reaches a temperature of more than 100 ° G, which makes it possible to very quickly heat up the central heating installation fitted with this device.

According to another characteristic of the invention, the device 1 recovering calories, receives on its vertical front face 4 a plate of traditional hearth cast iron 5 "in addition, the whole of the device to a thickness of the order of 5 cm > which does not compromise the depth of the hearth and which allows easy installation without particular modification or adaptation.

The hearth plate 5 is fixed to the vertical heat transfer mass 3 and the thermal bridge can be provided by a preferably metallic binder.

According to another characteristic, as shown in FIG. 4, the horizontal part 6 of the device 1 receives a sheet of steel forming a hearth plate and an ashtray 40, fitted with two carrying handles 12 allowing on the one hand to dress aesthetically the horizontal part 6 of 5.- device 1 and on the other hand to easily and effectively empty the hearth of its ashes.

According to a last characteristic of the invention, the device 1 for recovering calories can be adapted to any traditional central heating installation but also to solar collectors and heat pumps, and can be used as complete heating in temperate regions. or secondary residences but also as additional heating in other cases while allowing significant energy savings.

* The invention generally applies to heating and energy savings.
