FR2505985A1 - Heat recuperator or fireplace boiler - has forced high temperature air flow heating central heating fluid - Google Patents

Abstract

The recuperator is placed in a fireplace hearth to take heat from the wood or coal fire. It has a cast decorative motif (W) in the base plate, so that the fire radiation and its visual aspect into the room into which it is installed is not spoiled. The recuperator has a top and a bottom collector, the latter being traversed by hot gases (H), the entry for the gas being at the hottest part of the fire, the heart of the hearth.

Description

la) - a) - The invention relates to a calorie recovery device, housed in a liter of an indoor fireplace, used to make a fire, for pleasure, or for cooking food.
b) - Operating principle: recovery of calories emitted by flames and hot embers
I - by licking of the bottom plate by the flames and circulation of very hot air, from the heart of the hearth, on the rear of the plate, by vacuum, the air entering from below, through the plate, and coming out from above; this effect can be improved by the installation of a mechanical, electric extractor.

 2 - Falling embers on the floor plate.

 3 - Position of the andirons in the brazier.

c) - Principle of recovery and restitution
By abso * tion of the calories emitted on the masses constituting the recovery device, and restitution on a water or oil circuit, or any thermal fluid, which can circulate in a central water heating.

The device is constructed in such a way that it performs better than any existing device, while retaining its decorative appearance thanks to
- to the circulation of very hot air, on
the plate career

On the side, as the case may be, at the rear of the plate, square irons will be fixed so as to receive a cover plate to form a box, part X, plate I and

 The number of rows of tubes is not limited to one, in the direction of thickness, but will be according to the powers that one wishes, and the possible power of the hearth, this remaining to our entire appreciation.

In the width direction, they will be arranged according to a pitch which will be adjusted according to the section of the tube chosen, and distributed over the length, see plate

 The inlet and outlet ports, A and B see on boards ggI, 1/2, 3 and 4 will be variable according to the flow and speed of the water which will circulate there.

 In some cases, depending on the height available, and depending on the plate models, the bottom air intake will be vertically, which will remove the opening on the front, in the lower part of the water box, part called K.

In this description, as we can understand, no rating can be given, given the multitude of applications that this invention will have, and which will be factor of the hearths or it will be arranged, 30) - Base plate
It will consist of a bundle, embedded by casting in copper, or aluminuim, see plate no bet 6.

 The beam will be made up of its thickness by one or more rows of tubes along its length, the arrangement will be given by a step, depending on the diameter. They will be welded at their ends to a base plate, a water box with threaded orifices will cover these bases, the whole will be judiciously embedded in the metal.

 This plate can be mounted, independently depending on the use that is desired of the rest of the elements.

The possibility of installation will come in addition to the bottom plate already described, or separately, depending on case 4) - Firebox support
- Molded case - this will be formed by a water collector made up of steel tubes, embedded ###### in a mass of cast metal, copper or aluminuiwi, with different stiffening and metal protection systems.

- Unmolded case - It will be made up of a special tube, it will include two collectors, one closed in the middle, the other making the extreme connection of the beam, see plate no
In the case of molding, even in principle, the quality of the irrigation tube will only change.

All of these elements can be mounted on a hearth plate forming a one-piece assembly see plate nQ 4ç
