FR2523273A1 - Energy recuperator for fireplace hearth - has heat entering sides plus base and rear to heat water - Google Patents

Abstract

The recuperator has lateral sides (3,4) and a guide (10) on the back wall (2) to take a stand that uses only a single foot to rest on the base (1). The stand eases the passage of a scraper freeing it from ashes without lifting or displacing the stand. The return water from the radiators enters the internal front part of the recuperator, the latter taking any type of embellishing accessory.

Description

The present invention relates to devices of the "Energy Saver" type, inside which water circulates, enabling the energy from the wood fire from the hearth of a fireplace to be transmitted, to the water radiators. heating season 3
In known devices of this kind, the recovery is done under the che che nets on the ground and on the part of the bottom of the chimney, which lets out part d. heat from the sides.

 The recuperator according to the invention makes it possible to retain the energy, lost on the sides, due to the fact that by its shape the water also circulates on the sides of the apparatus, which makes it possible to have a space requirement in interior height for the same efficiency and superior cleaning efficiency for a height equal to known recuperators.

 The accompanying drawings are views representing the description below with numbered markers.

 As numbered and shown, the Energy recovery unit includes: two boxes 9 four sides 10 The 801 2 The vertical bottom 30 Right side 4 The left side, which boxes are nested one inside the other.

The inner box on which the chenets are placed, being smaller than the outside box just the space that we want to leave for the water circuit
These boxes are sealed by a flat iron border 5. or the edge of the sheet, of one of the folded boxes.

 For safety measure against pressure resistance, there are provided between the two boxes, round reinforcements, profiles etc ;;; which serve as spacers 6.

 In the upper part there is a sleeve 7 for the flow of water to the radiators and a second sleeve 8 for the return of water from the radiators to the recuperator.

 The part of the sleeve 8 which is towards the inside of the recuperator is extended by a tube or the like 9 which delivers the water from the return towards the front of the device.

 These sleeves are placed diagonally opposite one another but can be placed in a different longitudinal direction, it being understood that one 7 will be at the highest part and that the other 8 will be at the most lower with always the tube or other 9 of the return which will open inside the Recuperator always diagonally v @@ the front with respect to the sleeve 7 starting from the radiators.

A slide 10 fora body with the vertical bottom 2, it will be able to receive the special chenets it comprising: a very short foot which will take appni on the slide and a second vertical foot, whose extremity ends in a flat cross giving it stability;
The interest of the chenets in a single point of support on the floor 1 of the Recuperator is that it will facilitate the passage of a squeegee for the décendrago.

 The description above is that of the steel recuperator, but its manufacture could be designed with other metals, or rolled out, such as cast iron, aluminum, etc .; the form and operation remain the same.

 The initial presentation is simple, its lines are sober, so all decoration accessories, such as wrought iron, copper, brass, stainless steel or others, can be added as well as possibly external insulation.

 This recuperator by its shape can in some cases improve the draft of the chimney.

 This assembly can be connected to an existing central heating system or mounted alone to supply radiators.

 It can also be mounted on a sanitary water heating connection.
