Definitions
- the present invention relates to a fireplace closed combustion improved including wood and increased temperature.
- It also relates to improved primary and secondary air supply circuits and thermal insulation and thermal inertia in the case of a closed fireplace including wood with at least one transparent wall of flame vision.
- the main purpose of the invention is to substantially increase the operating temperature of the furnace while keeping it as long as possible in order to obtain a better combustion, a pyrolytic elimination of the maximum of 1 unburned and of products staining the interior of the furnace. fireplace, especially the inside of the glass door.
- Another object of the invention is to increase the speed of the outlet airflow, thus removing more quickly and more volatile materials which may dirty the inside of the hearth and the rear face of the glazed door.
- the invention also aims to provide an improved primary and secondary air supply circuit for a closed fireplace contributing fireplace better combustion and cleanliness of the fireplace.
- the inventors have designed a side system for supplying primary combustion air, passing through each time a refractory block and opening by means of orifices located on each side of the hearth approximately level with the fire.
- the invention also relates to a secondary air circuit which starts from the air inlet and extends upwards along the bottom and side refractory blocks to give rise to a heated air flow which is projected. in a descending layer against the rear face of the glass wall of the chimney door to ensure cleanliness, on the one hand by removing the dirty particles by the force of the air flow, and on the other hand by burning those arriving nearby by the high temperature of the air flow and its oxygen richness.
- Figure 1 is a general perspective view of a closed fireplace according to the invention.
- FIG. 2 is a general perspective view of the front of a closed hearth chimney according to the invention, the lateral part of the body of the chimney being shown partially cut away and transparent for the thermal insulation plate and the cladding of the sidewall, the air flows being represented by arrows;
- Figure 3 is a general perspective view, similar to that of Figure 2, of the front of a closed fireplace according to the invention, wherein the upper part of the door and its frame was also partially removed;
- FIG. 4 is a general perspective view of the rear of a closed hearth chimney according to the invention, the rear and side portion of the body of the chimney being partially shown in cutaway and transparent for the thermal insulation plate; and the dressing of the side and the back; .
- Figure 5 is a schematic sectional view taken horizontally through the fireplace of a closed fireplace according to the invention.
- a primary air and secondary air circuit designed to improve combustion and to ensure the cleanliness of the glass regardless of the appearance of the fire.
- a solid-fuel burning appliance in particular with wood, for example a closed hearth with a metal body 1 taken by way of example, with a front door 2 having a curved or multifaceted glass surface 3, and an interior fireplace 4, a total interior lining is provided, but at least lateral to the hearth and bottom of hearth in the form of refractory blocks.
- lateral blocks 5 and 6 and base blocks including a central block 7 bottomed bottom 8 and peripheral blocks such as 9 and a special front block 10 shaped fender 11 constituting the front stop for the logs of wood .
- the refractory blocks have a density and a thickness adapted to act as a heat accumulator having an effective thermal inertia to ensure a certain thermal relay between the different heating stages.
- thermal insulating plates 12 and 13 of sufficient thickness dress the inside or outside face of at least each of the side walls of the hearth body and it is possible to optionally provide a cast iron plate that occupies at least a portion of the rear wall of the fireplace. This cast iron plate acts as a steering wheel additional thermal acting in conjunction with the refractory blocks.
- thermal insulation of the hearth Various other means of thermal insulation of the hearth are possible such as sandwich structures, hollow structures in which heated air passes or other.
- the general purpose is to limit thermal losses by radiation from the walls of the body of the home.
- thermoly insulating glass single or double glazed glass can be used for the glass door.
- the fireplace comprises a circuit 14 for supplying primary and secondary air.
- This circuit has a single input 15 at the rear of the apparatus formed of a junction box 16 to an air intake duct, the box covering an air intake opening 17 with an adjustable flow rate, for example under the shape of a pivoting flap 18 controlled by a handle or an operating lever 19 outside the device connected by linkage to the pivoting flap 18.
- the air inlet opening 17 is located approximately in the middle position at the rear of the hearth. It opens onto a channel 20 along the rear of the hearth which forms two branches 21 and 22 each going to one of the rear corners 23 and 24 of the hearth 4.
- the airflow is divided on each side of the hearth into two branches: a branch of secondary air 25 and 26 along the vertical rear edge of the hearth and a horizontal branch of primary air 27 and 28 respectively following each lateral side of the fireplace under the corresponding lateral refractory block.
- the secondary air circuit is formed of two symmetrical parts joining in the upper part of the glass wall.
- Each lateral refractory block 5, 6 has a parallelepipedal overall shape with an oblique cutaway 29 and 30 with a rear edge each forming, when the lateral block is in place, with the dressed side wall of the thermal insulation plate 12 or 13 and the back plate of the hearth body, the two joining at the rear edge, a rising channel 31 or 32 of triangular section forming each rising branch 25 or 26 along which the secondary air travels to the upper part of the hearth .
- the secondary air path continues forward on each side by an upper transverse channel such as 33 running along the top of each refractory block transversely and at the edge of the hearth.
- the upper transverse channels 33 extending each ascending branch 25 or 26 of the secondary air circuit open at the ends of a distributor 34 whose shape follows at a distance the contour of the upper part 35 of the glass part 3 to create at this level a descending air curtain preferably guided by means of a curvilinear baffle 36 inclined downwards ( Figure 3).
- This air curtain provides a hot air flow in a down ply to ensure the cleanliness of the glass by removing the messy particles that could stick on the rear face of the glass and burning those of them.
- the primary air arrives at the rear of the side refractory blocks 5 and 6 after preheating the along the edge of the base of the hearth itself filled with refractory blocks 7 and 9.
- a group 37 orifices such as primary air inlet furnace gui individually communicate with outlet openings of the side channel by recesses such as 39 dug in the rear face of each side block 5 and 6. The primary air is thus still heated in contact with each refractory block before leaving it in the firebox.
- the air circuits described above by the location of their outlets and the reheating of the air they allow, contribute to ensure perfect cleanliness of the rear face of the glass wall of the chimney and excellent combustion of solid fuel, for example wood, which provides energy saving and reduced emission of pollutants.
- solid fuel for example wood
