Definitions
- the invention relates to an oven with a combustion chamber, in particular for tiled or storage fireplace.
- Tile and storage fireplaces are enjoying increasing popularity. They are often used as additional heating so that the central heating does not have to be switched on or no longer needs to be switched on during the transition period, thus saving energy. Furthermore, furnace heat is felt more comfortable. In both the tiled stove and the storage stove, the heat is released into the room mainly through radiant heat as well as convection heat.
- the basic furnace is mainly made of ceramic materials (chamotte), which can store the heat. Thick-walled materials generally cause a relatively long heating-up time and storage capacity at a low surface temperature.
- the design principle of the ovens is essentially the same.
- the invention has for its object to provide a furnace with a combustion chamber, the arrangement of flue gas or. Convection channels on the side walls while using the entire width of the oven for the front width of the firebox or the width of the door as well as the simple construction of insulating plates.
- the cross section of the firebox is essentially triangular, so that the entire furnace width minus the wall thickness of the side walls is available as a width for the firebox or the door on the front or door side. Fuel can thus be supplied to the combustion chamber much more easily.
- the combustion chamber tapers towards the rear accordingly, whereby a flue gas or convection duct is formed between the side walls of the furnace and the rear firebricks on the combustion chamber. This makes it possible to guide the flue gas or convection duct for the exhaust air in a ring around the combustion chamber, even though the entire furnace width minus the side walls comprises the combustion chamber opening at the front.
- the exhaust gas flow is preferably guided in such a way that a back-firebrick is made shorter than the height of the combustion chamber, which results in an inflow opening via an overlying, in particular inclined, deflection plate.
- the exhaust gases flow downward into an intermediate space below the combustion chamber and then through the second convection channel into an intermediate space with deflection firebricks above the combustion chamber. From there, the exhaust gases enter the chimney pipe through an opening.
- the heat is optimally extracted from the flue gas flow to increase the efficiency of the furnace, and at the same time the firebricks of the furnace are evenly heated all around.
- Figure 1 is a perspective view of a storage fireplace open on the front without a tiled casing.
- Fig. 2 shows a cross section through a combustion chamber of the
- Fig. 3 is a perspective view of a storage fireplace closed on the front.
- FIG. 1 the perspective view of the core of a storage stove 1 is shown with an open front. This has legs 14 and an insulating plate 5 on the bottom.
- the side walls 2 are delimited at the top by a cover firebrick 6 with a chimney pipe opening 15a, lie on a base plate 16 or intermediate plate 17 and are thereby interrupted by an intermediate plate 17. Furthermore, there is a chimney pipe opening 15b in the firewall rear wall 11.
- the combustion chamber 23 is formed, which is delimited at the rear by rear-fired bricks 3a, 3b, which preferably carry a vermiculite layer towards the combustion chamber 23, as is also provided for the combustion chamber floor 9 in the manner of a sandwich construction is.
- the back firebricks 3a, 3b can also be somewhat curved or rounded.
- the exhaust air or flue gas flow in the flue gas duct is shown in dashed lines. Starting from the upper deflection or inflow opening, which can also be delimited by an inclined deflection plate 3c, it moves down along the shorter left rear firebrick 3a to the space 24b between the intermediate element 18 and the Base plate 16. With the aid of deflection firebricks 4, the flue gas flow is deflected here and rises in the convection channel 10 behind the rear firebrick 3b into the upper intermediate space 24a between the cover firebrick 6 and the intermediate plate 17. A deflection firebrick 4 is also arranged here. The flue gas stream escapes through chimney openings 15a or 15b (depending on the existing chimney connection) into the chimney pipe (not shown).
- the intake air 22 (primary, secondary and purge air) flowing between the insulation 5 and the base plate 16 is deflected on the underside of the storage stove 1 by deflection plates 7 and thus preheated.
- the primary air is introduced into the combustion chamber 23 on the furnace door 19 on the combustion chamber floor 9 (FIG. 3).
- the secondary air is sucked in with the aid of a pipe 8 arranged on the floor and flows out of the slotted or perforated sheet metal duct 20 into the combustion chamber 23 on the rear side of the combustion chamber 23.
- the sheet metal channel 20 is fastened to the cut edge between the two rear firebricks 3a and 3b or the vermiculite layer applied thereon, so that a rectangular flow tube results.
- the preheated purging air flows in the side rail spars (not shown) first upwards and then downwards from the top of the oven door 19 in order to keep the window of the oven door 19 free of soot or clean (FIG. 3).
- the storage fireplace 1 shows a cross section through the storage stove 1 approximately in the middle of the height of the combustion chamber 23.
- the entire furnace 1 is surrounded by a ceramic storage sleeve 21, possibly with insulating plates 5.
- the storage fireplace 1 consists on the sides of a fireclay rear wall 11, a fireclay front wall 13 and fireclay side walls 2, which are shown in dotted lines.
- the furnace core or interior is subdivided by two dotted rear-fired bricks 3a, 3b, which preferably have a vermiculite layer (drawn more narrowly dotted) towards the combustion chamber 23 in order to improve the burnout behavior and the efficiency of the furnace.
- the front thus forms the combustion chamber 23, while on the rear the two flue gas or convection channels 10 for the exhaust air or here a lintel and on the right a climb for the flue gas are formed.
- the intake pipe 8 for the secondary air 8 is integrated, and underneath in the room 24b is the transverse train connecting the fall train with the riser train (channels 10).
- the sheet metal duct 20 is fastened in the corner region between the two rear firebricks 3a, 3b, so that secondary air can escape into the combustion chamber 23 from slots or holes in the sheet metal duct 20.
- this flow tube is covered by a triangular part 22 of the sheet metal channel 20, as a result of which the deflection plate 3c can be additionally supported.
- the mutual locking of the plate elements 2, 13, 3a, 3b, 3c etc. takes place by simple plug connections.
- the storage fireplace 1 can also be assembled in-house by the end user. To facilitate this, the individual elements can be easily assembled using tongue and groove connections or knobs 25.
- FIG. 3 shows the perspective view of a completed core of a storage stove 1.
- the storage stove 1 is delimited at the top by a covering brick 6, under which the upper transverse or reversing train for the flue gas rising from the rising train (in the right channel 10 here) is formed.
- the intermediate plate 17, the intermediate floor 18 and the base plate 16 lie in a vertical subdivision. Access to the combustion chamber 23 takes place on the fireclay front wall 13 via the furnace door 19.
- the fireclay side walls 2 form the end on the right side of the core of the storage stove 1.
- the storage stove 1 stands on the legs 14, between which the insulating plate 5 is located.
- the deflection plate 7 is used for better preheating of the intake air 22 (primary, secondary and purge air).
- the dashed line shows the path of the exhaust air or exhaust gases.
- the three arrows indicate three different connection options for a chimney pipe, whereby a mirror-image connection is also possible.
