Definitions

  • the invention relates to a tiled stove insert, the heating box of which has an impermeable intermediate floor located under the combustion chamber, a flue gas chamber on the floor side and an impermeable intermediate wall which is arranged at a distance adjacent to the rear wall of the heating box and delimits a rear flue gas chamber and ends at a distance from the top wall of the heating box
  • Both flue gas chambers communicate with each other, the flue gas chamber on the bottom is closed by an openable front shut-off plate and a flue gas outlet connection is connected to the flue gas chamber on the rear side, and the flue gases in the flue gas chambers are in heat exchange with ambient air.
  • Such a tiled stove insert is known from US-A-4,397,293.
  • two lateral intermediate walls are also provided.
  • the combustion chamber is thus surrounded by a flue gas chamber on the bottom, a flue gas chamber on the rear and two flue gas chambers on the side.
  • the intermediate floor does not delimit the combustion chamber or the ash pan at the bottom, it is rather between the grate and the heater box floor and is formed by an air duct box.
  • the flue gases flow through the grate down into the bottom flue gas chamber and from there in the three vertical flue gas chambers up to the outlet nozzle.
  • GB-A-1,176,944 shows another tiled stove insert in which an intermediate floor is missing.
  • a rear partition divides a rear flue gas duct, which communicates with the combustion chamber on the bottom and leads to the outlet nozzle.
  • the partition is hollow. Combustion air is blown into the intermediate wall for preheating by means of a fan and exits through outlet openings both into the combustion chamber and into the flue gas duct.
  • the object of the invention is to improve the use of the tiled stove of the type mentioned with regard to the heating power and the easy and better cleaning possibility.
  • the intermediate floor connects directly to the front wall of the heating box and separates the combustion chamber from the floor-side flue gas chamber in a flow-tight manner that both flue gas chambers are divided into partial chambers by vertical partition walls that the at least a partition located below the intermediate floor at a distance from the front wall ends between the upper edge of the intermediate wall and the top wall in the area of at least a first vertical subchamber, a flue gas inlet opening communicating with the combustion chamber is formed for the subchamber that connects to the upper edge of the intermediate wall in the Area of the adjoining second partition separated by the partition connects a connecting wall leading to the top wall and the flue gas outlet connection is assigned to this second partition and that each rear part came with a bottom part communicated and the flue gases are guided in countercurrent in neighboring subchambers.
  • the invention can be used in furnaces with or without a grate. If there is a grate in the combustion chamber, the intermediate floor is still below the floor of the ash collecting chamber.
  • the bottom flue gas chamber is closed by its own front shut-off plate, which creates a very good cleaning option after removal. In the case of kiln grates, the ash pan can be pulled out without problems, which is not possible in the prior art mentioned at the beginning because of the air inlet pipe provided there.
  • the subdivision of the flue gas chambers into sub-chambers enables the flue gases to be extracted in the upper area of the combustion chamber.
  • the flue gases then flow downwards in a first subchamber behind the partition, are then guided forward in a bottom subchamber, then deflected by 180 ° in the adjacent bottom subchamber backwards and then through a rear wall subchamber up to the outlet port.
  • the upper inlet opening of the rear-side partial chamber allows easy cleaning of this rear-side partial chamber. Since the connecting wall of the adjacent subchamber can be made foldable or removable, this subchamber can also be cleaned from above. Since at least four subchambers are connected in series on the flue gas side, the heat transfer and thus the heating output are increased due to better flow conditions.
  • At least the rear-side partial chambers are preferably arranged at a distance from one another and each delimited by a separate partition, so that air can also circulate between the partial chambers, which further increases the heating power.
  • One embodiment consists in that the two flue gas chambers are each divided into three sub-chambers by two partitions or pairs of partitions, that the two outer rear part chambers have upper flue gas inlet openings and the flue gas outlet nozzle is assigned to the intermediate part chamber.
  • an air supply opening that can be shut off at the front opens into a transverse channel extending into the opposite side walls, the two ends of which are each connected to a horizontal side channel which extends at least to about the front half of the combustion chamber and is provided with a number of air outlet openings such that a chamotte bottom pan connects the combustion chamber bounded below and that the two side channels are arranged directly above the upper side edges of the floor pan, with an air duct or air outlet opening facing the combustion chamber, which communicates with the air supply opening and extends over substantially the entire width of the combustion chamber, directly above the front upper edge of the floor pan is provided.
  • the front air outlet opening is preferably formed by a continuous slot which extends almost over the entire width of the furnace, the air channel communicating with the transverse channel on both sides of the combustion chamber door. All air outlet openings are preferably at the same height. Fresh air is therefore supplied to the combustion chamber from three sides, which ensures uniform combustion, which in turn has a favorable effect on the heating output.
  • an impermeable floor pan delimiting the combustion chamber at the bottom is arranged at a distance above the intermediate floor, that an air preheating duct heated on both sides is formed between this and the intermediate floor, which connects to the transverse duct and extends to a rear wall duct between the intermediate wall and the flue gas chamber on the rear wall and is provided with air outlet openings in the area of the intermediate wall.
  • One embodiment consists in the fact that the bottom-side smoke gas chamber and the rear-side smoke gas chamber communicate with one another via an oblique connecting chamber.
  • This connecting chamber thus runs from the bottom flue gas chamber at an angle of approximately 45 ° upwards to the flue gas chamber on the rear wall.
  • the air outlet openings are preferably set back in relation to the fireclay walls arranged directly above them. So they are protected against deposits and cannot be blocked.
  • At least one further duct is arranged at a distance above the side ducts and / or the rear wall duct, is provided with air outlet openings and is either connected to the transverse duct and / or the preheating duct or is connected to its own secondary air supply system, which has an inlet opening which can be controlled independently of the supply opening for primary air.
  • fresh air can be supplied on all four sides in the floor area of the combustion chamber and also on at least three sides in an upper area.
  • the air supply to the primary system at the bottom can then be controlled independently of that into the upper secondary system.
  • the primary air supply opening is immediately adjacent to the secondary air inlet opening. This makes it possible to use a slide for primary air and to provide a controllable opening for the secondary air in the slide.
  • the inlet opening for the secondary air is preferably located under the inlet opening for primary air.
  • the combustion chamber 12 of a tiled stove insert 10 is delimited by a front wall 14 with a stove door 16, a floor pan 18, a rear wall-side intermediate wall 20, a cover wall-side intermediate wall 22 and side wall plates 24, which consist of chamotte or have chamotte linings.
  • the flue gases leave the combustion chamber 12 through the opening formed between the front wall 14 and the intermediate wall 22 on the top side, then flow backwards into a flue gas flue 26 on the top side and through inlet openings 33 into two lateral subchambers 30a behind the intermediate wall 20, then into two, via channels one oblique connection box 37 adjoining lateral bottom-side subchambers 28a to the front, are then deflected in each case by 180 ° and flow backwards in a middle bottom-side subchamber 28b and through an oblique connecting channel upwards into the middle subchamber 30b, which is between the two outer subchambers 30a is formed, upwards to the flue gas outlet connection 32.
  • the bottom partial chambers 28a, 28b are each separated by a vertical partition wall, which ends at a distance in front of the front wall 14. In the same way, the back could wall-side subchambers 30a, 30b.
  • the drawing illustrates a superior design according to which a partition wall pair is arranged at a distance between two partial chambers 30a, 30b, so that air can circulate between the two partition walls 27. These partitions are ribbed on the outside to increase the heat transfer to the ambient air.
  • the subchambers 28a, 28b are closed at the top by an impermeable, continuous intermediate floor 23 and can be cleaned from the front by a removable front shut-off plate 31.
  • the middle rear partial chamber 30b is closed off from the top flue gas flue 26 by means of a connecting wall 35, which is designed as a flap and can be actuated from the outside in order to direct the flue gases directly into the outlet connection 32 when the furnace is heated.
  • the hinged connecting wall 35 also serves to clean the middle rear partial chamber 30b, since the cover wall-side intermediate wall 22, which only rests on shoulders of the side walls 24, can be removed, after which this middle partial chamber 30b is accessible from above when the connecting wall 35 is open .
  • the transverse channel 38 Adjacent to this covered area, the transverse channel 38, which extends over the entire width of the front wall 14, communicates with a transverse outlet channel 40 which is delimited in the area of the door by a horizontal wall 42 of the door 16 at the top.
  • this outlet channel 40 has a front-side outlet slot 44 that extends over the entire width of the combustion chamber 12.
  • the transverse channel 38 communicates with riser channels, to which side channels 46 connect, which are provided with outlet openings 48, which are approximately the same Level as the front exit slot 44 are located.
  • the side channels 46 are cast iron moldings which are placed on the side edges of the floor pan 18.
  • the chamotte side walls 24 extend down to the upper edges of the side channels 46.
  • a preheating channel 50 is formed between the floor pan 18 and the intermediate floor 23 delimiting the floor-side partial chambers 28a, 28b, which connects to the cross channel 38 and extends over the entire length of the furnace, is designed to rise obliquely in the rear area and opens into a rear wall channel 52, which corresponds in cross section to the side channels 46 and also has outlet openings 54.
  • the rear wall channel 52 extends over the entire width of the intermediate wall 20 and also lies on the rear raised edge of the floor pan 18 and is therefore at the same height as the side channels 46.
  • the execution according to FIG. 4 is only shown schematically for better understanding.
  • the fireclay liners and the flue gas system were omitted.
  • the tiled stove insert 11 according to FIG. 4 also opens the air supply opening 36 in the transverse channel 38, which communicates with the two side channels 46.
  • the space between the schematically illustrated floor pan 18 and the intermediate floor 60, which delimits the partial chambers at the top, is divided into three chambers by vertical, longitudinal dividing walls 62, 64, of which the two outer chambers form the preheating channels 50, which are directly connected to the transverse channel 38 are and open into a back wall chamber 66 extending over the entire width of the tiled stove insert 11, which back wall channel 52 in the embodiment according to FIG. 1 corresponds and has the outlet openings 54.
  • a further middle preheating duct 68 which is connected at the front to a chute 70 within the transverse duct 38 and is fed into the fresh air through an inlet opening 72, which is arranged directly below the supply opening 36 and can be controlled by means of a separate slide is.
  • the inlet opening 72 supplies secondary air to the combustion chamber, which flows through the central preheating duct 68 into a riser chamber 74, which has approximately half the depth of the rear wall chamber 66 and leads upwards therein and in an opening 78 of an end wall 76 which closes the rear wall chamber 66 at the top flows. Above this end wall 76 there is an upper rear wall chamber 80 of less depth than the lower rear wall chamber 66.
