Definitions

  • the present invention relates generally to a piping system for a heater, and more particularly to a piping system for conducting secondary air to a heater such as a furnace.
  • heaters in which combustibles can be burned, known, such as tiled stoves, stoves, pellet stoves and central heating systems, which may also be partially mixed forms of the aforementioned ovens.
  • Modern stoves which are also placed in the living room, for example, often need a fresh air connection, since, for example, low-energy houses are built so tight that fresh air through leaky windows, or similar. no longer get into the living room. Therefore, the consumption of oxygen from a kiln in the living space would lead to an unwanted reduction in the indoor air oxygen content.
  • the aesthetic aspect plays a major role. It is desirable that a fresh air supply port can be made to the oven that does not disturb the overall aesthetic impression. Therefore, it is desirable to place the kiln appropriately close to the wall without pipes being visible through the supply air and exhaust gas.
  • the object of the present invention is to provide an improved piping system.
  • the present invention provides a combustion furnace for combustion of a fuel comprising: a combustion chamber and a conduit system, the conduit system directing air at least partially through the combustion chamber from a lower portion of the furnace into an upper portion of the furnace.
  • FIG. 1 an embodiment of a piping system in accordance with the present invention is illustrated.
  • ovens or furnaces which use wood as fuel, for example, in various embodiments.
  • the kilns differ in their purpose.
  • kilns have the sole purpose of generating heat in a living space, or serve only as a nice eye-catcher.
  • other furnaces additionally include, for example, a baking compartment and some even serve as central heating.
  • any mixed forms are realized again.
  • a stoves which includes a transparent panel on its front and thus serves as an eye-catcher in a living room and is also still water leading to serve as a central heating and possibly even used pellets as fuel, so that the fuel supply can run largely automated.
  • biomass burning means used such as wood in the form of logs, wood waste, which are pressed into pellets, for example, but also wood briquettes, coarse chippings, finely chopped, shredded or Halmgutpellets.
  • an important factor is the air supply.
  • air is taken from the room air surrounding a kiln.
  • the air supplied comes from an unfinished space, for example, from outside a house, that is, from the "outdoors".
  • the air supply is divided into a primary air and a secondary air.
  • the primary air is directed from below to the combustion site, while the secondary air is introduced from above to the combustion.
  • This division into primary and secondary air is realized in various ways.
  • there is a central supply air supply for example by an externally supplied fresh air line. This fresh air supplied from the outside is then subdivided, for example, by a corresponding supply air control device into primary air and secondary air.
  • the kiln includes a piping system through which the (fresh) air is passed accordingly.
  • fresh air is introduced through a central connecting pipe from the rear into a lower region through a corresponding supply air connection to the kiln. Then it is subdivided into primary and secondary air in the supply air control device and accordingly continued by a primary air and secondary air piping.
  • the secondary air is at least partially directed through the combustion chamber of the kiln from the lower portion of the kiln to an upper portion. By guiding the air through the combustion chamber, the air is heated accordingly.
  • a compact design of the kiln is made possible by the leadership of the ducting system through the combustion chamber.
  • the kiln also includes, for example, a transparent panel, for example, mounted in an oven door.
  • Clear windows in furnaces tend to fog and so that in some embodiments the secondary air is directed from the top of the combustion chamber into the lower area of the combustion chamber along the clearing disc, such as a kind of air curtain, causing fouling and / or fogging of the pane is prevented.
  • the secondary air falls due to their lower temperature and the associated higher density than that of the combustion chamber located in the combustion chamber air from top to bottom. In the lower region of the combustion chamber, the secondary air is then supplied to the combustion, for example.
  • the secondary air is cooled by a heat exchanger located in the kiln.
  • a heat exchanger located in the kiln. This is particularly advantageous if the temperature difference between the secondary air and the combustion chamber air is insufficient, that the secondary air drops to the extent that it is kept clean to the extent.
  • the heat exchanger is in some embodiments in connection with the ambient air surrounding the kiln, so that heat of the secondary air is discharged to the room air and thus the kiln surrounding space is heated not only by heat radiation emitted by the kiln, but also by preheated air.
  • FIG. 1 illustrates a first embodiment with a kiln 1 and a piping system 3 in accordance with the present invention.
  • the kiln 1 comprises a combustion chamber 7 in which, for example, fuel is to be burned.
  • the supply air control device 15 has a supply air connection 12 through which supply air 11 can be supplied.
  • the supply air 11 can be taken from the ambient air surrounding the kiln 1, or else independently thereof, from the outside, for example as a fresh air supply from outside a building.
  • the supply air control device 15 has a primary air opening 19 and a secondary air opening 17, is distributed by the supplied supply air 11 into the combustion chamber 7. As can be seen from Fig.
  • supply air 11 which flows out of the secondary air opening 17, through a corresponding secondary air duct 3, the center in a rear portion (left in Fig. 1) of the kiln 1 is arranged, passed to the combustion chamber 7 upwards.
  • the secondary air channel 3 extends in its extension 13 in an oblique direction in an upper region of the combustion chamber 7 and finally ends in a distribution chamber 21, in which the secondary air from the secondary air duct 3 is distributed so that it as an air curtain on the entire width of a transparent panel.
  • the transparent panel 87 is flushed as it is and fogging and sooting is prevented.
  • the secondary air enters a lower region of the combustion chamber 7 in order to supply combustion there with appropriate air.
  • the secondary air channel 3 is therefore passed through the combustion chamber 7 in its upper section 13. In this section, we heat the secondary air even further.
  • the proportion of the piping system 3 which is guided through the combustion chamber 7 varies in the exemplary embodiments. In this embodiment, essentially only the upper part 13 of the ducting system 3 is guided through the combustion chamber 7. In other embodiments, for example, the lower part of the piping system is guided through the combustion chamber. In still others, however, only a smaller portion of the piping system, for example only part of the section 13 shown in Fig. 1, passed through the combustion chamber.
  • a second embodiment is illustrated with a kiln 51 having a ducting system 53 in accordance with the present invention.
  • the kiln 51 comprises a supply air control device 65 which distributes supply air 61 (supplied from the left in FIG. 1) through a primary air opening 69 and secondary air opening 67 into a combustion chamber 57 of the kiln 51.
  • the supply air control device 65 includes a supply air connection piece 62 and can automatically by an electric motor drive or also be controlled manually.
  • the secondary air exiting the secondary air opening 69 is directed upwardly through a secondary air duct 53 which is centrally located behind (left in FIG. 1) the combustion chamber 57, i. in an upper region of the combustion chamber 57.
  • the secondary air duct 53 bends in its section 63 to the right in FIG. 1 and is surrounded by a heat exchanger 66.
  • the secondary air ascends in the secondary air duct 53, the secondary air is heated by the heat radiated from the combustion chamber 57, so that the secondary air would no longer fall down as desired in the subsequent rinsing process via a transparent pane 55. Therefore, by the heat exchanger 66, which communicates with room air, for example, which surrounds the kiln 51, the secondary air heat extracted and discharged to the room air, so that due to the cooling of the secondary air has a sufficiently high density to the function of purging the Transparent disc 55 to meet.
  • the piping system in the embodiments may be made of a variety of materials, such as various metals, metal alloys or special plastics, ceramics and also mixtures, such as mixtures of plastic and ceramic.
  • the various components of the Rohleitsystems have different forms in the embodiments.
  • the individual pipes or air ducts can, for example, have a circular or rectangular cross section and the diameter varies depending on the embodiment of the piping system, or depending on the corresponding need for primary and / or secondary air.
  • the secondary air duct is not arranged centrally on the combustion chamber, but for example laterally.
