Definitions

  • the invention relates to an oven or a small combustion system with an automatic feeding device for solid, free-flowing fuels to a combustion chamber.
  • the present invention proposes an oven or a small combustion system with an automatic Feeder for solid, free-flowing fuels a combustion chamber, which is characterized according to the invention through a central air supply, the air outside the Installation room of the furnace sucks. This also allows it to heavily soiled combustion chamber and one caused by it The vacuum in the combustion chamber no longer collapses to a pressure drop between the combustion chamber and the installation room come as the installation room through the stove or the Small combustion system no more air is extracted.
  • the air supply can have an air duct, which opens into the combustion chamber and with at least one air branch is provided.
  • the proportion of air flowing to the combustion chamber is the combustion air, while the branched air is too other purposes, for example for cooling individual furnace areas, can be used. It is advantageous if in the air duct and / or in the air branch or branches Air flow sensors are provided. It is possible one or more fans of the air supply and / or Valve devices on the branches depending on to control the sensor signals in order to always have optimal operating conditions to be able to guarantee.
  • One of the air branches can, for example, lead to the feed device for the fuels and cool them, which creates the risk of backburning into a storage container for the fuel is minimized. It is also possible to get one Air branch to an ignition device for the fuels provided. In addition, an air diversion to one Guide the combustion chamber so that it passes through the Air can be purged.
  • the combustion chamber is at least is surrounded on three sides by an air chamber with the air duct is connected.
  • This air chamber isolates the combustion chamber to the outside. This will make it stable Flame kinematics and a constant combustion process achieved.
  • a fuel chute can pass through the air chamber the supply device for the fuels under insulation be led through to this. So that is a thermal Decoupling of the feeder guaranteed.
  • Another measure to prevent a burn back in a reservoir for the fuels can be reached be that in a connection area between the Fuel slide and one with a fuel storage container connected conveyor of the feeder for the fuels with the drive device of the conveyor connected temperature sensor and / or a replaceable one Safety route with a fire protection laminate is provided, the fuel supply in the event of overheating blocked, are provided.
  • the Temperature sensor switching off the conveyor for the Fuels or a safety device, for example a sprinkler system.
  • the fire protection laminate can block the further fuel supply. This absolutely ensures that flames or Do not put hot heating gases from the combustion chamber into the storage container or the conveyor for the fuels can.
  • the stove can heat a room solely by radiant heat Afford. However, it is also possible to use it as a kettle To operate central heating and it with a water heat exchanger to provide.
  • the pivotal movement of the fire grate can occur automatically, so that a measure Malfunction due to increasing clogging of the fire grate can be avoided.
  • the furnace 10 of Fig. 1 the surrounding space by waste heat heats, has a combustion chamber 11, one arranged above Heat exchanger area 12 of the heating gases with the ambient air, a storage container 13 for fuels, in particular for Wood pellets, and a conveyor 14 for the fuels on.
  • a central one Air supply 15 On the back of the furnace 10 is a central one Air supply 15 arranged, with the air outside the installation room of the furnace 10 can be sucked.
  • the central one Air supply 15 has an air duct 16, which is connected to the combustion chamber 11 and thus combustion air feeds.
  • An air quantity sensor is in the air duct 16 17 arranged, via which a suction fan 18th can be controlled.
  • the combustion chamber 11 is one Surround air chamber 19, which is connected to the air duct 16 is.
  • the Safety route 24 is also with a fire protection laminate 26 lined that after exceeding a limit temperature blocked the passage through the security route 24.
  • the fuel tank 13 is relatively wide in space separated from the combustion chamber 11 so that the furnace 10 as a whole multiple protection against backburn in the fuel tank 13 has.
  • a grate 28 is arranged, which means of a motor 29 is pivotable.
  • the furnace 30 shown in FIG. 2 essentially corresponds Components of the furnace 10 from Fig. 1.
  • a central air supply 35 is provided with which a combustion chamber 31 is supplied with combustion air.
  • the combustion chamber 31 is also surrounded by a cooling air chamber 39.
  • Above the combustion chamber 31 is the area guiding the flue gas 32 provided, but now leading from a water Coat 40 is surrounded.
  • the jacket 40 encloses the Area 32 on the back, on both sides and from above.
  • the furnace 30 can thus be used as a boiler for hot water heating be used.
  • Fig. 2 is also the way of the sucked Air marked by arrows 44. After splitting a first partial flow of air 44.1 reaches the fuel slide, a second section from above via the air chamber 39 into the combustion chamber 31 and a third partial flow 44.3 from below through the grate 48 into the combustion chamber 31.
  • Fig. 3 illustrates that the furnace 30 except the outer water jacket 40 still an inner water jacket 41 and 42 to Has area 32 leading both sides of the flue gas.
  • the hot flue gases are along the arrows 43 between passed through the two water coats 40 and 41 and 42, thus making optimal use of the heat capacity of the flue gases is guaranteed.
  • a manually or automatically operated cleaning device 45 provided for cleaning the heat exchanger surfaces.
  • the sectional view according to FIG. 4 illustrates once again in the top view the central air supply 35 and the air path 44 through the branch 44.1 to the fuel slide 32. You can also see the grate 48, the motor pivoted and can be cleaned.
