  • the combustion chamber 12 is at least partially accessible from the outside via an opening 104 or the like.
  • an opening 104 is sealingly closable via a, in particular transparent, closing device 106, for example in the form of a window or a door.
  • FIGS. 11 to 13 show another embodiment of a device 10 designed according to the invention.
  • the burner 46 is again designed as a gas flow burner 48.
  • the gas flow burner 48 is assigned a piezo ignition device 108 for igniting the gas / air mixture.
  • the piezo-ignition device 108 is connected via a line 110 to a firing button 112.
  • the gas flow burner 48 is still equipped with a thermocouple 114, which cooperates with a valve 76, in particular a solenoid valve.
  • the valve 76 is arranged in the first supply line 54 for supplying the gas and serves to open and close the first supply line 54 depending on the respective demand for gas.
  • the first supply line 54 for supplying gas to the gas flow burner 48 is first interrupted by the valve 76.
  • regulator 116 which operates the valve 76, the first supply line 54 is released, so that gas can flow into the gas flow burner 48.
  • the thermocouple 114 controls the valve 76 to supply the gas flow burner 48 with the required amount of gas via the first supply line 54.
  • the first supply line 54 is therefore shut off promptly by the valve 76.
  • the arrangement of an exhaust air duct 118 is furthermore different in the embodiment of the device 10 according to FIGS. 11 to 14 to that according to FIGS. 1 to 4.
  • the exhaust air line 84 communicates with the combustion chamber 12 via an upper region 120 of the combustion chamber 12
  • the exhaust port 118 has a length equal to or greater than half the height of the combustion chamber 12.
  • the length of the exhaust port 118 corresponds to about 3/4 to about 9/10 The height of the combustion chamber 12.
  • the exhaust duct 118 is suitably formed by a part of the combustion chamber 12, in particular of the rear side 28 thereof.
  • the exhaust duct 86 is thus configured in cross-section approximately U-shaped and provided with two laterally projecting tabs which are fixed to the jacket 14 made of refractory material.
  • the exhaust duct 118 is also made of stainless steel, in particular stainless steel, to exclude any rust in the combustion chamber 12. During operation of the device 10 according to the invention, it has proved to be particularly advantageous in terms of flow technology that the exhaust air duct 118 has a cross-sectional area which is between approximately 5: 2 to 2: 1 in relation to the cross-sectional area of the exhaust air duct 84.
  • a device 10 according to the invention has proven to be particularly advantageous in a surprisingly simple manner.
  • the device 10 according to the invention may, for example, have the following dimensions and characteristics:
  • the outer dimensions of the device 10 are about 1000 mm ⁇ 740 mm ⁇ 740 mm.

  • the longitudinal support members 38 of the frame 30 have a thickness of 1.5 mm.
  • the burner 46 is equipped with a burner power of about 1.0 kW to about 3.5 kW, in particular from about 1.5 kW to 2 kW.
  • the first supply line 54 for supplying the gas has a diameter of 8 mm, but may also vary in a range of about 4 to 12 mm.
  • the second supply line 56 for supplying the air has a diameter of 34 mm, but may also vary in a range approximately between 20 and 40 mm.
  • the exhaust pipe 84 has a diameter of 50 mm.
  • the efficiency of the device 10 according to the invention is about 97%, the efficiency (due to the heat storage) about 99%.

  • the temperature of the exhaust gas to be discharged through the exhaust duct 84 is about 30 ° C to 50 ° C, preferably 35 ° C to 40 ° C. CO 2 emissions are around 4.7%.
  • an operation of the combustion device 46 with or at a heating power of between approximately 1.5 kW to approximately 2 kW inclusive has proven to be extremely economical.
  • a heating time of nearly 12 hours heat is released due to the storage of heat by the device 10 according to the invention for a further 6 hours.
  • the apparatus 10 according to the invention is a stagnant heat gas storage furnace which is simple, compact and reliable and, due to a specially designed exhaust system, ensures that the heat remains in the apparatus 10 and not through the chimney. as in a conventional tiled stove, led out.
