Definitions

  • the invention is based on an exhaust gas duct and a Heater with exhaust system according to the genus Main claims. It is known that in particular atmospheric heaters are part of the Exhaust gas routing is designed as a flow safety device (e.g. G 88 01 994.2). Such designed as exhaust hoods Flow fuses have side openings, so in the event of a backflow of the exhaust gases through the openings in can reach the installation room. Near the Exhaust gas sensors located in the openings record the exhaust gas flow and the heater is disabled until the fault is rectified Operation set. In addition, the one Room air dependent heater through the chimney draft caused pressure fluctuations by the in the Flow protection arranged openings balanced.
  • a flow safety device e.g. G 88 01 994.2
  • the exhaust gas routing according to the invention and the one according to the invention Heater with such an exhaust system have the Advantage that the height of the heater is not essential is increased.
  • the one equipped with the flow safety device Room air dependent heater on a room air independent Exterior wall heater to convert by the flow fuse removed and through an air-exhaust system, in the form of a coaxial double tube is replaced.
  • the heater itself does not need to be modified.
  • the opening for decoupling the heater from the Heater connected exhaust system is more advantageous Way at the top of the first connector of the Flow protection arranged.
  • the Pressure decoupling immediately behind the exhaust pipe of the Heater instead, so that in the direction of flow seen behind the opening part of the exhaust system no high tightness requirements have to be made.
  • the opening is on the side of the first connection piece an exhaust gas sensor for the detection of back-up exhaust gas intended.
  • the heater Air box surround so that in the event of a leak Exhaust gas parts is prevented from exhaust gas in the Installation room of the heater can occur.
  • the air box itself is an opening for the exhaust gas routing of the heater provided, the diameter of the opening being chosen so is that between the opening edges and the passed exhaust gas duct results in an annular gap that the Supply of combustion air for the fan-assisted Heater guaranteed.
  • FIG. 1 shows the heater according to the invention with the exhaust gas routing according to the invention
  • Figure 2 a sectional side view of the exhaust system with a Representation of the air and exhaust gas flows in normal operation
  • Figure 3 is a plan view of the exhaust system
  • Figure 4 is a Representation of the exhaust gas flows within the exhaust system Backflow of exhaust gases
  • Figure 5 an alternative Exhaust gas routing for the heater shown in Figure 1 use as an external wall unit independent of ambient air.
  • the heater according to Figure 1 has a burner 10, the one Fuel gas-air mixture by a fan, not shown is fed.
  • the burner 10 sits at the top of one Combustion chamber 12 by a heat exchanger unit 14 after bottom and side is completed.
  • an exhaust gas space 16 is arranged on the lowest point of which is not shown Condensate drainage is provided.
  • the Burner and heat exchanger unit and exhaust pipe 18 are surrounded by an air box 20, which at its upper End of an opening 22 for the passage of the exhaust pipe 18th to the outside.
  • the diameter of the opening 22 is so dimensioned that between the exhaust pipe 18 and Forms an annular gap over the opening edges Operation of the heater using the burner 10 upstream fan combustion air are sucked in can.
  • At the level of the opening 22 made in the air box 20 is connected to the exhaust pipe when viewed in the direction of flow 18 a flow control described in more detail below 24 on.
  • the flow fuse 24 has a first connection piece 26, which is gas-tight with the end of the exhaust pipe 18 connected is.
  • the in the first connection piece 26th forming flow channel is via a connector 28 performed in a second connection piece 30, such that the first and the second connecting piece 26, 30 horizontally are staggered.
  • the second Connection piece 30 does not connect to one shown chimney or chimney.
  • first connection piece 26 At the upper end of the first connection piece 26 is one Opening 32 provided which connects the Flow control 24 or the exhaust system with the Installation room of the heater.
  • Exhaust gas sensor 34 for the detection of back-up exhaust gas arranged.
  • Baffle 36 for the connector 28 and the second connecting piece 30 flowing into the chimney outlet Exhaust gases provided.
  • the extension of the flow protection in horizontal direction is thereby offset X (see Fig. 2) of the two connecting pieces 26 and 30 determined. This results in a flat flow fuse 24, so that the overall height of the heater is not essential overall is enlarged.
  • the heater works in the following way: About the the burner 10 upstream fan is from the Installation room of the heater via opening 22 Combustion air and a not shown Gas supply device fuel gas supplied to the burner 10. The arising during combustion in the combustion chamber 12 Combustion gases pass through the heat exchanger unit 14 into the exhaust gas space 16 and are shown as exhaust gases (dash-dotted lines shown) via the exhaust pipe 18 and Flow safety device 24 and the adjoining one Chimney drained to the outside. About that in the first Connection piece 26 arranged opening 32 finds one Pressure decoupling of the heater from the rest Exhaust gas discharge instead; at the same time air comes out of the Installation room via the opening 32 in the exhaust duct, see above that the exhaust gas is diluted and thus the dew point is lowered becomes.
  • Exhaust gases reach the exhaust gases through the opening 32 in the installation room of the heater.
  • the exhaust gases are detected by the exhaust gas sensor 34 and the heater after a pause of about 20 minutes started again automatically.
  • room condensing condensing condensing boiler can be used in old buildings, for example, where one Refurbishment of the chimney has not yet taken place. Is the old chimney with a new air exhaust system replaced or is in the chimney a new air-exhaust system the heater can be integrated simple way in a room independent fully condensing heater.
