  • the combustion gases are then passed through a heat exchanger of the steam humidifier, so that they heat the water surrounding the heat exchanger, which leads to the generation of steam.
  • a gas-operated steam humidifier is, for example, the Condair GS product from Condair AG (see http://www.waltermeier.com/international/sky/en/product_e_1/dampfbefeuchtung.html).
  • an exhaust device for a firing system in particular a gas-operated steam humidifier, which can be integrated into an existing building without great constructional effort, so that exhaust gas from the firing system can be dissipated in a simple way. It is a particular object of the invention to provide a system with an exhaust device for a firing system, by means of the exhaust gas of the firing system in a permissible manner in an exhaust duct of a room ventilation system of the system initiate and can dissipate through this to the outside.
  • the term "in a permissible manner” refers to the fulfillment of technical safety regulations, as prescribed in particular by state laws and regulations, compliance with which, for example, the Technical Inspection Association (TÜV) and the German Association of Gas and Water (DVGW) and is checked by these and by chimney sweeps.

  • exhaust air includes the air flowing out of the rooms / extracted air before and after one (or more) provided in the exhaust duct of the ventilation system fan.
  • a throttle valve is arranged, which serves to adjust the pressure working range of the furnace. Upstream of the throttle valve in the exhaust pipe, a draft limiter is arranged, which serves to stabilize the pressure in the exhaust pipe.
  • the exhaust device of the system comprises an air flow monitor arranged in the continuous duct of the air conditioning system, by means of which the air flow velocity prevailing in the exhaust air duct can be determined and the gas-operated steam humidifier can be controlled as a function of the determined air flow speed.
  • Terms such as “upstream” and “downstream” refer to the operation of the inventive exhaust device.

  • the throttle valve By means of the throttle valve, the working range of the furnace is set. The more the throttle is brought to a closed position, i. the more it closes off the exhaust pipe, the more the negative pressure in the exhaust pipe resulting from the exhaust air flow decreases. At the same time, the throttle valve position influences the overpressure created by the combustion process taking place at the burner of the combustion system. The further the throttle valve is closed, the greater the effect of the overpressure of the burner.
  • the throttle valve is located in the exhaust pipe preferably as close as structurally possible at that open end of the exhaust pipe, which is / is introduced into the exhaust air duct.
  • the throttle valve is provided in the introduced into the exhaust duct / to be introduced portion of the exhaust pipe.
  • the setting of the throttle valve is made and fixed, in particular sealed, prior to commissioning of the inventive exhaust device or the inventive system depending on the structure of the system and the rated power of the furnace.

  • a differential pressure monitor for example, a commercial differential pressure monitor of the company Condair AG or the company Karl Dungs GmbH & Co. KG can be used. Since the differential pressure monitor monitors the pressure in the exhaust pipe, it does not necessarily have to be pressure-tight.

  • the Abgasverteiltician is preferably designed as a tube which extends transversely to the direction of exhaust air flow direction and having a plurality of openings for the exit of the exhaust gas of the furnace in the exhaust air duct.
  • the openings in this case point in the direction of the exhaust air flow, so that the exhaust gas inlet takes place in the exhaust air flow in the flow direction and in this way back pressures and inflow of the exhaust air can be avoided in the exhaust pipe.
  • the openings are uniformly distributed over the length of the Abgasverteiltician to allow a uniform in the transverse direction of the exhaust air duct discharge of the exhaust gas.

  • the specified airflow velocity limit value results from safety regulations, eg for the protection of the environment, in particular in accordance with DVGW G 631. To ensure sufficient dilution of the exhaust gas in the exhaust air of the exhaust air duct before the exhaust air is blown into the atmosphere with the exhaust gas , this preset air flow velocity limit must not be exceeded. As already stated, its falling below for safety reasons leads to the shutdown of the furnace.
  • the air flow velocity limit value (also called the minimum air flow rate) for the exhaust air duct is in particular 50 m 3 / h per kW rated output of the combustion plant.

If the determined pressure value exceeds the upper pressure limit, then the furnace or its power supply is switched off with the aid of the differential pressure switch. Accordingly, the combustion system or its power supply is switched off or kept in an off state when falling below the lower pressure limit, so that switching on the furnace by the differential pressure monitor is prevented until the determined pressure above the lower pressure limit (and below the upper pressure limit) lies.
  • the differential pressure switch used in particular fulfills the requirements of the standard EN 1854.
  • the upper (lower) pressure limit is in particular at -20 Pa.

  • the lower pressure limit applies to the off state, e.g. when the gas-powered steam humidifier is in standby mode.
  • the firing system is switched off by the differential pressure switch. If, in contrast, the pressure falls below the lower pressure limit value in the exhaust gas line, this can happen when the firing system is switched on As a result, the flame is drawn from its burner in the exhaust pipe. To prevent this, the differential pressure switch in this case prevents switching on the firing system. Maintaining the upper pressure limit for the furnace and the lower pressure limit for the deactivated combustion system will allow optimal combustion in the furnace.
  • Turning off the furnace or its power supply is also referred to as locking the furnace.
  • the flue gas of the combustion plant is discharged in a simple and safety-permissible manner via the exhaust air duct of the ventilation and air-conditioning system.
