Definitions

  • the invention is based on a method and one Device for operating a heater with a Exhaust gas discharge according to the type of the main claims.
  • Generic heaters have the problem that especially in the lower power range that in the exhaust gas contained energy is insufficient, the chimney sufficient heat up strongly and chimneys sensitive to moisture Protect moisture. This problem will still arise reinforced by new regulations that increase the Demand efficiency of heaters. Because of that necessary measures, such as enlargement the modulation range of the burner, the Exhaust gas temperature and that discharged into the chimney Energy reduced even further.
  • the in Billing period may preferably be 24 hours total required for this period Downtime depends on that for that The chimney's sensitivity to moisture Parameters.
  • controller adjust the burner output in each individual switch-on phase constantly to a higher value than the necessary to maintain the target temperature Value and after reaching the target temperature the Power from one to the other switch-on phase for so long downgrades until the limit for the given one Clock ratio is reached.
  • control concept according to the invention can with particular Advantage can also be provided for condensing boilers that the latent heat of the water vapor contained in the exhaust gas exploit.
  • the heater has a burner 10, which is a fuel-air mixture supplied by a blower, not shown becomes.
  • the burner 10 sits at the top of a combustion chamber 12 formed by a heat exchanger unit Heat block 14 is completed at the bottom and side.
  • Heat block 14 is completed at the bottom and side.
  • An exhaust gas chamber 16 is arranged at the outlet of the heat block 14, at its lowest point a not shown Condensate drain is connected.
  • To the exhaust space 16 is followed by an exhaust pipe 18 which is connected to the heat block 14 is attached.
  • the heat block 14 with the burner 10 and that Exhaust pipe 18 are surrounded by an air box 20 which is connected to its upper end an opening 22 for the implementation of the Exhaust pipe 18 has to the outside.
  • the diameter of the Opening 22 is dimensioned such that there is between the exhaust pipe 18 and the opening edges forms an annular gap over which the fan draws the combustion air for the burner 10.
  • the combustion chamber 12 is connected to the exhaust pipe 18 via a Heat block 14 connected bypass channel 24. about hot exhaust gas reaches below the dew point cooled exhaust gas flow in the exhaust pipe 18, whereby a Avoidance of condensate in the further exhaust gas routing avoided become.
  • a flow safety device 26 is located above the air box 20 arranged, the housing 28 via a first Connection piece 30 with the exhaust pipe 18 and a laterally offset second connecting piece 32 with a chimney pipe 34 designed as an exhaust gas discharge connected is.
  • the first connection piece 30 opens into one at both ends closed shaft 36, which up to leads second connecting piece 32 and there a lateral Has exit opening 40.
  • the exhaust gas passed from the exhaust pipe 18 into the chimney pipe 34.
  • the housing 28 has a first secondary air opening 42 at the entrance an annular gap 44 which surrounds the shaft 36 and also leads to the outlet connection 32.
  • the Secondary air opening 42 ensures a sufficient Chimney draft during the operation of the burner 10 and leaves backlog of exhaust gases in the installation room of the heater to step.
  • the housing 28 is also with a second Provide secondary air opening 46 near the connecting piece 32, that of a motor-driven air flap 48 is monitored.
  • the heater has a controller, not shown, which Burner 10 according to the initially preferred Control concept modulating clocked controls. After this Switching on the heater in the morning gives the controller maximum heating output and first switches the burner again when the set temperature, e.g. B. the setpoint for the flow or return temperature has been reached.
  • the regulator saves the heating time that has occurred and compares it with the following downtime, until The burner is switched on again. This can be done by a thermostat monitoring the target temperature prompted or according to one in the controller software stored characteristic curve. If through the gradual Decrease in heating power from a switch-on phase to others the limit value of the predefined clock ratio is reached, the controller increases the burner output again.
  • the air flap 48 is in coordination with the control concept of the burner, the secondary air opening 46 only in the for Chimney drying provided switch-off phases of the Burner free, whereas in the operation of the burner and at switched off heater takes its closed position.
