Definitions

  • the invention relates to a gas-fired water or air heater with a control device that controls both the gas supply to the burner and the combustion air supply.
  • a control device that controls both the gas supply to the burner and the combustion air supply.
  • the gas supply to the burner is controlled by a gas control valve controlled by a temperature sensor.
  • a spring-loaded diaphragm actuator which controls an air flap in the combustion air supply duct, is connected to the output line of the control valve.
  • the closing body 1 or the main gas valve is spring-loaded in the closing direction by a closing spring 2 and is lifted off the seat by a diaphragm drive as soon as the force exerted by the control pressure in the chamber 3 on the diaphragm, that of the outlet pressure in outlet 5 on the opposite side of the diaphragm 4 force acting plus the force of the spring 2 exceeds.
  • the drive chamber 3 receives its control pressure via a channel 6 and a switch-on solenoid valve from the suspension chamber of a servo pressure regulator 7, which is controlled by a temperature sensor 8.
  • servo pressure regulators are described in detail, for example, in DE-PS 26 466 310 and DE-OS 29 03 201 and 29 03 203.
  • a safety valve not shown, is switched on, which can be opened by means of a pushbutton 10 and is kept open by a thermoelectrical ignition protection device 11, as long as the thermocouple 13 associated with the pilot burner 12 is heated by the pilot flame.
  • the outlet 5 of the gas control valve is connected via a channel 14 to the servo pressure regulator 7.
  • the servo pressure regulator 7 If the outlet pressure in the outlet 5 decreases, the servo pressure regulator 7 generates an increased control pressure in the line 6 and in the drive chamber 3, so that the main gas valve 1 is opened further and the outlet pressure rises again.
  • the passage of the main gas valve 1 is also increased when the temperature measured by the temperature sensor 8, for example the water temperature at the outlet 15 of the heat exchanger 16, falls below its setpoint.
  • the servo pressure regulator 7 is also connected to the drive chamber 21 of a servo pressure-controlled air control valve, the closing body 22 of which is in turn biased in the closing direction by a spring 23 and is actuated by a membrane 24.
  • the inlet 25 of the air control valve is connected to a compressed air generator in the form of a fan 26, while the sensor 28 of a flow switch 29 is arranged in the outlet 27. Its make contact, which closes due to the air flow, lies in the excitation circuit of the switch-on solenoid valve in the servo pressure regulator 7. This therefore simultaneously controls the gas quantity flowing through the gas control valve 1 and the air quantity leaving the air control valve 22.
  • the heat exchanger 16 and the main burner 30 are surrounded by a closed housing 31.
  • the combustion gases leave the housing 31 through an exhaust 32.
  • the inlet 33 of the main burner 30 is opposed by an injector nozzle 34, via which gas flows into the main burner from the outlet 5 of the gas control valve. Due to the jet effect of the nozzle 34, the gas stream simultaneously sucks in primary air, which is fed to the main burner 30 as combustion air.
  • the housing 31 has an inlet 35 for secondary air, which is opposed by a further injector nozzle 36. It is from Air control valve 22 is supplied with compressed air and, due to its jet effect, also draws in additional combustion air and presses it into the interior of the housing 31. There it is available to the main burner 30 to achieve the most complete possible combustion. Otherwise, the housing 31 is closed. With the help of a throttle 37, the amount of air supplied to the air nozzle 36 can be adjusted in order to achieve an optimal gas / air mixture.
  • an air outlet nozzle 42 is arranged in the upper part 41 of the flue gas outlet 32, 41 downstream of a train interruption 40, which is connected via a compressed air supply line 43 to the compressed air source consisting of blower 26 and air control valve 22.
  • the connection to the outlet 27 of the air control valve is made.
  • the air flow producing the artificial draft from the nozzle 42 is continuously adapted to the amount of air supplied to the burner.
  • FIG. 2 differs from that of FIG. 1 essentially in that the servo pressure regulator 7 is not placed on the housing of the main gas valve, but on that of the air control valve.
  • this embodiment operates in the same way as described above. It is advantageous that the servo pressure regulator does not work with gas but with air and consequently no gas can escape in the event of any leaks. It can therefore be made from less demanding materials such as plastic.
  • the blower 26 only has to deliver a relatively small amount of air, the use of a servo-controlled air control valve simultaneously regulating any fluctuations in the supply pressure supplied by the blower.
  • the connecting line 43 is directly connected to the blower 26.
  • a throttle valve 47 is provided between the blower as the air source and the air outlet nozzle 42 in the flue gas discharge 41, the drive 48 of which is controlled by a temperature sensor 49 or 49 '. This measures the exhaust gas temperature in the flue gas outlet 41. The lower this temperature is, the further the throttle valve 47 is opened and thus the additional air quantity serving to improve the train is increased.
  • the drive can take place as shown via an expansion temperature sensor 49 and a membrane capsule 48 or through a bimetal or in another way.
