Definitions

  • the invention relates to an apparatus and a method for controlling the fuel gas-air ratio of a gas-powered burner.
  • EP 1082575 EP 1207347 .
  • EP 1179159 and EP 1084369 are devices and methods for controlling the fuel gas-air ratio of a gas-powered burner known, which has in common that a throttle is arranged in the combustion air and Brenngasweg, the fuel gas in the Verbrennungs Kunststoffweg always takes place downstream of the throttle in the combustion air and combustion air and Brenngasweg each static pressure is removed.
  • Throttle cause throttle losses and thus reduce the overall efficiency.
  • the invention has for its object to provide an apparatus and a method for controlling the fuel gas to air ratio of a fuel gas burner, which is characterized by low pressure losses and high control quality.
  • FIG. 1 shows a control device for a fuel-operated burner 5 with a controllable fan 1, a combustion air line 3, which is connected to the blower 1, a fuel gas line 4, in which an adjustable via an actuator 10 fuel gas valve 2 and which opens into the combustion air line 3, and a pressure or flow sensor 6, which is arranged between the combustion air line 3 and the fuel gas line 4.
  • a first Pressure receiving points 7 In the combustion air line 3, a second pressure receiving point 8.
  • the two pressure receiving points each take on the total pressure. Accordingly, their openings are directed against the flow direction.
  • no further separate aperture is arranged.
  • a displaceable insert 9 is arranged; this can be moved in the extension direction of the combustion air line 3.
  • a control is connected to the pressure or flow sensor 6, the actuator 10 and the fan 1. If the movable insert 9 is adjustable by motor, it is also connected to the controller 11. In FIG. 1 the fan 1 between the combustion air duct 3 and the burner 5 is arranged. Combustion air line 3 and fuel gas line 4 both open into the fan. 1
  • blower 1 in a device according to FIG. 2 arranged in the combustion air line 3 upstream of the pressure receiving point 7.
  • FIG. 3 shows the combustion air duct 3 in plan view.
  • the combustion air duct 3 has a rectangular cross-section.
  • the insert 9 is slidably disposed on the upper wall.
  • FIG. 4 shows the combustion air duct 3 at the height of the measuring point 7 in the side view in the position of the largest flow cross-section
  • FIG. 5 the same combustion air duct 3 at the height of the measuring point 7 in the side view in the position of the smallest flow cross-section shows.
  • the flow cross section around the pressure receiving point 7 around is constant, which is necessary for the control method.
  • the minimum air requirement / min is a measure of how much combustion air per fuel gas is required for stoichiometric combustion.
  • the air ratio ⁇ is a measure of how much air in the air Comparison to the stoichiometric air quantity is present.
  • c is the flow velocity and A is the area.
  • p dyn denotes the dynamic pressure of the flowing medium and ⁇ its density.
  • the two gas streams flow unthrottled into one another. Their static pressures are thus the same. In a zero pressure control by means of a device according to the invention, therefore, the dynamic pressures must be equal.
  • the ratio A L / A G is 24 for the same air ratio and 12.3 for low calorific fuel gas (standard gas G27).
  • the adjustable insert 9 is arranged in the combustion air line 3.
  • this insert could also be arranged in the fuel gas line 4.
  • the arrangement in the combustion air line 3 has the advantage that the adjustment mechanism does not have to be completely sealed from the environment.
  • the adjustable insert 9 is displaced, whereby the flow cross-section is set at the height of the pressure receiving point 7.
  • the insert 9 is designed such that both a certain distance before the pressure receiving point 7, as well as behind the air flow cross section is constant. Above mentioned numerical examples show that the air flow cross-section must be approximately halved by means of the displaceable insert.
