Definitions

  • this is achieved in a burner of the type mentioned in the introduction in that a stationary mixing head with outlet openings for a combustible gas mixture is arranged at the outlet of the gasifier.
  • a stationary carburetor which has an inlet proximally and an outlet distally, a flame tube which surrounds the carburetor, the space between the carburetor and flame tube serving as a recirculation path for hot combustion gases to the carburetor inlet, a fuel supply to the carburetor and one stationary mixing head at the exit of the carburetor.
  • This combination contains no moving elements and is therefore very reliable.
  • an electric heater is expediently arranged on the carburetor.
  • the carburetor is then heated up before the fuel supply is switched on. In this way it is avoided that unburned hydrocarbons are released to an unacceptable extent at the beginning of the heating process.
  • the carburetor, mixing head, deflection part, air panel and electric heater advantageously form a single structural unit. Such a unit can be easily replaced during service work.
  • a Volustat can be provided to control the fuel supply.
  • a volustat is understood to mean a device which, according to an input signal, delivers a corresponding delivery volume per unit of time, which is practically not influenced by resistances in the delivery line. The delivery volume is hardly influenced by the viscosity of the fuel.
  • the unit 45 consisting of the carburetor 17 and the mixing head 29 is fastened to the air shield 35 by spot welding, rivets or the like, for example with three feet 47, which can represent extensions of the tube 30. Through the Gaps between the feet 47 create recirculation inlets 49.
  • a spray rotor 18 is provided instead of an atomizing nozzle 54, which is driven by the motor 11 (FIG. 1) via the shaft 20.
  • the fuel line 19 leads in the immediate vicinity of the spray rotor 18.
  • the ignition electrode 65 projects into the carburetor chamber.
  • the ignition in the carburetor chamber has the advantage that a pressure surge during ignition is largely avoided. So there is a soft start. The ignition also takes place quite quickly because at the start in the carburetor 17 the temperatures are higher than at the outlet openings 33 of the mixing head 29.
