Abstract: The invention relates to a burner arrangement comprising a burner plate (1) having a multiplicity of apertures (2) and a monitoring device for monitoring the formation of a combustion zone (3) extending from the burner plate (1), wherein the monitoring device comprises a cathode (5) provided on a flame-side top (4) of the burner plate (1) and an anode (7) arranged in the region of the combustion zone (3). To improve the thermal stability and thus the durability, provision is made according to the invention for the burner plate (1) to be made of a non-metallic material and for the cathode (5) to be arranged as a separately designed component in the region of the top (4) of the burner plate (1).

Abstract: A method for setting an air ratio of a fuel/air mixture made from a gaseous fuel and air for the operation of a burner, including the steps of: a) determining the mass current of the fuel as a first measured value, b) determining a value for the determination of the Wobbe index of the fuel as a second measured value, c) determining a mass current of the air as a third measured value, and d) controlling the mass current of the air and/or the fuel in dependence on at least two of the measured values so that a specified air ratio ? of the fuel/air mixture is set.

Abstract: A method and device for low-emission, noncatalytic combustion of a liquid fuel. The method includes separately introducing the liquid fuel in a non-ignitable state into a mixing zone, vaporizing the liquid fuel in the mixing zone, separately introducing a gaseous oxidizing agent into the mixing zone, and mixing the fuel and the gaseous oxidizing agent in the mixing zone to create ignitable mixture. The mixing zone is formed so that combustion is not possible even when the ignition temperature of the mixture is reached within the mixing zone. Combustion of the mixture occurs in a combustion zone located down current from the mixing zone.
