Burner
A burner for the operation of premixing burners, with gaseous fuels or vaporized fuels for the production in a mixer pipe of a homogeneous mixture comprising the fuel, the quantity of combustion air required for the complete combustion of the fuel and additional cooling gas as needed for combustion between 1,100/sup 0/ and 1,700/sup 0/C. This mixture flows to a burner head with a widening cross-section and a burner plate at the wide end where it is burnt at a central main flame bore arranged at the burner plate and several surrounding support flame bores. The flames then pass through a converging burner mouth and a downstream flame guard which protects the flames against the entrance of air or flue gas from the environment, against cooling and against heating until the completion of combustion. The burner mouth and the flame guard are coated by a noncatalytic material. The waste gas at the outlet of the flame guard contains very little nitrogen oxides and is therefore highly suited for further utilization such as foodstuff drying.
