Estimating the term…
One embodiment relates to a burner, comprising a fuel pipe, a fuel nozzle, at least one ignition and/or heat source and a pipe which conducts an oxygen-containing gas and/or recirculated flue gas, wherein the at least one ignition and/or heat source is arranged in the burner interior and is in the form of or comprises an electric heating and/or ignition device via which, exclusively by conversion of electrical current into heat energy, the amount of heat energy required within the burner for the initiation and continuation of the initial pyrolysis and ignition is generated and/or provided in the burner interior. A stabilizing ring with toothed ring may be a constituent part of the electric heating and/or ignition device arranged in the mouth region of the fuel nozzle.
A burner, in particular coal dust burner, comprising a fuel pipe, a fuel nozzle, at least one ignition and/or heat source and a pipe carrying an oxygen-containing gas and/or recirculated flue gas, wherein the at least one ignition and/or heat source is arranged in the burner interior and is formed as or comprises an electrical heating and/or ignition device, which generates and/or provides the amount of thermal energy required within the burner for the origination and execution of the initial pyrolysis and ignition in the burner interior, in particular in the region of the fuel ignition site forming, exclusively by conversion of electric current into thermal energy,
