ABSTRACT:
A burner with an integrated electrical high-voltage igniter and a flame monitor for partly oxidizing gaseous fuels in reactors that are either pressurized or not. A fuel-gas channel communicates with a confusor which opens into an annual fuel-gas nozzle. The fuel-gas channel, furthermore, is surrounded by an annular oxygen channel. Water channels border the confusor and the annular fuel-gas nozzle. The annular fuel-gas nozzle, moreover, has the confusor, and annular nozzle with a reaction zone end, and a diffusor. This diffusor merges into the oxygen channel at an axially parallel radius of curvature. A high-voltage ignition cable extends through the fuel-gas channel and terminates in a metal electrode which is positioned so as to form a spark gap in a space between the tip of the electrode and a metal wall of the burner. In this space within the spark gap, the fuel gas and oxygen mixture is turbulent, whereby the fuel-gas channel provides a reliable and certain ignition of the fuel gas and oxygen mixture independent of gas pressure in that space. The radius of curvature is located at an exit end of the diffusor and extends into the oxygen channel for separation of gas from walls of the diffusor to produce a vacuum in the spark gap space for suctioning the oxygen from the oxygen channel.
