A method of igniting and monitoring a high speed burner with which a fuel/oxygen-mixture exits at high velocity from a burner head, wherein the length of the flame is governed by the exit velocity of the mixture. The invention is characterized by placing an electrically conductive pipe in and concentrical with the burner channel for the fuel mixture, by causing a first end of the pipe to terminate close to the fuel mixture outlet of the burner head, by electrically isolating the pipe and by causing the detection of light of the group ultraviolet light, visible light and/or infrared light to be detected at the other end of the pipe, and by causing a spark to be generated between the first end of the pipe and the surrounding burner head by application of a voltage, in igniting the burner. A burner is also disclosed.
