The heat-intense spark igniter is the most convenient and satisfactory igniter in gas turbines. The main parts of a spark plug are the electrodes, which is the area where the spark is created. The features of a spark plug are the deposition of ignition energy in a short duration (up to 100 milliseconds) and the concentrated region (up to a few millimeters) of the spark. As the frequency, duration and amount of energy can be controlled, the spark plug is convenient to use. The temperature of the spark is around 60 000 K and therefore heats the gases rapidly ensuring ignition in conditions of high altitude and low temperature.
