Pilot torch is an atmospheric pilot with a soft, stable flame designed to operate on low-pressure gasses. The basic components are the AN tip, SPI inspirator, a length of mixing tube and a control valve. This is used to ignite the oil from the main oil guns. It is used when placing a main oil gun in or taking a main gun out of service and to assist in burning any oil scavenged from the main oil gun during the steam purge cycle.
