Pilot assemblies comprising a fire path tubing and pilot tubing in fluid communication through a pilot nozzle for burning waste gases in enclosed ground flares and elevated flare stacks are disclosed. A plurality of flame segments is generated using a hot surface ignition element in the fire path tubing and ignites fuel/air mixture flowing through the pilot tubing into a pilot nozzle to produce a reliable pilot flame. Methods for operating the pilot assemblies are disclosed.

A heater of the disclosure includes: an insulating base including a rod-shaped portion; a heat generating resistor located inside the insulating base; a fixing member which is cylindrical, wherein the insulating base is inserted into the fixing member; and a spacer which is belt-shaped, located between the rod-shaped portion and the fixing member, and surrounds the rod-shaped portion in a circumferential direction. The spacer includes a first end and a second end which face the first end.
