Description
The Fireye SP-48-NG-ND-1.2 is a SureFire II natural-gas pilot igniter that establishes the flame used to light oil- and gas-fired main burners. Used in industrial heaters and boilers, it has a 1.2 m (3.93 ft) insertion length and a 48 mm outer-diameter air tube. Its natural gas capacity ranges from 20–46 kW at 20–80 kPa.
A 1/2" BSP female inlet feeds natural gas to the orifice-stabilizer assembly, where a small gas flow mixes with air and ignites near the stabilizer plate. The sliding sleeve adjusts natural-draught combustion and cooling air entering the tube. The pilot accepts separately ordered HESI or HTI ignition equipment with rods up to 16 mm OD.
