Description
The Fireye SP-48-NG-ND-1.1 is a SureFire II natural-gas pilot igniter used to light oil- and gas-fired main burners in industrial heating equipment. Its 1.1 m (3.60 ft) insertion length reaches into the burner assembly, and the air tube measures 48 mm OD. The pilot operates at 20–46 kW with a natural gas pressure of 20–80 kPa.
Combustion and cooling air enter through openings in the air tube, with a sliding sleeve regulating the intake. Natural gas passes through the 1/2" BSP female inlet to the orifice-stabilizer assembly, where the pilot flame is established. The assembly maintains flame stability during intermittent light-off or continuous operation, with HESI or HTI ignition equipment specified separately.
