Alstom - Oil Pipe Igniter for T- and Wall-fired Boilers

Print Print
See Product Details

The LIMELIGHT™ high performance oil pipe ignitor has been designed to integrate the latest in combustion technology, flexibility and overall reliability. It is intended to provide users with state-of-the-art technology for increased capacity, flame stability and turn-down capabilities.

This product is applicable for both T-fired and wall-fired boilers.

This ignitor allows for improved combustion airflow by replacing the eddy late with a flow enhanced bluff body. The improved airflow results in lower pressure drop, higher capacity, and greater turn-down capabilities.

The igniter offers reliable ignition and operation at heat inputs up to 4.4 MMBTU/hr.

Flexible by design, the igniter can be adjusted for one flow with a single pressure regulator, or varied flow on an elevation basis with an individual control valve.

This product serves as a high heat output oil igniter for a wide range of applications. It offers a clean and efficient method for boiler warm-up periods and flame stabilization.

The LIMELIGHT High Performance Oil Pipe Igniter and associated flame proving device has been designed to meet all code requirements including the latest releases of the National Fire Protection Association (NFPA).

KEY FEATURES

  • Easy to retrofit with existing ignitors, resulting in minimal conversion costs for upgrade
  • Stainless steel construction
  • Easy removal of the ingitor internals from the guide side for maintenance purposes
  • Allows for turn-down of airflow through the ignitor on an individual basis
  • An upgrade to 3" pipe ignitors or a retrofit to 6" side ignitors
  • High energy ignition incorporating solid rod assemblies
  • Self cleaning spark tip resists fouling
  • Flame proving incorporating solid rod assemblies
  • Quick disconnect wiring harness for each rod
  • Flow enhanced bluff body design replaces eddy plate design with better air and oil mixing, lower pressure drop, and greater turn-down
  • Offers clean and reliable operation with minimal opacity during start ups

BENEFITS TO USER

  • Highly reliable start-ups and operation
  • Available as a Class 1 igniter thereby increasing reliability and eliminating the use of scanners for main burners
  • High turn-down ratio allowing for maximum operational flexibility
  • Reliable flame detection utilizing solid flame rod proving technology
  • Reliable ignition spark during trial time periods for reduced spark plug maintenance

Bluff body oil pipe ignitors provide reliable fuel/air mixing at the point of the electrical ignition source and provide a stable flame with lower emissions to light-off the adjacent burner. This igniter upgrade equipment can be used in existing wall fired ignitor applications.
