For corner-fired boilers originally developed by Combustion Engineering (CE)/Alstom, B&W offers FPS gas and oil horn ignitors. These horn ignitors integrate electrical and mechanical components to optimize performance of ignition reliability, combustion, flame stability, and flame monitoring.

Features of the FPS horn ignitor:
Easy installation and maintenance – Our horn ignitors are shop assembled onto the mounting plate so that the internal components insert through the windbox air chamber and into the ignitor horn. The ignitor assembly can be easily withdrawn for maintenance.

Plasma arc ignition system – To prevent the common problem of spark plug fouling on horn ignitors, and to provide reliable light-off over the long term, FPS horn ignitors are equipped with the plasma arc ignition (PAI) system which provides pulsed high energy sparks during the ignition trial time.

SunSpot flame detector – Both the gas and oil horn ignitors are equipped with the integral Sun Spot flame detection system, a proven flame rod technology for detecting the ignitor flame while discriminating from other flames in the boiler.

• Discrete flame detection
• No periodic maintenance requirement
• No field calibration
• No delicate optics to break or get dirty
