B&W offers replacement FPS dual fuel horn igniters for corner-fired boiler applications.
Our in-depth knowledge in the field of ignition equipment has enabled us to implement significant design improvements and produce efficient, reliable igniters for either partial upgrades or complete replacement.
The dual fuel horn igniter is designed to burn light oil providing up to 6 million Btu per hour heat input and natural gas providing up to 8 million Btu per hour heat input. Both the oil and gas internals remain in place simultaneously, and either fuel can be fired with the flip of a switch.
All horn igniters use the SunSpot flame rod for flame detection and a self cleaning plasma arc ignition system (PAI) for spark ignition. A strong blow torch type flame ensures excellent main fuel ignition.
FPS dual fuel horn igniters are designed to fit standard competitor windbox arrangements. Custom designs are available for applications where the original burner structure has been modified. The horn igniters are supplied with a mounting/adapter plate and gasket to mount on the existing bolt arrangement, making igniter installation very simple. The igniter is designed to use existing windbox air, with an option available for an external combustion air system. The igniter can be mounted in existing horns or if required, new cast stainless steel horns with mounting hardware, are available to replace deteriorated or damaged horns. A local control cabinet/valve rack and an external air system are available if required.
Each dual fuel horn igniter is supplied with the following environmentally sealed peripheral components:
- Plasma Arc Ignition (PAI) power pack in a NEMA 4 enclosure
- SunSpot flame detector electronic module
- Gas hose with swivel connector
- Oil hose with quick disconnect coupler
- Atomizing air hose with quick disconnect coupler
- (2) Brass-braided flex conduit assemblies for igniter electrical connections (flame detector and spark ignition)
- Igniter mounting plate with gasket
