B&W offers several FPS products for upgrading and improving performance of existing igniters on corner-fired boilers.
The upgrade offerings are the result of continued research and development and include:
- replacement horns
- igniter booster guns for oil igniters
- SunSpot Flame Detector retrofit kits
- Plasma Arc Ignition (PAI) systems for oil igniters
- flow regulators for oil igniters
- control box/valve assemblies
Horns with holes or severe cracks in the horn wall will adversely affect igniter operation. B&W offers a single pour, cast stainless steel horn, equipped with mounting plates to match the existing configuration.
Igniter Booster Guns for Oil Igniters
The FPS igniter booster package increases heat input up to 14 million Btu per hour, bringing the total igniter heat input to 20 million Btu per hour. The igniter booster gun consists of an additional oil atomizer mounted on top of the igniter horn. Installation of the booster gun requires minor modifications to the igniter horn and igniter mounting plate. The booster package is supplied with oil and atomizing air hoses with quick disconnect couplers and a pressure regulator.
SunSpot Flame Detector Retrofit Kit
The SunSpot Retrofit Kit is
available to replace
P (differential
pressure) type flame detectors on gas or oil igniters on corner-fired boilers.
The easily installed retrofit kit requires no modification to existing igniter
hardware. The SunSpot II flame detector utilizes ionization and flicker
characteristics to sense the flame in an igniter. It is supplied as standard
equipment on all FPS igniters.
Plasma Arc Ignition (PAI) Systems for Oil Igniters
B&W offers an efficient FPS spark
ignition system to overcome the common problem of carbon build-up on the spark
plug in older horn igniters. Over time this carbon build-up reduces reliability
of the igniter spark, and consequently the igniter.
The PAI system is designed to provide a high output pulsed spark (3 sparks/second) for the forceful ignition of fuel oil. Each powerful spark pulse creates a shock at the spark plug tip, which disperses any material collecting on the tip of the spark plug. This continuous cleaning of the spark tip reduces the need for manual cleaning characteristic of continuous voltage ignition systems.
The PAI can be easily retrofitted on existing oil horn igniters and ensures optimal sparking for effective ignition.
The benefits achieved with this upgrade are:
- Self-cleaning spark tip that eliminates carbon build-up on the spark tip thus improving reliability
- Low output voltage of 2,000 Vdc versus 10,000 Vdc found on other igniters
- Surface gap provides more surface for arc, lessening erosion, resulting in longer life
Flow Regulators for Oil Igniters
The FPS flow regulator
is designed to improve the operation of oil horn igniters. The igniter oil
supply is regulated to the optimal level required to achieve efficient fuel
atomization and burning within the environment of the horn. The fuel supply is
connected to the 1/4" NPT inlet at the middle of the regulator body and the
outlet is connected to the 1/4" NPT connection at the top of the regulator
body. There are no flow adjustment or calibration settings on the device.
Service is limited to cleaning any debris that may collect inside the
regulator.
B&W
offers an FPS igniter control box/valve rack assembly specially designed to match
the layout of corner-fired boilers. The assembly consists of a NEMA 4 control
box with door mounted pilot devices to allow local control and monitoring of
igniter operation. The control box houses the SunSpot flame detector electronic
module and field terminals for the igniter and igniter electrical valve
connections. Attached to the bottom of the control box are valves to supply
fuel and air to the igniters.
