Ignitors for Wall-Fired Boilers
FPS Ignitors are suitable for replacing existing
ignitors and for installation in new burners on utility boilers,
package boilers, lime kilns, bark boilers, and recovery boilers.
For retrofit applications the FPS ignitor is designed as a plug-in
replacement for existing ignitors, requiring minimal, if any,
burner modification.
The ignitors are available in either fixed or retractable
models, and are capable of firing No.2 Fuel Oil, Propane, or Natural
Gas. Dual fuel models which fire oil and gas are also available.
All FPS Ignitors have excellent turndown ratios.
Combustion air may be sourced from the windbox
or from an external fan. A clean external combustion air supply
is recommended for coal-fired applications, to prevent problems
related to flyash accumulation on ignitor components. Fossil can
supply suitable combustion
air assemblies as part of an ignitor package.
The ignitors can also be supplied with integral
controls and/or
customized valve
trains.
FPS Ignitors are equipped with a guide tube housing
which extends through the burner or windbox, simplifying installation
and providing protection of the internal components. A stainless
steel guide tube end guarantees extended service life. Fabrication
of the ignitor assembly is done so that components which may require
periodic maintenance or replacement are easy to remove, service,
and replace.

Models:
Oil
Ignitors – The FPS Oil Ignitors burn No.2 light
oil and are available from 4 to 17 MBtu/hr.
Gas Ignitors –
The FPS Gas Ignitors are available from 0.25 to 20 MBtu/hr.
These ignitors are capable of burning natural gas, propane,
and other fuels such as butane.
Dual Fuel Ignitors
– This ignitor combines the internals of both the oil
and gas models to achieve a dual fuel package.
