FST (Flexible Single Tube)

This Class I igniter is located in a tilting tangentially fired boiler adjacent to the main fuel nozzle.

As an oil igniter, the unique rear atomizer results in a single tube extending to the one piece tip. This design eliminates the need for atomizer maintenance.

As a gas igniter, the gas is directed to the tip through the single flexible tube. Stabilization is maintained by a 7.5 inch swirler which creates a low pressure zone just down stream of the nozzle. Combustion air is provided from the windbox.

 

Forney’s Flexible Single Tube (FST) Igniter provides multi-fuel, stable and reliable ignition for tangential burners utilizing a flexible design for optimal ignition with tilting nozzles.
