Product:\u00a0Flexible Single Tube<\/h4>\n

This Class I igniter is located in a tilting tangentially fired boiler adjacent to the main fuel nozzle.<\/p>\n

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.<\/p>\n

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.<\/p>\n

Forney\u2019s 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.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_tta_tabs][vc_tta_section title=”Product Overview” tab_id=”1535228058413-12a31845-683a5426-2a926f74-14602c81-0904″][vc_column_text]The Flexible Single Tube (FST) Igniter is a reliable source of ignition energy for use in a tilting tangential type boiler. It is a Class 1, continuous duty, igniter capable of burner ignition and low load support. It is easily installed in the auxiliary air nozzles between the main fuel elevations and is designed with flexible components to accommodate the tilting of the fuel nozzles. The FST Igniter is capable of burning liquid or gaseous fuels. With capacities up to 10% of boiler heat input, the FST improves boiler \/ turbine startup flexibility.<\/p>\n

Each FST Igniter includes a flexible fuel gun, a flexible retractable High Energy Spark Igniter (HESI) and a flame detector with a flexible fiber optic assembly. The fuel gun has an air swirler at the furnace end which mixes the windbox air and fuel at the tip to create a stable flame. All major components are fixed to a burner front plate that is designed to match the existing bolt pattern at the burner front. All components are designed to freely tilt with the fuel nozzle through a \u00b130\u00b0 angle. Flame detection is accomplished by the use of either an ultraviolet or infrared detector, depending on the fuel fired.<\/p>\n

Optional equipment includes gun retraction, quick disconnect fuel and atomizing air couplings, as well as an electrical junction box.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Technical Data” tab_id=”1535228058480-927f5ae5-e2315426-2a926f74-14602c81-0904″][vc_column_text]<\/p>\n
