initer These three features combine to produce a highly reliable igniter. The HESI produces a consistent spark due to its foul resistant design, while the optical detector proves flame without physical contact.
Product Overview Product Overview The Forney horn igniter is used on tangentially fired boilers for burner ignition and warm up, typically as a Class 2 igniter. Depending on customer needs, Forney offers either a single or dual fuel horn igniter.
The single fuel horn igniter fires either oil or gas. The dual fuel horn igniter fires either oil or gas without a change of equipment, allowing for a quick and effortless change over of fuel.
Ugniter horn igniter assemblies consist of a mounting plate, an oil or gas gun for the single fuel horn igniter or a combination oil and gas gun for the dual fuel horn igniter, a High Energy Spark Igniter HESIa combustion air tube, an optional flame detector, and a horn.
The major components are fastened to fofney igniter front plate with easily removable connections to simplify maintenance. The oil and gas connections utilize stainless steel braided hoses and optional quick disconnect couplings.
Fofney the etector is mounted to the igniter windbox, it does not require cooling air. On retrofit applications, the existing horn diffuser may be reused, if it is not damaged or deteriorated. As a result, the installation requires only replacing the front plate and internal hardware, minimizing costs.
ighiter Horn Igniter The Forney horn igniter is designed to be a direct replacement for the OEM igniter on tangentially fired boilers. Depending on burner capacity, the horn igniter is capable of supporting Class 1 or 2 operations.
