Combustion air is evenly distributed

Forney’s design does not include an eddy

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.
Both 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 (HESI), a combustion air tube,
an optional flame detector, and a horn. The major components are fastened
to the igniter front plate with easily removable connections to simplify main-
tenance. The oil and gas connections utilize stainless steel braided hoses and
optional quick disconnect couplings.
The optional flame detector is mounted on a 1” NPT sight tube, which
provides an unobstructed view of the flame inside the horn. Since the detector
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 replac-
ing the front plate and internal hardware, minimizing costs.
Forney’s horn igniter offers reliable single
or dual fuel ignition and warm-up for
tangentially fired burners and is designed
for maximum flame stability and
detection.
