Features & Beneﬁts

Horn Igniters

IgnIter CapaCIty

Up to 4 MBtu/hr for ignition and/or support

of main gas, oil or coal burners and up to

15 MBtu/hr with an auxiliary gun.

Depending on burner capacity, the horn

igniter is capable of supporting Class 1 or

2 operations.

Dual Fuel CapabIlIty

The single fuel horn igniter fires either oil or

gas; the dual fuel horn igniter fires either oil

or gas without any change of equipment.

Stable Flame

Combustion air is evenly distributed

throughout the horn for reliable operation;

Forney’s design does not include an eddy

plate, thus reducing coke buildup and

overheating.

OptIOnal Flame DeteCtIOn

The flame detector senses flame inside the

horn and discriminates from flames outside

the horn.

relIable IgnItIOn

The High Energy Spark Igniter (HESI) is

fixed at the most efficient light-off position

for repeatable ignition.

e 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. e single fuel

horn igniter ﬁres either oil or gas. e 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. e major components are fastened

to the igniter front plate with easily removable connections to simplify main-

tenance. e oil and gas connections utilize stainless steel braided hoses and

optional quick disconnect couplings.

e 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.
