Combustion/Cooling Air Inlet

Supplies combustion/cooling air to the igniter

Eddy Plate

Provides proper mixing of the combustion air and fuel for
reliable ignition and flame stability

Flame Detection Rod 

Integral flame detection for igniter; high temperature
extension with removable flame rod

Oil and Air Connections

Positive shut-off quick disconnects allow easy maintenance,
while 1/4 in. oil and 3/8 in. air connections prevent
accidental switching

Oil Atomizer Assembly

SST construction, produces a finer spray, reduces particulate
and opacity emissions, minimizes atomizer plugging

PAI Spark Probe

High temperature extension with removable spark plug

Seal/Aspirating Air Connection (pressure-fired units only)

Seal air chamber allows removal of the spark and flame rods
and the oil atomizer

Spark and Flame Rod Connections

Flexible conduit connections allow removal of the flame and
spark rods without electrical disconnects

Stationary Guide Tube

Stationary guide tube with stainless steel end mounts easily
into the burner

Ignitor Upgrade Success Story

American Electric Power (AEP) Amos Power Plant, West Virginia, USA

When plant operators observed that the unit could not light off, they called upon Babcock & Wilcox (B&W) to help assess the condition of the ignition equipment and develop a plan to refurbish it to safe, reliable operation.
