2. TECHNICAL SPECIFICATION AND OPERATION PRINCIPLE
HDHESI is a High Energy Igniter, working on the principle of cyclic discharging of a capacitive system by a spark
gap, generating 3 sparks of very high energy of 24 Joules per second on igniter rod tip.
Igniter construction
To order a complete HDHESI igniter please specify the following components (see Fig. 2):
– a Spark Rod: 16 mm outer diameter, with replaceable high resistant tip “class 60 Joules” of fixed gap between
electrodes, equipped with j. box IP67 and male cable connector, reference (insertion) length L = 0.8 to 5.0 m;
Part Number HE-ROD-24-xxx where “xxx” is the rod length L e.g. “1.3” means 1.3 m (see Fig. 2).
– the HV Cable: two wire, shielded, OD 15 mm², 4,5kV max, wire 1,5 mm², 5 m long (or 10 m), with female
cable connector on rod side; Part Numbers are: HEC-24-5 (optional 10 m long P/N HEC-24-10).
– the Power Pack: 230 or 115 VAC (selectable in power pack), rated for 3 sparks of 24 J each per second, with
a gland for ignition cable. Power pack printed board including HV transformer 230/115VAC/1150VAC, HV
capacitors, spark gap, circuit components, terminals is mounted in a carbon steel, powder coated IP66
enclosure;
Part Number HE-PP-24, includes: the door key, mounting lugs and a HV cable gland. Stainless Steel version
of Power Pack enclosure is available on request - contact Fireye.
Igniter operation
During the burner Trial for Ignition the HDHESI igniter is activated by connecting the power pack to a power
supply. Before it is connected check if the correct voltage has been selected on the Power Pack HV transformer
terminals (230VAC or 115VAC is prewired following the order spec). If not, make proper connections following
p. 4, wiring diagram Fig. 4 and Fig. 8. Once energized, the HV ignition transformer generates an 1150 VAC for
secondary circuit. This voltage is doubled to 2300V and rectified. HV capacitors are charged to the level at which
the spark gap causes energy discharge and the cycle is repeated. At the moment of discharge, current flows via HV
cable to the tip of the rod and creates a powerful spark of 24 Joules at the end of the rod tip (see Fig. 2, 4, 6),
between the central positive electrode and the grounded rod outer tube (negative electrode).
After the Trial for Ignition the SureFire II™HDHESI igniter must be disconnected from the power supply.
The circuit is equipped with discharging resistors which allows a quick discharge of capacitors, below 90
seconds, from when the igniter power supply is disconnected.
Only after this period the power pack enclosure can be opened, and service works can be undertaken.
The igniter is designed for continuous use, however the type of applications for which he is intended to be
used is intermittent operation. Following applicable standards, typical Trial for Ignition operating time is 5 - 10
seconds, repeatable in short periods. Operating time in such cases should not exceed time of few minutes. In order
to protect the device from unintentional continuous operation, adequate time delay protection must be
provided in the control system.
The igniter Power Pack can be equipped with a spark proof relay confirming the igniter operation. A rail mounted
current overflow indicator for mounting outside of the power pack, can be offered on request only.
Application features
The design of the unit provides a very stable and repeatable 3 sparks per second of 24J each.
Replaceable, high strength and durable rod tip does not require regular cleaning due to the high energy of the spark.
It is provided with a concentrically arranged electrodes which ensures a constant distance between them.
The use of replaceable tip, high quality materials used and lack of parts requiring adjustment ensures long operation
with low maintenance costs.
Basic principles on the HDHESI igniter use
a) Rod should be mounted in a guide tube of diameter not less than 1”.
In case of very hot and/or dirty applications guide tube should be cooled/purged by air.
b) During ignition, igniter rod tip location should be at least 100 mm deep in the burner fuel cone (zone of the air-
fuel mixture), close to the nozzle of the burner (see Fig. 3).
c) After ignition the rod has to be retracted at least 400 mm back in such a way that rod tip should be hidden
at least 100 mm deep in guide tube (see Fig. 3).
d) Fireye offers coaxial retraction systems, refer to SF-2001 High Energy Igniter technical bulletin.

e) Strictly observe the temperature limits for individual parts of the igniter - see p. 3. In the case of expected
work at the limit of permissible operating temperatures, appropriate measures should be taken (e.g.
change of the mounting position and method of fixing, use of purge-cooling air).
f) In special or difficult applications, consult Fireye.

4. MOUNTING OF THE IGNITION DEVICE
4.1 The igniter function of HDHESI is activated by connecting the power pack to a power supply (230 or 115
VAC). So, before it is connected, check the supply voltage (230VAC or 115VAC) and check the connections
on transformer terminals. It should be wired following order spec. to 230VAC or 115 VAC. If they do not
match, change transformer supply wiring following wiring diagram Fig. 4 and Fig. 8.
4.2 The power supply should be connected in accordance with the igniter's schematic diagram of the power pack
board and igniter wiring diagram for power pack and rod (see Fig. 4), with particular attention to the correct
grounding to the plant grounding system, following the local codes.
4.3 Igniter must always be used in accordance with its intended purpose and following approved installation
documentation, operation algorithms and procedures as well as service manuals.
4.4 Check environmental conditions and ensure that the specified operating temperatures of components as in
p. 3 will not be exceeded.
4.5 During the rod mounting and aiming the conditions and recommendations mentioned in p. 2 should be observed
(see also below).
4.6 Rod should be mounted in a guide tube of diameter not less than 1” and a retraction for the HDHESI rod should
be used to retract igniter rod tip to the safe place after Trial for Ignition (please refer to SF-2001 High Energy
Igniter technical bulletin). The tube must allow the rod tip to reach the correct position in primary combustion
zone to ignite the fuel-air mixture and ensure correct operating temperature and tip protection (please follow
recommendations in p. 2 and Fig. 3).
When HDHESI ignition rod is being used in high temperature applications:
- always use retractor with min. stroke 400 mm to pull the tip back inside the guide tube,
- increase the guide tube length so that the rod tip is completely hidden in guide tube when
retracted,
- use purging / cooling air in the tube to cool the rod and push away a dirt.
4.7 Mounting of the igniter in a retractor: the igniter's rod should be placed inside the guide pipe and fixed in the
retractor clamps. Mounting of the igniter in a retractor must be done so as to enable adjustment of the rod tip
position relative to the burner's nozzle. See retractor Instruction Manual SF-2001 and burner manufacturer
recommendations.
4.8 The guide tube should not be placed in the flame.
4.9 The power pack enclosure should be positioned as close to the burner as possible to reduce cable lengths, as
energy is lost with increasing cable length. The control box must be in a location where the temperature does not
exceed at any moment its max. operating temperature. The box should be mounted with cable glands at the
bottom, to reduce moisture as well as dust and dirt ingress.
4.10Choose the correct glands depending on the cable type and environment demands. After installation, check if the
glands are correctly tightened.
4.11The HV cable should be placed away from any hot elements. It is shielded but not armored, so it should be
mounted in conduits, tubes or cable trays in order to reduce the possibility of damage.
NOTICE: CHECK IF THE LOCAL REGULATIONS ALLOW FOR DIRECT IGNITION OF PARTICULAR

5. OPERATING INSTRUCTIONS
INDUSTRIAL HEALTH AND SAFETY ISSUES. STORAGE, HANDLING, TESTING:
5.1 The igniter, unless mounted on the burner, should be stored in a dry place, protected against mechanical
damage. Do not hit, step on igniter components.
5.2 The rod should be transported with care, avoiding impact against other objects or bending.
It should not be lifted by its ends to ensure no damage to rod, tip and connections.
5.3 Prior to starting the igniter it is necessary to check the condition of the cable, glands and connector for
mechanical damage and make sure that the power pack enclosure and rod j.box are properly closed and
glands are tightly fixed.
5.4 Powering the igniter's circuit should only be done after complete assembly of the rod, tip and only when
fitted in its operation-ready position at the burner. Check the proper insertion depth inside the burner as well
as the position of igniter rod tip against the gun nozzle - follow the burner Manual.
5.5 Check the correctness of connections of igniter’s components and protective grounding of the igniter rod
and power pack enclosure as well as circuit grounding. Powering the rod outside a burner should only be
done to test its operation.
5.6 The igniter supply should have effective grounding. Correct connection of the grounding of the igniter
should be checked first, then the line can be connected.
5.7 Do not touch, lift, carry the igniter rod or power pack when the igniter is energized or is not disconnected
from a potential source of electrical power.
5.8 Once assembled, the igniter can undergo the functional test. The rod should be positioned clear of
equipment, flammable materials and personnel. If these conditions are met, power can be applied, and device
switched on.
5.9 Do not open the power pack enclosure, disconnect rod tip or HV cable and grounding cables when the
equipment is energized or is not disconnected from potential source of electrical power supply.
5.10 Never use water to wash igniter components when it is connected to source of electrical power.
IGNITER START-UP AND OPERATION:
5.11 During the burner start-up the main voltage 230/115 VAC can be applied to the power pack, provided that
proper wiring conditions as in p. 5.3 to 5.6 have been verified, as well as the correct assembly of the igniter
has been inspected.
5.12 When starting the burner installation from cold conditions after a longer standstill, check the operation of
the ignition device itself without opening the fuel flow to the burner. When power applied:
- check that the retraction system functions correctly: whether the rod tip reaches its working point when is
inserted, and after retraction completely hides in guide tube away from flame zone.
- check if the rod movement is smooth without jams and obstructions, and safe for the operator. Adjust air
valves if necessary. Follow the retraction system instructions in SF-2001 High Energy Igniter bulletin,
- check the presence and repeatability of electrical sparks on the rod tip,
- no other sparking should be visible on rod connections, grounding points and cable glands. Should that be
the case, de-energize igniter immediately and follow the p. 7 instructions.
- in the case of no sparks present at the rod tip during energizing please refer to p. 7.
5.13 If, after above checking, sparks are strong and repeatable a full burner test with fuel can be performed. If
the spark is present but the igniter does not light the fuel, check fuel settings and the presence of fuel at the
nozzle. If the fuel settings are within the recommended range and during the Trial for Ignition the fuel is
present at the burner nozzle the rod position should be adjusted to ensure that the rod tip is in the correct
location. After moving the rod in new position, the test of ignition should be repeated.
5.14 If the flame is present, rod tip is in proper position, but there is no flame confirmation refer to p. 7.
5.15 The igniter’s use for direct ignition of oil fuel may take place only if sufficiently high atomization medium
(steam, air) and oil temperature as well as their proper pressure can be maintained.
5.16 It is recommended to ignite the burner at a low fuel flow and with a limited quantity of combustion air.
It is further recommended to use shut-off valves with a slow opening and fast closing capability.
