Tubular-Flat High Tension Single-Twin Igniting Electrodes

Insulated
electrodes are used in two forms, as igniters and flame detecting probes. Electrode consists basically
of corrosion and spark erosion resistant alloy conductor encapsulated in a high quality glazed-unglazed
alumina-steatite ceramic insulators.
The
electrodes can be supplied with a gland nut or by screwing to the casing or with sheet metal brackets
for fixing with screws. Igniting electrodes are used for igniting of gas and medium distillate fuel oil
burners used for industrial boilers and domestic wate, gas turbines, domestic gas cookers, etc.
Igniting
electrodes are available in wide range of sizes to meet individual requirements.
Thanks
to Jyoti's modern ceramic manufacturing facilities coupled with state-of-the-art R&D Lab and
CAD-CAM assisted tool room cum engineering workshop, custom made small/large quantity high tension igniting
electrodes for domestic and industrial use can be developed and manufactured to international quality
standards.

We welcome
customer enquiries for standard/custom-designed igniting electrodes.
Regular
igniting electrodes are available with Kanthal-D/equivalent wire conductor. Igniting electrodes can also be
availed with Kanthal A-1/ stainless or other alloy steel conductors. Prices on request.
Following
are the standards for electrode conductors used in igniters :
Kanthal
-D Electrode suitable for operating temperature 1300°C or equivalent.
Kanthal
A-1 Electrode suitable for operating temperature 1400°C or equivalent.
STAINLESS
STEEL Electrode grade 404 suitable for operating temperature 700°C or equivalent.

The
simplest type of electric ignition is the high tension system, which usually takes the form of a mains
transformer supplying some 10K volts to a pair of insulated electrodes placed to form a spark gap adjacent
to the burner nozzle. The resultant spark acroos the gap is sufficient to ignite distillate medium fuel
oils and most gas installations. In some installations a single elctrode may be mounted to utilize a part
of the burner casing (or a special projection from it) to complete the circuit.

The growing
use of various gases and oils as a burning fuel for both industrial and domestic boilers has led to development
of equipment to control the burner under varying load conditions. During periods when no load is imposed on
the boiler, the boiler is allowed to shut down, conversely when it is necessary to relight the burner the control
gear switches on the ignition system again.
Ceramic
insulators used in manufacture of igniters are availablein low-loss, alkali-free glazed/unglazed natural smooth
surface finish steatite and 92-95% white/pink Aluminium Oxide glazed or unglazed in natural satin smooth surface-finish,
as per the customer's choice.
Tubular
ceramic insulators are available in Dia. 6 to 15mm x 50 to 550mm length.
Ceramic
insulators used in manufacture of igniting electrodes are of high grade quality materials of following specifications
