Insulated electrodes are used in two forms, as igniter 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 water, gas turbines, domestic gas cookers, etc.
Igniting electrodes atre 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, where custom made small/large quantity high tension igniting electrodes for domestic and industrial use can be developed and manufactured to international quality standards.
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.
We welcome customer enquiries for standard/custom-designed igniting electrodes.
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 across the gap is sufficient to ignite distillate medium fuel oils and most gas installations. In some installations a single electrode 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 available in 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 Dai 6 to 15mm x 50 to 550mm length
