APPLICATIONS

High Energy Spark Igniters ( HESI ) are well suited to ignite most gaseous and liquid fuels, either by
first igniting a pilot or directly igniting the main burner.

The HESI is classified as being a class 3 special igniter (NFPA regulations).

Burner designers should ensure the correct position of the igniter tip, and the maximum capacity of
flame to be ignited to ensure compliance with prevailing regulations.

Typical applications

- Petro chemical, and refineries, (frequently ATEX style).

- Heaters, Reformers. Metal industries, Kilns.

- Power burners, Steam raising plants.

- Direct, and pilot ignition. Paper industry

- Black liquor boilers
