IGNITION

**Definition:** This place covers:

Apparatus or methods specially adapted for providing the heat, spark or flame required to start combustion of a fuel. Such apparatus can itself be a combustion apparatus (e.g. a cigarette lighter or a pilot flame) that is provided with ignition arrangements of its own.

Mechanical igniters.

Lighter containing fuel e.g. for cigarettes.

Igniters using electrically-produced sparks.

Make-and break ignition.

Incandescent ignition.

Pilot flame igniters.

Arrangement of catalytic igniters.

Devices for effecting ignition from a remote location that is remote from the combustion apparatus to be ignited, e.g. for combustion apparatus that is difficult or dangerous to access.

Testing of ignition installations.

Extinguishing-devices, e.g. for blowing-out or snuffing candle flames.

**Glossary:** - Retention flame: A small flame that is kept alight in order to maintain the uninterrupted operation of a more powerful burner. - Pilot flame: A small flame that is lit or kept alight in order to provide ignition to a more powerful burner. - Fire lighter: An element that either consists of combustible material or absorbs liquid fuel, and is intended for use in a fire-place or the like for simplifying the ignition of solid fuel.
