Abstract

Theappts. comprises a housing, a flame outlet, and a carrier gas feed pipe for the flame outlet. A compressed air pipe opens into the interior of the housing, and a piece of salt having a longitudinal bore is arranged above the flame outlet. A collector ring mounted above the flame outlet has first and second electrical connections, the latter absorbing the flame potential. An indicator is mounted in the flow circuits between the two connections.
