ABSTRACT:
Alkali metal detectors previously employed in coal gasification systems are not suitable for use in combustion gas streams because of the high temperatures involved. In the present invention, alkali metal detector elements are mounted on a heat resistant flange including at least one shielded electrical ceramic feed-through. This flange is cooled to ensure the nonconductivity of the ceramic insulation.
