Abstract

An apparatus for cleaning a continuous emissions monitor system that is in fluid communication with a flue stack conducting exhaust gas from a combustion source. The apparatus comprises a housing and a probe mounted in the housing. The probe is tubular and in fluid communication with the flue stack to acquire a sample of gas from the flue stack. The probe tends to have deposits from the exhaust gas accumulate on the inner walls of the probe. A device imparts cleaning energy to the probe for dislodging accumulated deposits from the inner walls of the probe.
