ABSTRACT:
For use in a combustion furnace for analytical apparatus in which a specimen is combusted in a combustion chamber and gases therefrom are withdrawn for analysis, a cleaning apparatus mounted at one end of the combustion chamber. The cleaning apparatus includes a housing sealably mounted to the combustion chamber and containing a movable cleaning element for abrading the interior walls of the combustion chamber. A shield is positioned between the cleaning element and the combustion chamber such that during combustion of a specimen, the cleaning element is effectively shielded from the high temperature combustion. In one embodiment, the housing also includes a filter between gas supply and exhaust passages and apparatus for self-cleaning of the filter.
