Abstract:
A high temperature flow element comprising:a mounting extension comprising a tubular housing having a head end opposite a mounting end forming a hollow interior cavity there between;an element head having a first instrument port in fluid communication with a first cleaning port and a first element connection port and a second instrument port in fluid communication with a second cleaning port and a second element connection port, said element head connected to said head end such that said first and second element connection ports are in fluid connectivity with said hollow interior cavity;a first flow element tube having a first proximal end opposite a first distal end, said first proximal end attached to said first element connection port, said first flow element passing through said hollow interior cavity and exiting through said mounting end;a second flow element tube having a second proximal end opposite a second distal end, said second proximal end attached to said second element connection port, said second flow element passing through said hollow interior cavity and exiting through said mounting end; andan outboard support comprising an outboard support plate supporting at least one outboard support fitting, said outboard support fitting further comprising a modified compression fitting that secures said first and second distal ends, forming a tight, reliable seal while permitting longitudinal thermal expansion of said first and second flow element tubes;a gas flow duct having a high temperature flow element affixed thereto, passing through a first insertion aperture in the duct sidewall, traversing the interior of said gas flow duct and exiting through a second insertion aperture in the opposing duct sidewall, said mounting end affixed to the exterior surface of said gas flow duct at said first insertion aperture and said outboard support plate affixed to the exterior surface of said gas flow duct at said second insertion aperture, said mounting extension positioning said element head in an offset manner so as to provide access free from obstruction by duct insulating materials, said outboard support fitting allowing for a longitudinal thermal expansion of said first and second element tubes.
