Inlet assembly for an abatement assembly and method of conveying an effluent to an abatement chamber

An inlet assembly for an abatement apparatus, comprising:

• an effluent stream conduit configured to convey an effluent stream along a major direction of flow within said effluent stream conduit;
• an inlet nozzle fluidly coupled with said effluent stream conduit and configured to convey said effluent stream received from said effluent stream conduit to an abatement chamber of said abatement apparatus in an inlet direction;
• and
• a baffle interposed between said effluent stream conduit and said inlet nozzle, said baffle being shaped and configured to redirect flow of said effluent stream from said effluent stream conduit in a direction opposite the inlet direction and then into said inlet nozzle, wherein said baffle comprises a baffle conduit positioned within a plenum configured to receive said effluent stream from said effluent stream conduit, said baffle conduit defining at least one aperture positioned for fluid communication between said plenum and said inlet nozzle and wherein at least one of said baffle conduit and said inlet nozzle comprises coaxial lance positioned therewithin.
