The purge gas feeding means comprises a plurality of paths running from an outer perimeter of the purge gas feeding means to an inner surface, the inner surface comprising a purge gas outlet for outputting the purge gas into the abatement system; wherein a cross sectional area of the plurality of paths increases from the outer perimeter to the inner surface such that a pressure of the purge gas falls flowing along the paths drops.
