ABSTRACT:
A stepped, perforated tray is provided for increasing the available gas-slurry contact area in a flue gas desulfurization chamber. The tray redirects the horizontal flow upwardly through the tray for increased surface area and contact time with slurry for removing SOxor other contaminants from a fossil fuel combustion flue gas before releasing the flue gas to the atmosphere. The tray is adaptable for use in vertical tower systems as well.
