Abstract:
A cupola emission control system comprisinga cupola having a charge holding area,main afterburners located above said charge holding area of said cupola,an orifice ring in said cupola above said main afterburners,pilot burners in said cupola above said orifice ring,a quenching device connected to draw high temperature combusted air from said cupola above said pilot burners and to lower the temperature of such air by impinging a water spray onto such air as it passes through said quenching device,at least one venturi device connected to draw air from said quenching device,at least one main draw fan connected to draw air from said cupola and through said quenching device and through said venturi device,wherein said orifice ring restricts the diameter of said cupola above said pilot burners,and said venturi device controls the amount of air drawn into said cupola thereby controlling the combustion temperature above said orifice ring,a water separator device connected to receive air from said venturi device,said water separator device comprising a structure having two internal layers of packing each comprising numerous multi-surfaced structures,a first of said two internal layers of packing offering surface area of said numerous multi-surfaced structures sufficient to cause a majority of water in said air from said venturi device to be removed from air passing through said water separator device,and a second of said two internal layers of packing offering surface area of said numerous multi-surfaced structures sufficient to reduce the temperature of said air from said venturi device.
