Abstract
A discharge housing for connection to a plasma arc furnace outlet, having water quenching stations positioned inside the housing into the gas flow path, and having an inner flow path concentrically positioned inside an outer flow path, with an exhaust port on the downstream end of the outer flow path.
Claims9
An apparatus for controlling the exhaust gases from a plasma arc furnace, comprising a housing attachable to the outlet from said furnace, said housing having an initial insulated portion with at least one spray quenching station for delivering cooling spray into the exhaust gases, and having an open downstream end, said housing having an outer passageway concentrically fitted over said inner passageway, having an upstream end in gas flow communication with the downstream end of said inner passageway, with an end cap for deflecting the exhaust gases into a reverse direction, and having a downstream end, said outer passageway having at least one spray quenching station for delivering cooling spray into the exhaust gases, and an exhaust fitting proximate the downstream end of said outer passageway.
A plasma arc furnace cooling and discharge housing, comprising:
- a) an elongated tube having a flange adapted for connection to a plasma arc furnace discharge port, and having an open downstream end;
- b) an insulating inner liner concentrically fitted into said elongated tube;
- c) an outer housing cover concentrically fitted over said elongated tube, and sized to provide a flow path therebetween and to deflect the flow path into a reverse direction relative to the flow path inside the elongated tube;
- and
- d) an exhaust port in said outer housing cover.
