A method and an installation (10) for removing slag allows both slag removal and metal recovery from slag (60) to be performed quickly and easily. The risk of slag fires is reduced.

A method (110) for removing a quantity of slag (24) from hot metal (6) in a ladle (2) during a process of metal purification such as steelmaking using an improved skimmer paddle (100) having a system of internal piping (60) that at one end is attached to a source of gas and at a second end terminates into one or more ports (64). The improved skimmer (100) is moved along a top surface (6a) of the hot metal, though the quantity of slag, and predetermined flows of gas are forced into the piping system and expelled through the port or ports (64) to move the quantity of slag out from the back of ladle to be skimmed into a slag pot (4) to remove undesired impurities from the hot metal.

A skimmer (100) for removing a slag layer (24) from hot metal (6) in a ladle (2) during a process of metal purification such as steelmaking. The improved skimmer (100) is a steel framework covered in reinforced refractory, having a system of internal piping (60) that at one end is attached to a source of gas and at a second end terminating at one or more ports (64). The improved skimmer (100) is attached to a boom for a prior art skimming machine. In use, the improved skimmer (100) is moved along a top surface (6a) of the hot metal, though the slag layer, and predetermined flows of gas are forced into the piping system and expelled through the port or ports to move the slag layer out from the back of ladle so it can be skimmed into a slag pot (4).

There is disclosed a furnace (10), a fluid feed component, a fluid reforming system, and a method of reforming a fluid (20). The furnace (10) comprises a vessel (12) that defines a chamber (14) for holding a body of liquid (16). A fluid inlet (18) is provided for introducing a fluid (20) into the chamber (14) below a level (22) of the body of liquid (16) to cause the fluid (20) to interact with the liquid (16) and to migrate therethrough towards an outlet (24) for discharging a product (26) of the interaction from the chamber (14). A liquid circulation passage (28) is implemented, having a weir (30) which is operatively located near the level of the body of liquid (16), and a port (34) which is located remote from the weir (30) and in fluid (20) communication with the fluid inlet (18) so as to enable the liquid (16) to flow over the weir (30) through the liquid circulation passage (28) and through the port (34).
