Abstract
An apparatus for supplying gas to a determinate number of injector devices of a melting furnace for the production of metal, including a main feed line, a first secondary feed line and a second secondary feed line which are respectively configured to supply, selectively and in a controlled manner, a process gas, an inert gas and a purge gas to each of the injector devices.
Claims12
An apparatus for supplying gas to a melting furnace for the production of metal, wherein said melting furnace has a plurality of a determinate number of injector devices, wherein said apparatus comprises:
- first supply means configured to selectively supply a process gas to said injector devices;
- second supply means configured to selectively supply an inert gas to said injector devices;
- third supply means configured to selectively supply a purge gas to said injector devices;
- a main feed line fluidically connected to said first supply means and configured to selectively supply said process gas to each of said injector devices, after a first branch, in correspondence with a first branch point, into a number of peripheral main feed lines equal to said determinate number;
- said apparatus further comprising
- a first secondary feed line fluidically connected to said second supply means and configured to selectively supply said inert gas to each of said injector devices, after a second branch, in correspondence with a second branch point, into a number of first peripheral secondary feed lines equal to said determinate number;
- a second secondary feed line fluidically connected to said third supply means and configured to selectively supply said purge gas to each of said injector devices, after a third branch, in correspondence with a third branch point, into a number of second peripheral secondary feed lines equal to said determinate number;
- a same determinate number of connection points, each of which is disposed downstream of said branches and upstream of each of said injector devices and in which one of said peripheral main feed lines, as well as one of said first peripheral secondary feed lines and also one of said second peripheral secondary feed lines converge;
- a same determinate number of terminal segments each of which fluidically connects one of said connection points to one of said injector devices;
- a same determinate number of regulation units each disposed on one of said terminal segment and configured to regulate the flow rate of the one gas amongst said process gas, inert gas and purge gas that is temporarily conveyed toward one of said injector devices.

A method for supplying gas to a melting furnace for the production of metal, wherein said melting furnace has a plurality of a determinate number of injector devices, comprising the following steps:
- providing first supply means to selectively supply a process gas to said injector devices through a main feed line;
- providing second supply means to selectively supply an inert gas to said injector devices through a first secondary feed line
- providing third supply means to selectively supply a purge gas to said injector devices through a second secondary feed line,
- a main feed step, in which said first supply means selectively supply said process gas to each of said injector devices through said main feed line, after a first branch, in correspondence with a first branch point, into a number of peripheral main feed lines equal to said determinate number;
- said method further comprising:
- a first secondary feed step, in which said second supply means selectively supply said inert gas to each of said injector devices through said first secondary feed line, after a second branch, in correspondence with a second branch point, into a number of first peripheral secondary feed lines equal to said determinate number;
- a second secondary feed step, in which said third supply means selectively supply said purge gas to each of said injector devices through said second secondary feed line, after a third branch, in correspondence with a third branch point, into a number of second peripheral secondary feed lines equal to said determinate number;
- wherein there is provided a determinate number of connection points, each of which is disposed downstream of said branches and upstream of each of said injector devices, and in which one of said peripheral main feed lines, as well as one of said first peripheral secondary feed lines and also one of said second peripheral secondary feed lines converge;
- wherein there is also provided a same determinate number of terminal segment, each of which fluidically connects one of said connection points to one of said injector devices;
- and
- wherein in each of said three feed steps the flow rate of each of said process gas, inert gas and purge gas is selectively regulated by means of a same determinate number of regulation units, each disposed on a respective one of said terminal segments.
