Abstract
A burner and/or injector panel includes at least two cooling circuits that may be connected in series with a flexible hose or rigid pipe connected to the circuits behind a rear face of the panel or connected in parallel to a source of cooling water by independently connecting each cooling circuit to the cooling water source without connecting the flexible hose or rigid pipe.
Claims7
A water cooled burner and/or injector panel kit for use in a melting furnace to cool a burner and/or an injector, comprising:
- a panel having first and second cooling water circuits and at least one orifice for mounting a burner and/or an injector, the panel also having a back face, a front face, a top face, a right face, and a bottom face, the first cooling circuit extending through an interior of the panel between an associated inlet and an associated outlet each of which projects out of the back face, the second cooling circuit also extending through an interior of the panel between an associated inlet and an associated outlet each of which projects out of the back face;
- and
- a removable flexible hose or rigid pipe adapted and configured to be reversibly connected to the outlet of the first circuit and to the inlet of the second circuit to allow water to flow, in order, into an inlet of the first circuit, through the first circuit, the removable hose or pipe, and the second circuit, and out of an outlet of the second circuit without leaking.
A water cooled burner and/or injector panel apparatus kit for use in a melting furnace, comprising:
- a panel having first and second cooling water circuits and at least one orifice for mounting a burner and/or an injector, the panel also having a back face, a front face, a top face, a right face, and a bottom face, the first cooling circuit extending through an interior of the panel between an associated inlet and an associated outlet each of which projects out of the back face, the second cooling circuit also extending through an interior of the panel between an associated inlet and an associated outlet each of which projects out of the back face;
- a burner and/or injector inserted in the at least one orifice;
- and
- a removable flexible hose or rigid pipe adapted and configured to be reversibly connected to the outlet of the first circuit and to the inlet of the second circuit to allow water to flow, in order, into an inlet of the first circuit, through the first circuit, the removable pipe, and the second circuit, and out of an outlet of the second circuit without leaking.
A method of cooling a burner and/or injector panel apparatus kit that is mounted on a side wall of an EAF or on a balcony panel of an EAF, the burner and/or injector panel apparatus kit comprising:
- a panel having first and second cooling water circuits and at least one orifice for mounting a burner and/or an injector, the panel also having a back face, a front face, a top face, a right face, and a bottom face, the first cooling circuit extending through an interior of the panel between an associated inlet and an associated outlet each of which projects out of the back face, the second cooling circuit also extending through an interior of the panel between an associated inlet and an associated outlet each of which projects out of the back face;
- a burner and/or injector inserted in the at least one orifice;
- and
- a removable flexible hose or rigid pipe adapted and configured to be reversibly connected to the outlet of the first circuit and to the inlet of the second circuit to allow water to flow, in order, into an inlet of the first circuit, through the first circuit, the removable pipe, and the second circuit, and out of an outlet of the second circuit without leaking, wherein said method comprises the steps of:
- connecting the first and second circuits in series to a source of cooling water by connecting the inlet or outlet of one of the two circuits to the inlet or outlet of the other of the two circuits with the flexible hose or rigid pipe;
- and
- disconnecting the flexible hose or rigid pipe and connecting the first and second circuits in parallel to a source of cooling water without connecting the two circuits with the flexible hose or rigid pipe.
