Abstract

Liquid is delivered into a void between a burner and a melt vessel, which causes a skull of a material to form within an interior of the melt vessel. The void is in fluidic communication with the interior of the melt vessel. The burner is moved from a first position internal to the void to a second position external from the void. Thereafter, the burner is isolated from the void.

First claim

What is claimed is:

1. A method of removing a burner having a plurality of hoses from a melt vessel, the method comprising:
delivering a liquid into an annular void defined on an inner side by an outer wall of the burner and on an outer side by a floor of the melt vessel, wherein delivery of the liquid into the annular void forms a skull of a material disposed within an interior of the melt vessel, wherein the annular void is in fluidic communication with the interior of the melt vessel, and wherein the annular void defines an annular, volume when the burner is in a first position, wherein when in the first position, at least a portion of the burner is disposed below an outer wall of the melt vessel, and wherein the liquid is delivered to the annular void from an inlet external to the burner;
disposing a cooling vessel around the portion of the burner disposed below the outer wall of the melt vessel, wherein the cooling vessel defines an opening that the plurality of hoses pass through;
moving the burner from the first position to a second position external from the annular void and within the cooling vessel; and
once the burner is in the second position, isolating the burner from the annular void.

2. The method of claim 1 , further comprising fixing a position of the cooling vessel relative to the melt vessel.

3. The method of claim 2 , wherein when the burner is in the second position, the burner is disposed distal from the melt vessel.

4. The method of claim 2 , wherein the burner occupies a first volume of the cooling vessel when the burner is in the first position and wherein the burner occupies a second volume of the cooling vessel when the burner is in the second position, wherein the second volume is greater than the first volume.

5. The method of claim 2 , further comprising unfixing the position of the cooling vessel relative to the melt vessel, once the burner is in the second position.

6. The method of claim 1 , wherein isolating the burner comprises closing a valve disposed between the burner and the void when the burner is in the second position.

7. The method of claim 1 , further comprising interrupting a fuel flow to the burner, prior to moving the burner to the second position.

8. The method of claim 1 , wherein the melt vessel is utilized in a submerged combustion melting (“SCM”) melter system.
