Multi-chamber submerged combustion melter and system
A submerged combustion melter includes first, second, third, and fourth side walls extending upwardly from a bottom wall, a crown extending inwardly with respect to the side walls and over the bottom wall to establish a melting chamber, an exhaust port configured to exhaust gas from the melting chamber, a baffle coupled to and extending inwardly from the third side wall to divide the melting chamber into melting sub-chambers that share the exhaust port and having an end spaced away from the fourth side wall, an inlet configured for introducing a glass batch into the melter, and an outlet configured to remove molten glass from the melting sub-chambers, which direct product flow in a laterally undulating flow path from the inlet to the outlet.
1. A submerged combustion melter, comprising:
a bottom wall;
at least one side wall extending upwardly from the bottom wall and including a first side wall, a second side wall, a third side wall, and a fourth side wall;
a longitudinal axis extending from the first side wall to the second side wall;
a laterally transverse axis extending from the third side wall to the fourth side wall;
a crown extending inwardly with respect to the at least one side wall and over the bottom wall to establish a melting chamber;
an exhaust port configured to exhaust gas from the melting chamber;
a baffle coupled to and extending inwardly from the third side wall to divide the melting chamber into at least two melting sub-chambers that share the exhaust port, and having an end spaced away from the fourth side wall;
at least one inlet configured for introducing a glass batch to the submerged combustion melter;
at least one outlet configured to remove molten glass from the at least two melting sub-chambers; and
wherein the at least two melting sub-chambers are configured to direct product flow from the inlet, around the end of the baffle between the end of the baffle and the fourth side wall, and to the at least one outlet.
2. The submerged combustion melter of claim 1 , wherein at least one of the bottom wall, the at least one side wall, or the crown is fluid-cooled.
3. The submerged combustion melter of claim 1 , wherein at least one of the bottom wall, the at least one side wall, or the crown is non-fluid-cooled.
4. The submerged combustion melter of claim 1 , wherein the baffle is a non-fluid-cooled baffle.
5. The submerged combustion melter of claim 4 , wherein the non-fluid-cooled baffle includes a refractory material.
6. The submerged combustion melter of claim 1 , wherein the baffle is a fluid-cooled baffle.
7. The submerged combustion melter of claim 6 , wherein the fluid-cooled baffle is configured to receive cooling fluid from the third side wall.
8. The submerged combustion melter of claim 1 , wherein combustion gases from all the melting sub-chambers collect in one exhaust chamber and exhaust from the exhaust port.
9. The submerged combustion melter of claim 1 , further comprising a second baffle coupled to the fourth side wall, wherein the baffle and the second baffle are in a staggered configuration, and wherein the second baffle has an end spaced away from the third side wall.
10. The submerged combustion melter of claim 9 , further comprising a third baffle coupled to the third side wall, wherein the baffle and the third baffle are staggered from the second baffle and the second baffle is disposed between the baffle and the third baffle, and wherein the third baffle has an end spaced away from the fourth side wall.
11. The submerged combustion melter of claim 1 , wherein the baffle is disconnected from the crown.
12. The submerged combustion melter of claim 1 , wherein the baffle is removable from the third side wall.
13. The submerged combustion melter of claim 1 , wherein an angle of the baffle is adjustable.
14. The submerged combustion melter of claim 1 , wherein the baffle is coupled to the bottom wall and the third side wall.
15. A submerged combustion melter, comprising:
a bottom wall;
a plurality of side walls including a first side wall, a second side wall, a third side wall, and a fourth side wall extending upwardly from the bottom wall;
a longitudinal axis extending from the first side wall to the second side wall;
a laterally transverse axis extending from the third side wall to the fourth side wall, the laterally transverse axis perpendicular to the longitudinal axis;
a crown extending inwardly with respect to the plurality of side walls and over the bottom wall to establish a melting chamber;
an exhaust port configured to exhaust gas from the melting chamber;
a baffle disconnected from the crown, coupled to and extending inwardly from the third side wall to divide the melting chamber into at least two melting sub-chambers that share the exhaust port, and having an end spaced away from the fourth side wall;
an inlet configured for introducing a glass batch to the submerged combustion melter;
an outlet configured to remove molten glass from the at least two melting sub-chambers; and
wherein the at least two melting sub-chambers are configured to direct product flow in an undulating flow path between the inlet and the outlet and between the end of the baffle and the fourth side wall.
16. The submerged combustion melter of claim 15 , further comprising a second baffle downstream of the baffle and extending inwardly from the fourth side wall and having an end spaced away from the third side wall, wherein the baffle and the second baffle are in a staggered configuration.
17. The submerged combustion melter of claim 16 , further comprising a third baffle downstream of the second baffle and extending inwardly from the third side wall and having an end spaced away from the fourth side wall, wherein the second baffle and the third baffle are in a staggered configuration.
