Abstract
A burner is configured for attachment along a wall of a furnace of a melter and includes a fuel conduit and a coolant shell. The fuel conduit extends from a supply end to a combustion end, and the coolant shell surrounds the combustion end of the fuel conduit. The burner is configured to receive a cooling fluid and circulate the cooling fluid within the cooling shell before the cooling fluid exits the burner. The coolant shell is removable and replaceable with another identical coolant shell.
Claims24
A burner configured for attachment along a wall of a melting chamber of a melter, the burner comprising:
- a rearward section comprising
- a mounting flange configured for mounting the burner to the wall of the melting chamber,
- a gas conduit, and
- an axially extending partition;
- and
- a forward section sealingly and removably coupled to the mounting flange of the rearward section and comprising a coolant shell, the coolant shell comprising
- an outer wall spaced radially outwardly from the partition of the rearward section to establish a radially outer portion of a coolant passage between the partition and the outer wall, and
- an inner wall spaced radially inwardly from the partition of the rearward section to establish a radially inner portion of the coolant passage between the partition and the inner wall.
A burner configured for attachment along a wall of a furnace of a melter, the burner comprising:
- a rearward section configured for mounting the burner to the furnace and comprising a fuel conduit extending from a supply end to a combustion end;
- a forward section comprising a burner tip, the forward section being removably attached to the rearward section and surrounding the combustion end of the fuel conduit;
- and
- an elastomeric seal at an interface between the rearward section and the forward section, the elastomeric seal being axially spaced from the burner tip and releasable from at least one of the forward section or the rearward section when the forward section is removed from the rearward section,
- the forward section further comprising a radially inner wall and a radially outer wall, wherein the interface between the rearward section and the forward section is located along the radially inner wall, and wherein the elastomeric seal is radially compressed at the interface.
A submerged combustion melting burner, comprising:
- a rearward section including
- a mounting flange,
- a coolant shell partition extending in a forward direction with respect to the mounting flange, and
- a gas conduit;
- and
- a forward section removably and replaceably coupled to the rearward section, the forward section including
- an attachment flange sealingly and removably coupled to the mounting flange of the rearward section, and
- a coolant shell coupled to the attachment flange, the coolant shell including
- an outer wall extending in the forward direction from the attachment flange and spaced radially outwardly of the coolant shell partition of the rearward section to establish a coolant inlet path between the coolant shell partition and the outer wall,
- an end wall terminating the outer wall at an end of the burner and spaced axially from the coolant shell partition to establish a coolant transition path between the cooling shell partition and the end wall, and
- an inner wall extending from the end wall in a rearward direction and sealingly and removably coupled to the gas conduit of the rearward section, the inner wall being spaced radially inwardly of the cooling shell partition of the rearward section to establish a coolant outlet path between the cooling shell partition and the inner wall.
