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.
Claims25
A burner configured for attachment along a wall of a melting chamber of a melter, the burner comprising:
- a fuel conduit extending from a supply end to a combustion end;
- and
- a coolant shell surrounding the combustion end of the fuel conduit, the burner being configured to receive a cooling fluid and circulate the cooling fluid within the coolant shell before the cooling fluid exits the burner,
- wherein the coolant shell is removable and replaceable with another identical coolant shell.
A burner configured for attachment along a wall of a furnace of a melter, the burner comprising:
- a main body configured for mounting the burner to the furnace;
- a fuel conduit extending from a supply end to a combustion end;
- a tubular body removably attached to the main body and surrounding the combustion end of the fuel conduit;
- and
- an elastomeric seal at an interface between the main body and the tubular body, the elastomeric seal being releasable from at least one of the tubular body or the main body when the tubular body is removed from the main body.
A submerged combustion melting burner, comprising:
- a rearward section including
- a mounting flange,
- a cooling 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 cooling shell partition of the rearward section to establish a coolant inlet path between the cooling shell partition and the outer wall,
- an end wall terminating the outer wall at an end of the burner and spaced axially from the cooling shell partition to establish a coolant transition path between the cooling shell partition and the outer 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.
