Submerged combustion burners having improved fuel and oxidant mixing characteristics. Submerged combustion melters including the burners. Methods of using submerged combustion melters to melt glass-forming materials and produce molten glass.

Submerged combustion burners, submerged combustion glass melters including the burners, and methods of use

Submerged combustion burners having a burner body and a burner tip body connected thereto. The burner body has an external conduit and a first internal conduit substantially concentric therewith. The external conduit and first internal conduit form an annulus for passing a cooling fluid there between. A second internal conduit substantially concentric with the external conduit forms a second annulus between the first and second internal conduits. A burner tip body is connected to the burner body at ends of the external and first internal conduits. The burner tip body includes a generally central flow passage for a combustible mixture, the flow passage defined by an inner wall of the burner tip body. The burner tip body further has an outer wall and a crown connecting the inner and outer walls. The crown includes at least one physical convolution sufficient to increase surface area and fatigue resistance of the crown.

Burner for submerged combustion melting

A transport vehicle spray apparatus. The transport vehicle spray apparatus has at least one storage tank. A pump transports material from the storage tank through at least one filter and a manifold to at least one spray bar. The spray bar incorporates spray nozzles through which the material from the storage tank is dispensed. In one embodiment, the spray bar is connected to a collapsible frame on the top and back of the transport vehicle storage space. The collapsible frame can expand and collapse by sliding along the length of the walls of the transport vehicle storage space. As the frame expands and collapses, the spray bar coats the interior surfaces of the transport vehicle storage space with the material from the storage tank. The transport vehicle spray apparatus is utilized to spray and coat the walls of a transport vehicle's storage space with a desired fluid.

Transport vehicle spray apparatus

Combustion burner panels, submerged combustion melters including one or more of the panels, and methods of using the same are disclosed. In certain embodiments, the burner panel includes a panel body having a first major surface defined by a lower fluid-cooled portion of the panel body, and a second major surface defined by an upper non-fluid cooled portion of the panel body. The panel body has at least one through passage extending from the first to the second major surface, the through passages accommodating a set of substantially concentric inner and outer conduits. The inner conduit forms a primary passage for fuel or oxidant, and the outer conduit forms a secondary passage between the outer conduit and the inner conduit for fuel or oxidant. A protective member is associated with each set. The burner panels promote burner life and melter campaign length.

Burner panels including dry-tip burners, submerged combustion melters, and methods

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.

Change-out system for submerged combustion melting burner

Combustion burner panels, submerged combustion melters including one or more of the panels, and methods of making the same are disclosed. In certain embodiments, the burner panel includes a panel body having first and second major surfaces, at least one oxidant through-passage extending from the first to the second major surface, and at least one fuel through-passage extending from the first to the second major surface. Oxidant and fuel delivery conduits are positioned in the respective passages. The oxidant and fuel delivery conduits include proximal and distal ends, at least some of the distal ends positioned away from the first major surface of the panel body. In other embodiments the burner panels include a frame enclosing a porous material having through passages for fuel and oxidant. The burner panels may enable delaying combustion in a submerged combustion melter, and therefore promote burner life and melter campaign length.

Burner panels, submerged combustion melters, and methods

A portion of a submerged combustion burner is disposed into a pressure vessel. The portion of the submerged combustion burner has a welded area that has a first microstructure defined by a first number of voids. The vessel is filled with an inert gas, pressurized, and heated. Pressurizing and heating operations are performed for a time and at a temperature and a pressure sufficient to produce a second microstructure in the welded area of the burner. The second microstructure is defined by a second number of voids less than the first number of voids.

Post-manufacturing processes for submerged combustion burner

A method of forming a rope material from a loose feed scrap includes a number of operations to mechanically bind the loose feed scrap. The feed scrap is collected. The feed scrap is twisted and compressed, operations that may be performed simultaneously. This twisted and compressed feed scrap, now in the form of a rope material, is then fed into a melter system.

Systems and methods for mechanically binding loose scrap

Primary inorganic feedstock material is introduced into the melting region of an SCM melter. The material is heated with a burner to form a turbulent melt matrix. The burner exit is disposed below the top surface of the turbulent melt matrix. A mixture of secondary inorganic material and organic material is introduced into the melting region below the top surface of the turbulent melt mixture. The mixture is heated with the burner to incorporate the secondary inorganic material into the turbulent melt matrix and combust at least some of the organic material to produce heat.

Processing organics and inorganics in a submerged combustion melter

Submerged combustion glass manufacturing systems and methods include a melter having a floor, a roof, a wall structure connecting the floor and roof, and one or more submerged combustion burners mounted in the floor, roof, and/or wall structure discharging combustion products including water vapor under a level of material being melted in the melter and create turbulent conditions in the material. The floor, roof, or wall structure may include fluid-cooled refractory material and an optional metallic external shell, or the metallic shell may include coolant passages. One or more conduits drain water condensed from the water vapor from regions of refractory material substantially saturated with the water, and/or from burner supports.
