An inlet body is for a fluid injector for a turbomachine. The inlet body includes a casing and an inlet nozzle, housed inside the casing, that serves as a seat for a mobile sealing member. The inlet nozzle includes a central duct for the fluid and an annular rim surrounding the central duct. The annular rim includes a housing for a gasket. The housing is defined by a bottom wall, an opening opposite the bottom wall, and two opposite walls which each extend between the bottom wall and the opening. The walls are tilted towards each other in the direction of the opening.

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.

An inlet manifold includes a main inlet oriented along a first direction and a pilot inlet oriented along a second direction perpendicular to the first direction. A wye passage includes an inlet branch in fluid communication with the main inlet. The inlet manifold also includes a first main passage in fluid communication with a first outlet branch of the wye passage and a second main passage in fluid communication with a second outlet branch of the wye passage. The first main passage extends generally along the first direction between the wye passage and a first main outlet. The second main passage extends generally along the first direction between the wye passage and a second main outlet. The inlet manifold also includes a pilot passage in fluid communication with the pilot inlet. The pilot passage extends generally along the first direction between the pilot inlet and a pilot outlet.

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.
