A multi-deck burner assembly for a conveyor-type oven can include a central manifold feeding fuel to upstream and downstream arrays of burners. Other burner assemblies can include pilot burners disposed at approximately a midway point along a longitudinal direction of the burners, thereby enabling the use of longer burners, and thus more efficient burner assembly design. Some burner assemblies can include both a centrally located manifold feeding upstream and downstream arrays and pilot burners disposed at approximately midpoints along the longitudinal lengths of both the upstream and downstream arrays.

A galvanizing furnace (1) with a galvanizing vat (6) and a furnace housing (2) surrounding the galvanizing vat (6), which furnace housing has a rectangular cross-section. The furnace housing (2) has two opposite longitudinal sidewalls (4) and two opposite end walls (5) and further comprises burners for heating molten zinc in the galvanizing vat (6). In the areas of two diagonally opposite corners of the furnace housing (2), at least one first receptacle (15) is provided for a burner. In the areas of the other two diagonally opposite corners of the furnace housing (2), a second receptacle (16) is provided for a burner. The burners are arranged optionally either in the first receptacles (15) or in the second receptacles (16). Flames produced by the burners are conducted in the area between a longitudinal sidewall (4) of the furnace housing (2) and the opposite wall of the galvanizing vat (6).
