Abstract
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.
