Burner assembly and system for heating drying air

摘要

A burner assembly includes a blower assembly couplable to a source of fuel, and a longitudinally elongated housing having a lateral upstream edge, a lateral downstream edge, and a slot formed in the downstream edge. The housing encloses a combustion chamber comprising a generalized cylinder with cross-section having an arcuate portion and a straight portion, the arcuate portion defined by the lateral upstream and downstream edges of the housing. The burner assembly also includes an elongated burner head assembly, the elongated burner head assembly having a first end coupled to the blower and a second end disposed within the combustion chamber.

1. A burner assembly comprising:
a blower assembly couplable to a source of fuel; a longitudinally elongated housing having a first lateral edge, a second, opposite lateral edge, and a slot formed in the second edge, the housing with a wall enclosing a combustion chamber, the chamber having a constant cross-section taken normal to the longitudinal direction, the cross-section having an arcuate portion defined along a circle and a straight portion defined along a chord of the circle, the arcuate portion defined by the first and second lateral edges of the housing wall and the straight portion defined by the housing wall disposed between the first and second edges, the slot being disposed at a right angle to the straight portion as viewed along the longitudinal direction; and a longitudinal elongated burner head assembly, the elongated burner head assembly having a first end coupled to the blower assembly, a second end longitudinally-spaced from the first end, disposed within the combustion chamber and spaced from the housing, and a circular cylindrical shape between the first and second ends, the elongated housing has a longitudinal axis and the elongated burner head assembly has a longitudinal axis, the elongated burner head assembly disposed within the elongated housing with the longitudinal axes of the housing and the burner head assembly collinear with each other.
