Abstract
A premixed gas burner has an elongated hollow burner body including a burner deck formed by a multiplicity of burner ports about a small sector of the body. The burner body is closed at one end and an elongated distribution tube is received within the body through and extending out the other end. The end of the distribution tube extending out of the burner body has an inlet into which a mixture of gas and air may enter, the opposite end of the distribution tube being closed. A series of directional ports formed between louvered slats adjacent the closed end and spaced from the inlet are formed along a small sector of the distribution tube and directs the mixture of gas and air back toward the inlet end. The sector of the distribution tube in which the ports are formed is substantially 180.degree. from the sector of the burner body in which the deck ports are formed. The construction provides good mixing, and substantially prevents flashback by having high velocity throughout the burner, and good distribution without a high pressure drop.
