Abstract: A deep fat fryer burner tube insert for improving heat transfer and efficiency. The insert is stamped and formed from thin stainless steel having a length and a width that substantially equals the length and long dimension the oval cross section of a burner tube, respectively. Pairs of triangular-shaped fins are cut and oppositely bent outwardly perpendicular to the plane of the sheet for disrupting the laminar flow of combustion products through the burner tube. The number of triangular-shaped fins and their shape is selected to accommodate the needs of combustion efficiency and exhaust pollutant minimization. Right triangle-shaped fins having angles of 45° and 60° have been found effictive for use with burner tubes of 14 inch and 18 inch lengths, respectively.

Abstract: A fry pot includes a burner tube that is secured to the walls of the fry pot with front and rear end welds. A front end weld shield consists of a stainless steel clad first molded ceramic positioned between the gas burner and the front of the burner tube and a rear end weld shield consists of a second molded ceramic having a brim shaped portion positioned in the rear of the burner tube. Both end weld shields have grooves within which the respective end welds are received.
