Abstract
The gas tube fryer comprises substantially 90° in-shot burners, burner mounting boxes, a one-piece burner mounting bracket, and a bracket housing, all of which are used in conjunction with heat exchanger tubes, heat transfer baffles, a frypot, and a flue in a fryer. The burner mounting boxes are keyed specifically to the face of the burner, preventing substantial movement of the burners and introduction of ambient air into the heat exchange tubes. Each burner is also keyed to the mounting bracket, also preventing substantial movement and providing easy installation and repair. The ninety-degree orientation of the burners facilitates mixing of the combustion gases, and the burner comprises a screen on its face that helps to ensure maximum burner efficiency.
Claims9
A fryer assembly, comprising:
- a frypot;
- at least one heat exchanger tube, wherein said heat exchanger tube is disposed within said frypot;
- at least one burner comprising a top opening and a bottom opening;
- at least one burner mounting box,
- a keyed burner mounting bracket, and
- a gas manifold,
- wherein said keyed burner mounting bracket and said burner mounting box align said burner to said heat exchanger tube, to prevent the passage of a significant amount of ambient air therethrough, and so that there is no substantial movement of said burner,
- wherein when the fryer assembly is in use, a mixture of gas and air exits said gas manifold, enters said bottom opening of said burner, travels in an upward direction, and exits at said top opening of said burner.
A method for heating oil in a frypot of a fryer assembly, wherein said fryer assembly comprises:
- said frypot;
- at least one heat exchanger tube, wherein said heat exchanger tube is disposed within said frypot;
- at least one burner;
- at least one burner mounting box, and
- a keyed burner mounting bracket, wherein said keyed burner mounting bracket and said burner mounting box align said burner to said heat exchanger tube, to prevent the passage of a significant amount of ambient air therethrough, and so that there is no substantial movement of said burner;
- a gas manifold operably connected to said burner, wherein said burner comprises a top opening and a bottom opening, so that when the fryer assembly is in use, a mixture of gas and air exits said gas manifold and enters said bottom opening of said burner, travels in an upward direction, and exits at said top opening of said burner,
- a pilot assembly, said pilot assembly being operably connected to a source of gas, and
- a pilot carryover structure connected to said burner mounting box,
- the method comprising the steps of:
- determining a set point of operation for said oil;
- supplying gas to said pilot assembly;
- measuring the temperature of said oil, and if said temperature is less than said set point, supplying gas to said gas manifold, energizing said pilot assembly, and forming a pilot flame, so that said pilot carryover structure propagates said pilot flame to said screen of said burner, and ignites said air and gas mixture exiting therefrom, and
- if said temperature is greater than or equal to said set point, shutting off the supply of said gas to said gas manifold.
