Gas-fired fryer and gas-fired burner suitable therefor

摘要

In a fryer, a conduit (60) extends through a frypot (20) so as to be immersed in a frying oil. Combustion occurs in an inlet portion of the conduit. Products of combustion are exhausted through an outlet portion (64) of the conduit and through serpentine channels (94, 96) along certain walls of the frypot. Insulating panels (100) form outer walls of the channels. In a burner (30) for the fryer, a vortex of air is provided, and a minor portion of gas is ignited before a valve controlling a major portion of gas is opened. Means provide a minimum delay of one to three seconds, when it has been sensed that combustion has been established, before the valve is opened. IMAGE
