ABSTRACT:
A gas-fired infrared heater for projecting an infrared beam in a radiation pattern having a predetermined geometry for irradiating the surface of a food product or other body to effect uniform heating thereof at a rapid rate. The heater includes a ribbon-type burner having an elongated pre-mix casing into which is fed air and gas, and an outlet extending along a slot in the casing and projecting therefrom. The outlet is provided with two sets of corrugated ribbons separated by a gas pressure chamber, whereby the air-gas mixture from the casing passes through one set into the chamber where the pressure thereof is equalized before the mixture passes through the other set from which it emerges as a sheet of flame of uniform intensity. The outlet is inserted in the longitudinal socket of a refractory body to impinge on a surface thereof whereby the surface is heated to a temperature level causing the surface to emit infrared energy which is projected by an array of radiation horns formed in the assembly.
