ABSTRACT:
A kiln and method of firing kilns or the like in which high firing rate gas streams are introduced into the ware treating chamber in the form of pulsed jets and a continuous low firing rate gas stream is also introduced into the ware treating chamber for maintaining uniformity of temperature and atmosphere within the ware treating chamber. The time interval between the pulsed jets is controlled in accordance with the difference between a set predetermined temperature and the actual temperature in the ware treating chamber. Also disclosed is a burner for the kiln including coaxial primary and secondary nozzles for burning fuel. The primary nozzle burns fuel at a high rate and is pulsed intermittently while the secondary nozzle burns constantly at a low rate.
