- 1 - Abstract: A burner assembly of the type wherein both the combustion air and the gaseous fuel are controlled by a pressure equalizing control device, comprises an inner barrel and a combustion air preheating passage both arranged exteriorly of a gaseous fuel supply tube. An annular space is defined exteriorly of the gaseous fuel supply tube and communicates with the preheating passage through at least one perforation in the inner barrel. An exhaust passage is provided with an exhaust gas sucking device and is disposed adjacent the preheating passage. The arrangement enables the air-fuel mixing ratio to be kept relatively constant.
