Abstract

A boiler burner is configured for use in a horizontally fired boiler, such as a flame tube boiler or a water tube boiler. The burner may include proximal fuel and air sources providing a flow into a proximal inlet of a mixing tube that conveys the main fuel and combustion air to an outlet of the mixing tube. The burner may also include a flange configured to be mounted to an opening of a boiler and structured to support a weight of the boiler burner when the boiler burner is oriented horizontally for horizontal firing. A distal pilot burner disposed distal to the outlet of the mixing tube may be configured to hold a combustion reaction of the main fuel and combustion air.
