Brashears, D F

A combustion apparatus which has a burner having an inner wall lined with a refractory material forming a combustion chamber and an outer wall spaced from the inner wall by spacing members. A primary air supply supplies air to the burner combustion chamber through the outer and inner walls. A pulverizer for pulverizing solid fuel is connected to the primary air supply for feeding the pulverized solid fuel to the burner combustion chamber. A secondary air supply supplies air to the burner between the inner and outer walls and into the burner combustion chamber. The secondary air supply supplies air to an area of negative pressure in the combustion chamber created by the swirling flow of air from the primary and secondary air supply. An ignition pilot is mounted through the burner inner and outer walls adjacent to the primary air and fuel feed. The ignition pilot has a pilot flame detector which looks at the pilot and the main combustion flame. The primary air supply can also have a gas connection for supplying gas with the primary air supply and an oil atomizer gun can be attached for running the burner with fuel oil.
