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.

A combustion apparatus comprising in combination: a burner having outer and inner walls spaced with spacing members in a predetermined spaced relationship to each other; said inner wall forming a combustion chamber thereinside; solid fuel input means passing through said burner outer and inner walls

A combustion apparatus comprising in combination: a burner having outer and inner walls spaced with spacing members in a predetermined spaced relationship to each other; said inner wall forming a combustion chamber thereinside; solid fuel input means passing through said burner outer and inner walls for directing fuel into said combustion chamber; a source of air directed into the space between said inner and outer walls; a plurality of passageways through said inner walls for directing air from said source of air through said openings into said combustion chamber, said plurality of passageways including angled passageways, staggered in said inner wall and directed into the primary burn zone; and reverse air jets for directing air through one end of inner wall into an area of negative pressure generated by said staggered angled air jets in said combustion chamber.
