Abstract:
A solid fuel fed combustor system comprising:a first chamber portion having an inlet feed for feeding a metered amount of a solid fuel thereto, a first burner stage having a first traveling conveyor firebelt with a first air introducing means for introducing a metered amount of air in progressively increasing proportion along the length of said first traveling conveyor to cause endothermic decomposition of said solid fuel, a second burner stage having a second traveling conveyor firebelt with a second air introducing means for introducing air in a progressively decreasing amount along the length of said second traveling conveyor firebelt and to cause exothermic decomposition of solid fuel received from said burner stage, first chamber portion having a sloped common roof section common to said burner stages and made of radiative energy reflective fire brick, said roof section being angled to reflect radiative energy generated from fuel traveling on said traveling conveyor firebelts and to direct said radiative energy onto fuel traveling on said first firebelt, and means for controlling air introduced to said burner stages.
