Abstract
A new and improved low emission combustor comprises a plurality of concentric cylindrical shells spaced radially to provide air supply and cooling passages and a primary fuel supply means disposed at the inlet end and a secondary fuel supply means disposed at the outlet end and arranged so that fuel supplied by the primary fuel supply means is less than that required for full load operation and the remainder of the fuel required to full load being supplied as needed by the secondary fuel supply means. Regeneratively heated combustion and cooling air is provided at the inlet and exit ends of the combustion chamber and at various intermediate locations along the length thereof to effect staged combustion and flame cooling.
