Abstract:
A scroll for a combustion system having a compressor for supplying compressed air to a casing, a combustor arranged inside the casing for receiving the compressed air from the compressor and generating combustion gas, and a turbine arranged along substantially the same axis as the compressor for generating mechanical power based on the combustion gas generated by the combustor, the scroll comprising:a scroll main body arranged inside the casing and having an upper opening for receiving combustion gas from the combustor, and a lower portion shaped to guide combustion gas toward a lower opening for directing combustion gas toward the turbine; anda scroll housing arranged between the casing and the scroll main body so as to guide compressed air received from the compressor along a path having a substantially uniform cross-sectional area, and encompassing a portion of the scroll main body extending between a first end connected to an outlet of the compressor and a second end open toward the lower portion of the scroll main body and the combustor such that the compressed air received from the compressor is directed toward the lower portion of the scroll and into the combustor.
