Abstract: The rotatable machine includes a compressor and an inner annular casing circumscribing at least a portion of the compressor. The inner annular casing includes a radially outer surface. The inner annular casing includes a radially outer surface, a vertically upper portion, and a vertically lower portion. The clearance control system includes a manifold system including a manifold system includes at least one conduit extending circumferentially around the vertically lower portion of the inner annular casing. The clearance control system includes a header system including at least one header extending circumferentially around only the vertically lower portion of the inner annular casing. The at least one header configured to receive a flow of cooling fluid from the at least one conduit. The at least one header configured to channel the flow of cooling fluid to the vertically lower portion of the radially outer surface of the inner annular casing.

Abstract: A cooling system includes a first conduit positioned within a cavity and extends from a radially inner casing aperture to a radially outer casing aperture. The cooling system also includes a second conduit coupled in flow communication with the first conduit and extending into the cavity. The cooling system further includes at least one valve positioned within the first conduit and the second conduit. The at least one valve and the first conduit are configured to channel a first fluid from the radially inner casing aperture to the radially outer casing aperture during a first mode of operation. The at least one valve, the second conduit, and the first conduit are configured to channel a second fluid from the radially outer casing aperture to the cavity during a second mode of operation.
