ABSTRACT:
A rotary connector for coupling at least one stationary pipe to a rotating pipe includes a casing which is connected to a stationary inlet pipe and a stationary outlet pipe and which houses a rotary stem. The rotary stem includes an inner stem disposed within an outer stem for providing a first and second fluid flow path through the rotary stem. A spool is positioned between the rotary stem and the rotating pipe, which leads to a rotating piece of equipment, such as a combustor. The spool has an inner sleeve disposed within an outer sleeve for providing first and second fluid flow paths through the spool. The rotary connector also includes a seal for sealing an inboard end of the casing and a blind flange for sealing an outboard end of the casing. The fluid flows from the inlet pipe, through apertures in the outer stem, through an annulus between the inner and outer stems, through an annulus between the inner and outer sleeves of the spool, and into the coaxial pipe. After the fluid exits the rotary equipment, such as the combustor, the fluid flows back through the coaxial pipe, through the inner sleeve of the spool, through the inner stem of the rotary stem, through apertures in the outer stem and into the outlet pipe attached to the casing.
