  "textContent": "The present invention relates to a dual-volume volute (10) for a gas turbine (50) comprising a circumferential spiral-shaped conduit (11), a first opening (12) arranged tangentially to said circumferential conduit (11) towards the exterior of said circumferential conduit (11) and a second circumferential opening (13) arranged at the center of said circumferential conduit (11). A wall (15) separates said circumferential conduit (11) into two symmetric volumes (18,19), a first fluid and a second fluid being able to circulate independently and in an isolated manner between said first opening (12) and said second opening (13). Said first opening (12) allows linear flow of the two fluids between said circumferential conduit (11) and a volume exterior to said circumferential conduit (11) whereas said second opening (13) allows radial flow of these two fluids between said circumferential conduit (11) and a volume interior to said circumferential conduit (11).",
