In steam turbine technology that's a term with a double turbine. With a gas turbine as the prime mover, it's generally called by GE a combined cycle or STAG (STeam And Gas) plant. It tends to get a bit complicated as to layout - they are often designed with the gas and steamers in one line up, powering a single genset, others use one to as many as four GTs, each powering a genset, then a good size ST running a 5th gen set. We did that at a project of mine Mahmoudia, Egypt with smaller frame size GTs. I sure wish I still had my photos, but they got left in the project files when I retired
