| turbine | A machine for converting the heat energy in steam or high temperature gas into mechanical energy. In a turbine, a high velocity flow of steam or gas passes through successive rows of radial blades fastened to a central shaft. (05 Dec 1998) |

| turbinectomy | Surgical removal of a turbinated bone. Origin: turbinate + G. Ektome, excision (05 Mar 2000) |
| turbinella | <zoology> A genus of large marine gastropods having a thick heavy shell with conspicuous folds on the columella. Origin: NL, dim. Fr. L. Turbo, -inis, a top. Source: Websters Dictionary (01 Mar 1998) |
| gas turbine | (combustion turbine) A turbine that converts the energy of hot compressed gases (produced by burning fuel in compressed air) into mechanical power. Often fired by natural gas or fuel oil. (05 Dec 1998) |

| condensing turbine | A turbine used for electrical power generation from a minimum amount of steam. To increase plant efficiency, these units can have multiple uncontrolled extraction openings for feedwater heating. (05 Dec 1998) |
| steam turbine | A device for converting energy of high-pressure steam (produced in a boiler) into mechanical power which can then be used to generate electricity. (05 Dec 1998) |
| noncondensing, controlled extraction turbine | A turbine that bleeds part of the main steam flow at one (single extraction) or two (double extraction) points. (05 Dec 1998) |
| topping and back pressure turbine | Turbines which operate at exhaust pressure considerably higher than atmospheric (noncondensing turbines). These turbines are often multistage types with relatively high efficiency. (05 Dec 1998) |
| francis turbine | A water-powered turbine used to transform water falling vertically to mechanical (rotating) energy. (05 Dec 1998) |
