TURBINES Definition. ‘TURBO MACHINE’ is defined as a device that extracts energy or imparts energy to a continuously flowing fluid by the dynamic action.

rotate in some way. If the turbo machine adds energy to the fluid, it is commonly called a ‘PUMP’ and if it extracts energy, as in case of steam turbines, then it is called a ‘TURBINE’ A steam turbine is mainly used as an ideal prime mover to drive the electric generators in thermal power plants to generate electric power. In steam turbines/

Important to note that the turbine size effects boost threshold, turbo lag and fuel consumption. Boost threshold is the engine speed at which there is sufficient exhaust gas flow to generate positive (intake) manifold pressure, or boost. This is the/ achieve 22% reduction in fuel consumption and CO 2 emissions, including a reduction of 62% at idle conditions. Advanced Turbo-charging Systems Higher volumetric efficiency is achieved through increased pressure @ IVC. Go back to Era of Otto or Diesel. /
