The variation of the steam consumption rate ṁ (kg/h) with the turbine load during throttle governing is linear and is given by the “willan’s line”. [1] The equation for the willan’s line is given by: ṁ=aL+C. Where a is the steam rate in kg/kWh, 'L' is the load on turbine in KW and C is no load steam consumption.
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
The modern steam turbine was invented in 1884 by Charles Parsons, whose first model was connected to a dynamo that generated 7.5 kilowatts (10.1 hp) of electricity. [12] The invention of Parsons' steam turbine made cheap and plentiful electricity possible and revolutionized marine transport and naval warfare. [13] Parsons' design was a reaction ...
Cut-away drawing of steam engine speed governor. The valve starts fully open at zero speed, but as the balls rotate and rise, the central valve stem is forced downward and closes the valve. The drive shaft whose speed is being sensed is top right Porter governor on a Corliss steam engine. The devices shown are on steam engines.
An auxiliary oil system pump is used to supply oil [clarification needed] at the start-up of the steam turbine generator. It supplies the hydraulic oil system required for steam turbine's main inlet steam stop valve, the governing control valves, the bearing and seal oil systems, the relevant hydraulic relays and other mechanisms.
A common example of a thermal power plant that produces electricity by the consumption of fuel is the nuclear power plant. Nuclear power plants use a nuclear reactor's heat to turn water into steam. [1] This steam is sent through a turbine which is connected to an electric generator to generate electricity.
A steam–electric power station is a power station in which the electric generator is steam-driven: water is heated, evaporates, and spins a steam turbine which drives an electric generator. After it passes through the turbine, the steam is condensed in a condenser. The greatest variation in the design of steam–electric power plants is due ...
Arabelle Solutions, formerly GE Alstom Nuclear Systems, or GEAST, for ‘GE Alstom’, most of which was spun off from GE Steam Power, is a French multinational specialising in nuclear activities related to steam turbines (Arabelle) for the conventional island, present in nearly 16 countries including China, Finland, India, Romania and the United Kingdom, and headquartered in Boulogne ...
