Engine order telegraph. An engine order telegraph or E.O.T., also referred to as a Chadburn, [1] is a communications device used on a ship (or submarine) for the pilot on the bridge to order engineers in the engine room to power the vessel at a certain desired speed.
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”. 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.
The devices shown are on steam engines. Power is supplied to the governor from the engine's output shaft by a belt or chain connected to the lower belt wheel. The governor is connected to a throttle valve that regulates the flow of working fluid (steam) supplying the prime mover. As the speed of the prime mover increases, the central spindle of ...
Bandwidth throttling consists in the limitation of the communication speed (bytes or kilobytes per second), of the ingoing (received) or outgoing (sent) data in a network node or in a network device such as computers and mobile phones. The data speed and rendering may be limited depending on various parameters and conditions.
Traffic shaping provides a means to control the volume of traffic being sent into a network in a specified period ( bandwidth throttling ), or the maximum rate at which the traffic is sent ( rate limiting ), or more complex criteria such as generic cell rate algorithm. This control can be accomplished in many ways and for many reasons; however ...
The aftermath of a boiler explosion at Strømmen station near Oslo, Norway, 22 December 1888. One locomotive was thrown into the air and landed on the roof of another; the crews of both escaped without injury A boiler explosion is a catastrophic failure of a boiler. There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be ...
Wide open throttle. Wide open throttle or wide-open throttle ( WOT ), also called full throttle, is the fully opened state of a throttle on an engine ( internal combustion engine or steam engine ). The term also, by extension, usually refers to the maximum-speed state of running the engine, as the normal result of a fully opened throttle plate ...
The efficiency of an engine is defined as ratio of the useful work done to the heat provided. where, is the heat absorbed and is the work done. Please note that the term work done relates to the power delivered at the clutch or at the driveshaft . This means the friction and other losses are subtracted from the work done by thermodynamic expansion.
