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. 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 ...
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 ...

A key requirement for the high-speed steam engine was accurate control of a constant speed, even under a rapidly changing load. Although the control of steam engines via a centrifugal governor dates back to Watt, this control was inadequate. These early governors operated a throttle valve to control the flow of steam to the engine. This gives ...
Centrifugal governor in the Boulton & Watt engine 1788 Lap Engine. The centrifugal governor was adopted by James Watt for use on a steam engine in 1788 after Watt's partner Boulton saw one on the equipment of a flour mill Boulton & Watt were building. [58]
Earlier engines with Watt's centrifugal governor and throttle valve become inefficient when operating at low power. The Richardson governor [17] was used for stationary and portable engines produced by his employers, Robey & Co. [18] This is a simple link valve gear controlled automatically by a centrifugal governor. Rather than the Stephenson ...
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 centrifugal governor is a specific type of governor that affects the speed of an engine by regulating either the flow of the engine's working fluid (such as air or steam) or fuel (as in a Diesel engine). The flow is modulated so as to maintain a near constant speed over a range of mechanical load conditions."
