The pressure in the cylinder declines after cutoff as the steam pushes the piston down its bore. Cutoff is one of the four valve events. Early cutoff is used to increase the efficiency of the engine by allowing the steam to expand for the rest of the power stroke, yielding more of its energy and conserving steam. This is known as expansive working.
The efficiency of a conventional steam–electric power plant, defined as energy produced by the plant divided by the heating value of the fuel consumed by it, is typically 33 to 48%, limited as all heat engines are by the laws of thermodynamics (See: Carnot cycle). The rest of the energy must leave the plant in the form of heat.
The Tennessee Valley Authority (TVA) is the primary utility in Tennessee which generates electricity and sells it to hundreds of local utilities and industrial customers. [2] Like most of the US, the sources used to generate power in Tennessee have changed substantially in the last decade.

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work.
Nissan, which has its U.S. headquarters in Franklin, announced the company will be cutting 9,000 jobs following a challenging year. Officials have not announced if the Smyrna plant will be affected.
Cooling tower Nuclear power plant. Power plant engineering, abbreviated as TPTL, is a branch of the field of energy engineering, and is defined as the engineering and technology required for the production of an electric power station. [1] Technique is focused on power generation for industry and community, not just for household electricity ...
Nashville-based Bridgestone Americas plans to shutter its tire plant located in La Vergne, Tennessee, later this year, which will leave 700 workers based in Rutherford County without jobs.
