The ratio of the power sent out by the plant to the energy produced from the fuel, in percent usually
thermal
A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.
no
It can be up to 40 percent in modern plants, less in old ones
The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)
The efficiency of a steam power plant is typically around 30-40%. This means that only 30-40% of the thermal energy from the fuel is converted into electrical energy, with the rest being lost as waste heat. Factors such as the type of plant, operating conditions, and technology used can affect the efficiency.

Mechanical efficiency is determined by dividing the output work by the input work, while thermal efficiency is calculated by dividing the useful work output by the heat input. Relative efficiency is the ratio of mechanical efficiency to thermal efficiency and can be used to compare the effectiveness of a machine in converting input energy to useful work.
The maximum Thermal Efficiency of Petrol Engine or Gasoline Engine or Otto Cycle Engine is about 25-30%.
Thermal efficiency is a measure of how efficiently a system converts heat energy into mechanical work. It is calculated by dividing the desired output (such as work) by the input energy (such as heat) and is expressed as a percentage. Higher thermal efficiency indicates that more of the input energy is being converted into useful work.
Air Preheaters (APH) are important equipments in modern thermal power stations. By preheating the combustion air with the hot flue gases coming out of the boiler, a considerable increase in efficiency is obtained.
Factors of thermal efficiency include combustion efficiency, heat transfer efficiency, and frictional losses. Combustion efficiency refers to how well fuel is converted into heat energy, while heat transfer efficiency measures how effectively heat is transferred within the system. Frictional losses occur due to resistance in moving parts and can reduce overall energy output. Improving combustion efficiency, enhancing heat transfer mechanisms, and minimizing frictional losses can all help increase thermal efficiency.
