What is Thermal Efficiency - Definition

In a modern coal-fired power plant, the temperature of high pressure steam (T hot) would be about 400°C (673K) and T cold, the cooling tower water temperature, would be about 20°C (293K).For this type of power plant the maximum (ideal) efficiency will be: = 1 – T cold /T hot = 1 – 293/673 = 56%. It must be added, this is an idealized efficiency.The Carnot …
