When a thermal power plant operates in winter or summer, which season has the highest thermal effici

Of course, it is winter, because the temperature of the circulating water entering the condenser is lower in winter, and relatively speaking, the temperature difference with the main steam is greater. According to the principle of thermodynamic cycle, the greater the temperature difference, the easier it is to convert the thermal energy of steam into energy. For boilers, because the inlet air temperature is lower in winter than in summer, the same volume of air must absorb more heat to reach the same temperature, thereby lowering the gas temperature. boiler exhaust and increasing the thermal efficiency of the boiler. efficiency. However, for northern power plants that need to invest in heaters, separate calculations are required.
