Pricing method for steam
Thread Content
I would like to ask everyone: is the pricing for steam based on its enthalpy or on temperature and pressure? For example, the pressure of saturated steam at different pressures: At 1.0 Mpa, the heat enthalpy of the steam is 664.2 Kcal/kg, with a temperature of 180°C. At 0.4 Mpa, the heat enthalpy is 655 Kcal/kg, and the temperature is 151°C. At 0.2 Mpa, the heat enthalpy is 650.2 Kcal/kg, corresponding to a temperature of 133°C. At 0.12 Mpa, the heat enthalpy is 642 Kcal/kg, with a temperature of 104°C. If the heat enthalpy values are similar, then the price of the steam should also be similar. By this logic, shouldn’t the price of superheated steam at 1.2 Mpa be similar to that of saturated steam at 50 Kpa?
Originally, the price difference was small; generally, there is a somewhat greater loss of saturated steam； Investments with higher pressure are higher
