Description

technical field [0001] Embodiments of the present disclosure relate to the field of energy technology, and in particular to a method, device, electronic device and medium for determining the saturation temperature of water vapor. Background technique [0002] Industrial boilers producing high-temperature and high-pressure steam are widely used in various fields of industry, and the steam produced is used for heating, process manufacturing and other purposes. The steam produced by industrial steam boilers is generally water vapor, and its temperature is higher than saturated steam at the same pressure. Because steam boilers generally only have corresponding temperature, pressure, and flow measuring points, it is impossible to directly obtain the superheat of the output steam, and steam thermal calculation is the basis of heat balance calculation of industrial thermal systems. Therefore, it is usually necessary to calculate the saturation temperature of steam. So as to calcul...

[0011] However, the above-mentioned method of checking the thermodynamic property diagram or table of water and water vapor is a traditional method for steam thermodynamic calculation. Because the thermodynamic property diagram and table of water and water vapor are relatively complicated, it is necessary to manually calculate the water and steam according to the pressure of water vapor. The corresponding saturation temperature is marked in the thermodynamic property diagram or table of water vapor. This method is time-consuming and labor-intensive and does not have real-time calculation capabilities.
