[0002] Steam condensate refers to the water form transformed when steam is cooled. When high-temperature steam encounters a low-temperature surface or environment, due to heat transfer, the thermal energy in the steam will transfer to the condensation surface, causing the water vapor molecules in the steam to condense into liquid water. The heat released by the steam during the condensation process will cause the temperature near the condensation surface to rise.
