As can be clearly seen in the above diagram, the steam trap serves as a physical separation point between the steam system and the condensate system, as well as a pressure separation point between the two systems. The reliable operation of the steam trap not only affects the efficiency of heat exchange equipment but also the safety and reliability of the condensate system. Using the heat transfer formula for steam heat exchange, we can obtain that Q = K•A•△tm. Here, Q represents the heat flow rate (in W), △tm is the logarithmic mean temperature difference (in °C), and A is the heat transfer area (in m2). Given that the heat exchanger determines K and A to a certain extent, the main factor affecting the amount of heat transferred is the steam temperature, which in turn determines △tm, the logarithmic mean temperature difference (in °C). For saturated steam, it is the pressure of the steam that determines its temperature. The steam trap is very important as the pressure cut-off point between the steam and condensate systems. The stability of heat output relies, on one hand, on the regulation of the supply pressure, and on the other hand, on the steam trap’s role in maintaining this pressure stable. Just as maintaining the water tank level relies on the inlet and outlet valves. The absence of a reliable hydrophobic system not only affects the stable operation of heat exchange equipment but also tends to cause oscillations in the steam temperature control valve.
