Thermostatic valve and condensate phase separation tank

Pay main attention to the liquid level in the condensate phase separation tank

My phase separation tank is placed on the ground; I remember someone saying before that the liquid level in the phase separation tank should be kept at the same level as the liquid level inside the heat exchanger.

The check valve–not good quality, I guess. Our company has installed steam traps. No cans were used

Some design institutes are not accustomed to using steam traps, and the failure rate is relatively high; it might be a quality issue. Thank you for your reply.

May I ask, is the steam used high-pressure or low-pressure? A few kilograms? I have ones with a liquid separation tank, and ones with a steam trap

Pay attention to the liquid level control of the condensate phase separation tank.

A steam trap serves as a physical separation point between steam systems and condensate systems, 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 impacts 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). When the heat exchanger is fixed, meaning that K and A remain constant, the main factor affecting the amount of heat transferred is the steam temperature, as it 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 depends, on the one hand, on the regulation of the supply pressure, and on the other hand, on the steam trap’s ability to maintain this pressure at a stable level. 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.

In cases of high flow rates, a condensate tank should be used first, followed by a steam trap, for example, on the evaporator

If it is high-pressure steam, isn’t it difficult to measure the liquid level in the condensate phase separation tank?

5 kilograms of steam – what does this choice have to do with pressure?
