If gravity is not utilized from the trap to the return pipe, the trap and drain must be drained manually or automatically using a drain equipped with antifreeze. In cases where multiple traps are installed in the same trap station, maintaining the temperature of the traps can help prevent freezing. Proper selection and installation of a suitable trap will typically avoid freezing issues as long as steam flows through it. However, if the steam supply is interrupted, condensate may create a vacuum within the heat exchanger or associated piping, which can restrict the free flow of condensate before freezing occurs. To prevent this, a vacuum breaker is usually installed between the discharge equipment and the trap.
A preliminary summary of the first valve:
If gravity is not used from the trap to the return pipe, the trap and drain should be drained manually or automatically using a drain with antifreeze. When multiple traps are installed together in the trap station, keeping them warm can help prevent freezing. Choosing and installing an appropriate trap ensures that freezing problems are avoided as long as steam passes through it. However, if the steam flow is disrupted, condensate can create a vacuum in the system, blocking the release of condensate before it freezes. Therefore, a vacuum breaker is installed between the discharged equipment and the trap to prevent such issues.
Specific antifreeze measures include:
1. The trap size should not be excessively large.
2. The trap discharge line should be kept as short as possible.
3. The discharge line should be sloped downward to enhance gravity drainage.
4. Both the trap discharge line and the condensate return line should be insulated.
5. If the condensate return line is exposed to atmospheric conditions, consider using a heat pipe for protection.
6. If the return pipe rises, a vertical discharge pipe should be installed near the top of the return header, and both the discharge pipe and the trap discharge line should be insulated together.
