As long as steam passes through, there will be no freezing problem in the selection and installation of suitable traps. But if the steam breaks, the steam condensate will form a vacuum in the heat exchanger or the accompanying pipe. This prevents condensate from freely discharging from the system before freezing occurs. Therefore, a vacuum destroyer should be installed between the discharge device and the trap. If gravity discharge is not used from traps to return pipes, traps and discharge pipes should be manually discharged or automatically discharged using discharge pipes with anti-freezing measures. In addition, when multiple traps are installed together in the trap station, the trap insulation can prevent freezing.
Antifreeze measures include:
1. Drain valve should not be too large.
2. Keep drain line as short as possible.
3. Tilt down the drain line of the trap to speed up the gravity drainage.
4. The drain pipe of trap and the condensate return pipe should be insulated.
5. When condensate backwater pipeline is exposed to atmospheric conditions, heat tracer should be considered.
6. If the backwater pipe rises, the vertical discharge pipe should be adjacent to the discharge pipe on the upper part of the backwater catchment, and insulate the discharge pipe and the drain pipe of the trap together.
