Blowdown Vessels
- Description
- This type of plant is an integral part of a steam boiler system.
Their purpose is to contain the hot water and suspended solids blown down from the steam boiler before it is released to the drains.
- Applicable Legislation
- PSSR
- Periodicity of Inspection
- Same periodicity of the boiler to which it is connected:
Shell boiler - 14 months
Water tube boiler - 26 months
- Why Inspect It
- The main hazard with this type of plant is that the vessel may fail because its safe working pressure has been exceeded or because its ability to withstand pressure has been reduced through in-service degradation e.g. corrosion or fatigue.
