Horizontal Multibar Steam Boilers
- Description
- This type of plant is used in a variety of situations and industries. Typically steam is used for production purposes, power generation, heating and sterilisation.
Systems generally comprise of steam boiler, blowdown receiver, pipework and protective devices e.g. safety valve, pressure gauge, water level controls, water level gauges and flame failure devices.
- Applicable Legislation
- PSSR
- Periodicity of Inspection
- Horizontal Multi-tubular Boilers; Vertical Boilers; Autoclaves - 14 months
Water-tube Boilers - 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, fatigue or lack of appropriate water treatment.
