Understanding Boiler Pressure | Boiler
Every boiler pressure vessel If the tag is illegible or missing, there will also be a stamped marking on the actual pressure vessel itself with its unique identifier and MAWP. If the MAWP is 15 PSI or below, it's low pressure. Anything higher than that means the boiler is defined as a high pressure boiler.
A boiler explosion is a catastrophic failure of a boiler. There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions. The second kind is a fuel/air …

Apr 10, 2018 · Pneumatic instruments mounted inside larger enclosures with other devices tend to protect them all by providing a positive pressure air purge for the entire enclosure. Some pneumatic instruments can also work in environments of high temperature and high radiation that would damage electronic instruments.
The following instruments should be provided in a boiler house control room: 1. Visbreaker gasoline storage tank low-level alarm. 2. Visbreaker gasoline supply header, pressure indication, and low-pressure alarm. Surge drum. Provision should be made to pump LPG directly into the flare header (if necessary). * LPG surge drum.
