Vacuum Breaker Systems After boiler shut down, the steam inside the vessel condenses as the shell cools. This creates a vacuum which will siphon water into the boiler from the water feed or condensate return system, flooding the boiler. A vacuum breaker permits outside air to enter into the shell to relieve the vacuum, thus prevent-Learn More
Apr 27, 2020 · Back in the days of coal and wood fired boilers, heating contractors used vacuum air vents to help them get the maximum efficiency out of their steam heating systems. They called these old systems "Vapor/Vacuum," and the principle that made them work was a simple one: At very low pressure, steam …Learn More
Vacuum deaeration has been used successfully in water distribution systems. However, pressure deaeration (with steam as the purge gas) is normally used to prepare boiler feedwater. Steam is chosen as the purge gas for several reasons: it is readily available. it …Learn More

Dec 23, 2020 · Another place where unwanted vacuum shows up in a steam-heating system is on jobs that have motorized zone valves at the boiler. These are normally on the takeoffs from the boiler header. When the zone valve closes, the steam between the zone valve and the boiler will condense, leaving you with a vacuum inside the boiler.Learn More
Steam Boilers. Steam Boilers are a form of large water content boilers used to provide customers with steam, as a heat transfer media. Typically, the quality of steam provided by these units is much higher than forced circulation steam generators. The higher quality of steam mitigates the use of steam separators or steam accumulators.Learn More
