How vacuum can cause steam problems - Heating Help

Jun 24, 2014 · And that's the problem. You see the new boiler-feed pump has a vent that's open to the atmosphere. It's not part of the vacuum loop that makes up the rest of the system (boiler, to supply mains, to radiators, to return mains). As the vacuum pump sucks on the system, it's also sucking on the air from the surface of the boiler water.

Hydrogen: The Burning Question - Features - The Chemical

Small amounts of hydrogen sulfide occur in crude petroleum, but natural gas can contain up to 30%. Volcanoes and some hot springs (as well as cold springs ) emit some H 2 S, where it probably arises via the hydrolysis of sulfide minerals, i.e. MS + H
