Direct Steam Injection Humidification: Is It Safe For

Mar 23, 2001 · "These concerns typically fall into four categories: Regulatory, safety, technical, and economic," says Cicero. From the regulatory perspective, there are laws that prohibit the use of some steam system corrosion inhibitors. The best example is the dairy industry, where until recently, only ammonia was acceptable for use in these systems.

Boiler explosion - Wikipedia

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.

Corrosion in steam boilers - FINEAMIN

Deposits of ferric oxides and dissolved salts of calcium, magnesium, iron, copper and / or aluminum contribute all together to opening new corrosion mechanisms inside the steam boiler. These deposits can act as thermal insulation particularly in areas of high heat transfer which may cause local overheating and heavy corrosion inside the boiler drum and pipes.

Stress corrosion cracking (SCC) in boilers and cooling

Jan 01, 2011 · In boilers, the 'caustic embrittlement' noted in early, riveted boiler drum designs, has been attributed to have caused numerous catastrophic ruptures in steam locomotives and steam-powered ships. In ambient water environments, 'season cracking' was noted over 100 years ago in brass metal during the rainy season in the tropics.
