An Introduction to Steam Boilers and Steam Raising

2013-2-13·The steam that makes intimate contact with the water droplets then scrubs the dissolved gases by its counter-current flow. The steam heats the water to within 3-5 º F of the steam saturation temperature and it should remove all but the very last traces of oxygen.

Characteristics of boiler feedwater - Lennte

Since water impurities cause boiler problems, careful consideration must be given to the quality of the water used for generating steam. The composition of boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the boiler, without exceeding the tolerance limits of the particular boiler

Ethanolamine - Wikiped

2019-7-28·Ethanolamine (2-aminoethanol, monoethanolamine, ETA, or MEA) is an organic chemical compound with the formula HOCH2CH2NH2. The molecule is bifunctional, containing both a primary amine and a primary alcohol. Ethanolamine is a colorless, viscous liquid with an odor reminiscent of ammonia.[8] Its derivatives are widespread in nature; e.g

Utilities: Dont Get Steamed | Chemical Processi

2019-8-1·An examination of the effects of some of these impurities reveals why the limits are so low. Consider chlorides. Even small amounts that enter the steam generator, say, from a condenser tube leak or contaminated condensate return, if chronic and not neutralized by the boiler-water treatment program, will concentrate under deposits on boiler internals.
