Water Softening and Treatment

Abstract

THE primary object of this book is the softening of hard raer for use in steam boilers and for manufacturing purposes, but, in fact, it deals largely with other matters relating to the supply of water to the boilers of steam engines. Thus it is divided into five sections, the first only of which relates to the treatment of water by softening, together with the separation of oil and filtration, and occupies about half the book; whereas the four other sections, constituting the second half of the book, consist of “Section II., Air Pumps, Condensers, and Circulating Pumps”; “Section III., Feed Heating and Stage Heating ”; “Section IV., Water Cooling ”; and “Section V., Feed Pumps and Injectors.” Accordingly, the volume ranges, over the whole subject of the treatment of water supplied to steam boilers, though dealing more expressly with the all-important point of securing, so far as practicable, the purity of the water employed for raising steam.
