Chemical Cleaning Solvents; Boiler Descaling with Tetra-Ammonium Ethylene-Diamine Tetra-Acetic Acid

Abstract

The tetraammonium salt of ethylenediamine tetraacetic acid is an effective agent for removing scale from naval boilers. The cleaning procedure effects significant savings in cleaning time and post-cleaning boiler readiness operations. However, the release of toxic ammonia gas into confined machinery spaces as a result of leakage and the corrosive effects upon alloys such as Monel and 2 1/4-1 chrome-molybdenum steel present serious doubts as to its employment for cleaning naval boilers.
