DEVELOPMENT OF FACILITIES FOR SHIPBOARD CHEMICAL CLEANING OF BOILERS

Abstract

Several descalants that can be safely handled by non-technical ship's personnel were evaluated for chemical cleaning of shipboard boilers. The selected descalant must be a non-toxic, water-soluble solid formulation and its solutions posses scale removing properties similar to inhibited hydrochloric acid and at the same time be non-corrosive to boiler steels. Wyandotte CHEMICALS Corporation, under contract with the Bureau of Ships, conducted bench-scale evaluations on scaled boiler tube sections using various formulations. The laboratory continually monitored the application of the Wyandotte-suggested procedures to full scale boiler cleaning trials. Based on these tests, a chemical cleaning procedure was developed that is suitable for shipboard use. The selected descalant formulation consists of 89% SULFAMIC ACID, 6% citric acid and 5% diethylthiourea.
