Those involved in the design, operation, or maintenance of industrial boilers will find this book an invaluable source of information. First the author discusses the relationship between boilers and the generated steam. The prevention of scaling, corrosion, stress corrosion cracking, and steam contamination are fully explored followed by an in-depth examination of the chemical treatments necessary to implement preventative measures. Specific types of boilers are discussed, water treatment programs and operating guidelines are outlined. Finally, step-by-step procedures are given for testing boiler water for the various contaminants. The clarity and accuracy of presentation allows this book to function as a manual as well as a text. CONTENTS: Principles of Steam Generation; Objectives in Treating Water for Boilers; Physical methods for Improving Water Quality; External Chemical Treatments; Internal Chemical Treatments; Operating Procedures; Complications in the Operation of Boilers: Analytical Methods;
