It has been demanded more and more to improve the reliability of boiler water treatment, and also to establish the appropriate water quality control corresponding to the recent situation of actual ships. The authors have investigated the present state of water treatment of marine low pressure boilers, and have made a new recommendation regarding criteria and monitoring for water quality control, which have been accepted by the Boiler Subcommittee of JIME Energy Systems Committee. In order to improve the reliability of boiler water control, the experimental investigations have been carried out on the influence of sea water mixing on boiler water quality. This paper describes the experimental results, which reveal that a new model should be proposed regarding the chemical reaction system of scale components and water treatment chemicals of phosphate/alkali type. The paper describes further the other experimental investigations carried out for the development of an automatic boiler water quality control.
