Water Quality Control of Auxiliary Boilers of Recent Ocean Ships -For Review and Standardization of Water Analysis Log Sheet

Abstract

 In past several years, auxiliary boilers of 1MPa or less have experienced water quality control problems. Most of these have been caused by the malfunction of the support system related to water quality control. The support system consists mainly of 4 components, namely, boiler compounds, water quality standards, water quality measurements, and log-sheets. Among these, the boiler water quality standards are the most important. However, there are not clearly established corresponding to the present situation because there are various viewpoints among the chemical makers, the boiler makers, and the shipping companies or their management companies. As for the log sheet, a requirement to review and standardize the log sheet form of boiler water analysis should be established in order to improve the support system. This paper, therefore, studies the water quality control and standards of auxiliary boilers for log sheet standardization, and for support system improvement.
