TOC Measuring of Boiler Water with Shimadzu's On-line TOC Analyzer

Introduction

Water supplied to boilers needs to be appropriately maintained to assure boiler performance and safe operation. The following types of damage can occur if organic matter - in particular fats and oils - is in the boiler supply water. 1. Foaming or carryover occurs and results in trouble. 2. The types of fats and oils that adhere to the inside of thc boiler become the adhering nucleus for corrosive products such as iron oxide and copper oxide, metallic scale forms, which leads to over heating of the heat transfer surface. 3. The oxidized product of organic matter corrodes the device. Therefore it is desirable to keep the concentration of fats and oils as low as possible in boiler supply water.
