Overview:
This white paper demonstrates how dealkalization of boiler feed water improves boiler steam/condensate systems reliability, and highlights the fuel and chemical savings that can be realized. It provides an overview of the operating expenses for low pressure boilers, lists the various parameters that affect their operating efficiency, and reviews the impact of scale deposition on the boiler tube surfaces with the help of a graph. A list of general ASME guidelines for low pressure boilers is given, along with a table of data depicting the expected life of a schedule 40 pipe with varying corrosion rates and a graph representing the relationship between condensate flow and corrosion rate. The report includes a case study of a boiler feed water system that features a dealkalizer at a beverage distilling company. Case study illustrates the benefits of dealkanization, and also presents the expected steam, heat, and fuel savings as tabular data.
