Boilers that are “intermittently” used such as boilers in breweries, some plastics plants, and other locations where steam is not needed for all processes and manufacturing is done by ‘batch process” have long had the issue of making the decision as to whether to shut down the boiler or steam generator following protocols set forth by the manufacturer in between batches or keep it fired. Often when boilers are shut down for shorter periods of time these protocols may not be followed, as they are sometimes seen as “too labor and chemical intensive.”
Using traditional chemistries this becomes a tough decision as to whether to spend more on energy by keeping the boiler fired or to run the risk of corrosion and oxygen pitting in between uses, in the case of not following specific protocols, as well as the possibility of particulate (corrosion byproduct) being carried into the steam lines and contaminating the steam upon startup and operation.
The latest formulations of Film Forming Amines (FFA) using molecules such as cyclohexylamine, diethylaminoethanol, morpholine, octadecylamine, and other additives, appear to provide a much greater protection of boilers and steam generators during these shutdowns minimizing the worry of high corrosion and pitting levels. This paper seeks to provide field based data validating the claims that FFA’s perform better in intermittently operated systems.
This is a case study of a brewery that not only runs periodic batches of “brews” as a normal course of its operation but was also forced to shut down for much longer periods of time in 2020 due to COVID- 19 restrictions as production was severely curtailed. Throughout the course of this study the following information was collected an analyzed: Monthly reporting, chemical levels, water usage, chemical usage, as well as iron levels in the boiler water, and the condensate system samples when possible. Evidence from other studies using FFA will also be added to the presentation.
