How to Prepare Your Boiler for an Inspection

Periodic boiler inspections are necessary to ensure that all equipment and components are operating safely and properly. When removing a boiler from service, the proper procedures should be used to reduce thermal stress and prevent sludge from settling and “baking on” waterside surfaces.

If a boiler is cooled too rapidly or unevenly, the extreme expansion and contraction stress can cause leaks to develop on rolled tube ends as well as damage firebrick or refractory material. Rapid cooling and draining can also cause any suspended solids in the boiler water to form hard, difficult-to-remove deposits. These deposits not only reduce heat transfer efficiency but could also lead to a false interpretation of the treatment program results.

Biofilm, Amoeba, and Legionella

Biofilms are the root cause of serious problems in building potable and industrial water systems including clogged piping, reduced heat transfer efficiency, microbiologically-influenced corrosion, and Legionella transmission. Biofilms are dynamic, complex structures optimized for microbial growth and survival, which make them difficult to remove and control.

How Reverse Osmosis Works

From Design to Cleaning

How Reverse Osmosis Works

Reverse osmosis (RO) produces high-purity water for use in many applications, including low and high pressure boilers, manufacturing processes, cleaning, and ultrapure water systems.  RO offers numerous benefits that can save water, fuel, operating costs, labor, and more.  Understanding how it works will help in the selection, maintenance, and operation of RO systems.

Why Water Needs to be Treated

Water Treatment consists of three crucial factors: Service, Chemistry and Equipment. It is an important part of the preventative maintenance program for boiler, cooling, and process water systems. With the right partner, you can ensure to have a reliable and well-working system that will minimize cost, maximize efficiency and provide sustainable solutions.

Understanding Cycles of Concentration

Evaporative systems are more complex to treat than closed systems. Why? It’s because the solid impurities become increasingly concentrated in the system water during the normal course of operation. Makeup impurities do not typically concentrate in closed systems. In evaporative systems, large quantities of water are used on an ongoing basis. Economics dictate the use of chemicals that can be applied at low dosages. Closed systems normally use only the amount of water required to fill the system one time and any water losses from leaks and repairs.
