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.
