5.11 — Lay-up
If the boiler will be out of use for an extended period, precautions must be taken to protect fireside and waterside
surfaces from deterioration due to corrosion.
At the start of lay-up, thoroughly clean the fireside by removing any soot or other products of combustion from the
fireside surfaces. After brushing all surfaces clean, sweep away or vacuum any residue. The fireside may be
flushed with water; however, all surfaces should be completely dried before lay-up.
Dry lay-up
Dry lay-up is generally used when the boiler will be out of service for a lengthy time period, or where the boiler
might be subject to freezing temperatures. The boiler must be thoroughly dried before dry storage, as any moisture
could cause corrosion. Both fireside and waterside surfaces must be cleaned of all scale, deposits, soot, etc. A
desiccant such as quick lime or silica gel should be placed in suitable containers inside the boiler vessel.
Wet lay-up
Wet storage is generally used when a boiler may be needed on short notice or in cases where dry storage is not
practical. Before wet storage the vessel should be drained, thoroughly cleaned, and refilled to overflowing with
treated water. If deaerated water is not available, the unit should be fired to boil the water for a short period of time.
Whichever method of lay-up is used, a periodic re-check of fireside and waterside conditions is recommended
during lay-up.
