Freezing conditions
pose a huge risk to boiler equipment if it is not properly protected from the
harsh elements. In order to ensure that your unit continues to operate while
facing freezing conditions, Nationwide Boiler recommends the following:
1. Enclose both the front and rear of the boiler area and use an
external heat source to minimize freezing conditions.
2. Install heat tracing with insulation to protect exposed stagnant
water lines.
3. Utilize an appropriate heat tracing method (electric or steam
tracing) to all of your main lines and piping components. This includes the
following lines which should be heat traced regardless if the boiler is in
operation or not (in freezing conditions): sensing lines (steam drum to CMR,
high steam and steam gauge), auxiliary low-water-cut-off, water column and
level control blowdown. Depending on the length of piping runs, the main and
continuous blowdown should also be heat traced.
4. In addition to heat tracing on stagnant sensing lines, drain the
lines and fill them with a 50/50 (water/glycol) solution, making sure to
re-connect the line.
5. When an extended boiler down time is expected, completely drain
the boiler and stagnant water lines.
