Notes:
1)
These recommendations are reasonable for typical fire-tube boilers (CB,
Kewanee, Superior,
York Shipley, and Johnston). Use the
higher-end recommendation for long-term lay-up and/or for the higher-end horse power
range.
2) Due to various
water-tube boiler designs and configurations, you will need to get the information on a case by case basis.
3) In fire-tube boilers
blow in the dry powder so it is spread out horizontally along the belly. In
water-tube boilers blow in the dry powder so it is spread out vertically
(i.e., mud drum
and steam drum). This will optimize
distribution of VCIs.
