 The
primary focus of this course is on Packaged Boilers but the fundamental
principles apply equally to larger site-erected utility boilers.
As
well as providing entry-level training, when studied together with the
companion course "Packaged Boiler Operation", it is an
appropriate resource for trainee operators in larger installations and
for experienced operators in small plants who wish to achieve formal
certification. |
