It's probably a good idea to have them attend a professional steam and hot water training seminar. These programs provide a window into elements of the plant steam cycle as they observe live steam and condensate behavior in glass piping and glass-bodied steam traps under differing conditions. They gain very useful knowledge regarding:
- Steam generation
- Distribution
- Control & Heat transfer
- Heat Recovery opportunities
- Condensate removal & return
Mead O'Brien, a company with decades of experience in industrial and commercial steam and hot water systems provides such training. See their video below:
