2 topics across all disciplines.
Plant utilities — steam, air, nitrogen and cooling water
Why the steam header pressures are what they are, what a steam trap actually does and how it fails, why instrument air and plant air must never share a header, and the reason nitrogen kills more people on plants than almost anything else.
Steam and gas turbines — why the driver is chosen before the machine
Why a turbine is chosen over a motor, what governing and overspeed protection actually do, the difference between back-pressure and condensing steam turbines, and why the first minute of a start-up is the dangerous one.
