Fired heaters — an open flame next to a hydrocarbon inventory
How a furnace is arranged, why the process fluid and flue gas travel in opposite directions, what draught and excess air actually control, and why the purge before light-off is never negotiable.
Vessels, exchangers and relief devices — the static equipment
What MAWP means and why it matters more than design pressure, how heat exchanger types differ, and why the relief device is the one protection that cannot be bypassed.
Pumps — head, NPSH and why cavitation is a suction problem
Centrifugal versus positive displacement, what a pump curve tells you, why NPSH decides whether a pump survives, and why most pump failures are really piping failures.
