Nice @Papabuy
Mobile (Marine) type here.
Mainly 2 Drum economisier and superheated 450C and 550psi for 23,000KW.
The "proper" destroyers worked at 1200psi to give 52,000KW.
That gets a 4,500 tonne ship along at nearly 65km/hr at a diesel burn rate that is eye watering.
(apologies for mixing units in that)
