Packaged Boiler Project

J.R. Johnson Engineering provided engineering services for the installation of five (5) 80,000 PPH packaged steam water tube boilers and associated equipment at an aging steel mill powerhouse. The project included equipment layout and engineering for (5) boilers, (3) deaerator tanks, (5) duplex water softener and brine systems, (8) chemical feed systems and (2) blowdown heat recovery units.

Stress analysis was performed for all steam and boiler feed water piping, including an analysis of the existing steam main at the tie-in to the mills’ main steam distribution system. The civil/structural work included equipment foundations, pipe support towers and pipe support bents. Electrical general arrangements were developed, in addition to single line diagrams, lighting and grounding plans.
