Following ISG’s analysis, designs included replacement of feedwater pumps and the stack, as well as upgrades of all other related equipment, and gas and oil supply.

The project also included alterations to a 200,000 lb/hr, 1,200 pounds per square inch (psi) coal boiler and new controls for three existing package type oil/gas boilers. New gas/oil guns for the coal boiler, ash handling revisions, and control upgrades, and upgrades to the pollution control equipment were also provided. The boiler had an electrostatic precipitator for pollution control that failed to meet facility emissions standards. The controls and flue gas routing were redesigned to correct existing operational problems. The total project cost was $3.1 million for the gas/oil package boiler, and $1.9 million for the additional coal boiler and distributed control system (DCS) upgrades for a total project cost of $5 million.
