Graycor Industrial recently completed a major Air Quality Control System (AQCS) project for NIPSCO at its Michigan City Generating Station, a coal-fired electric generating plant which now upgraded with air quality equipment to further reduce emissions. The dry flue gas desulfurization (DFGD) project included installation of two Babcock Power-designed baghouses and dry scrubber trains along with all auxiliary and BOP equipment. Scope also included installation of ductwork, modifications of two Howden axial-type ID fans, replacement of existing waste ash silo equipment, a new waste ash silo, all piping, in-line instrumentation, structural steel, siding and HVAC.
Unique aspects of the project included fabrication area being located approximately 20 miles from the main construction site, which required Graycor’s team to closely coordinate the transport, loading and shipping by barge the assembled components to the construction site. Challenges also included staging and storage of material within a small site which makes assembly critical. To help with this, Graycor worked with the Owner’s vendors on constructability of project as well as delivery of equipment and material.
