2 EXHAUST SYSTEMS WITH SILENCERS
August 2015 - April 2016
Wolverine Power Supply Cooperative
Alpine Power Plant - Gaylord, MI
Moran Iron Works was awarded the contract to supply design, engineering, fabrication, and installation of two exhaust systems for Wolverine Power. The exhaust systems were installed at Wolverine’s Alpine Power Plant located in Elmira Township near Gaylord, Michigan. The plant utilizes two General Electric Frame 7FA.05 turbines for natural gas to generate over 430 megawatts of nameplate electricity.
MIW’s exhaust system design employed noise abatement guidelines and resulted in two of the most efficient exhaust systems in use. The systems required approximately 800 tons of steel to construct.
FRAME 7B DIFFUSER
March 2015 - September 2015
Moran Iron Works was awarded a contract to fabricate a replacement diffuser assembly for install at Universal AET’s customer.
This unit was fabricated using 304H, high carbon stainless steel, for durability in the extreme heat of a Frame 7B exhaust. Machined flanges to hold tight tolerances and shipped direct to the project site.
SILENCER & TRANSITION FABRICATION, PLENUM REPAIRS
Moran Iron Works was awarded the contract to fabricate and deliver a new Frame 5 silencer. The work also included demo of the old silencer unit and installation of the newly fabricated one.
This unit was shipped via oversized load to Stock Key / Key West in one piece with lifting lugs installed for both rolling and lifting. Plenum repairs were also required due to years of degradation in the salt water environment.

FRAME 5 SILENCER & TRANSITION
Moran Iron Works was awarded the contract to fabricate a complex silencer and plenum heat shields for a 40 plus year old Frame 5 unit. This silencer stack had three levels of baffles for maximum performance. The plenum heat shields were replaced due to age and replacements were installed without the removal of the diffuser.
This unit was shipped via oversized load to Douglas in one piece with lifting lugs installed for both rolling and lifting.
The project was completed and delivered in three months.
