Rochdale Power Plant is a 21 MW facility that generates all the electrical power, heating, air conditioning, and hot water for a residential co-op and two shopping malls.

Repowering Project for Package Boilers – Redesign & Retubing

Helfrich Brothers Boiler Works was selected as the EPC for the repowering project. Three of the four package boilers were completely retubed with many furnace design changes implemented. A fifth unit was added to the plant as part of the repower project.

The Challenges

The original boilers went into operation in approximately 1963.

The Solution

HBBW Engineering redesigned the superheater casing and rear walls. Thermal and Stress Analyses were performed to confirm redesign. New CAD drawings for shop fabrication and field installation were created. HBBW procured the materials required and fabricated all parts necessary in their 95,000 SF shop.

The Results

Fabricated tubes and parts were shipped to the field. Complete retubing of each boiler, superheater, and economizer was required. Only steam and mud drums remained after a complete inspection and assessment. Field services completed the demolition and installation. Once complete the outside was insulated and covered with lagging for protection.

“HBBW was the perfect choice as EPC for our repowering project. They had all the expertise and knowledge in-house and were able to engineer, fabricate, and provide on-site installation services to complete on this project on-time and safely.” – Project Manager
