When two of Cherokee Generating Station’s coal-fired boilers were being retired and the two remaining units were designated for intermittent use, the facility needed a supplemental heat source, so Xcel Energy installed six new natural-gas-fired auxiliary boilers.
Barr provided detailed engineering services to integrate the new auxiliary boilers purchased by Xcel into the existing building systems. Specifically, we evaluated the existing building and condensate-return pumping system, designed a new structure, prepared general arrangement layouts, designed or modified piping and ventilation systems, developed construction specifications, and provided construction support.
The constrained spaces in the new boiler building and the routing of several pipe systems in the existing power plant presented many design challenges. Barr collaborated with project and plant staff members to identify and resolve the issues successfully.
