UHB Generator Stack Modifications

1. Provide assessment of structural supports for existing generator stacks to determine if modifications are required to adequately support modified/extended stacks. Provide any required structural support enhancements. 2. Provide calculations regarding static pressure requirements for exhaust stacks, based on information from Caterpillar regarding the current generators, to determine if proposed modifications to stack terminations are possible without compromising generator performance or requiring additional controls/axial booster fans/etc. Provide any required modifications identified to ensure generator performance remains within specifications. 3. Provide assessment of existing stack insulation to determine that it has not been compromised over the years of service. Provide any required repairs to existing riser stack insulation and provide required insulation for new terminal sections. 4. Design, furnish and install required stack termination details to remove goosenecks and extend stacks straight up 6 feet as required. 5.
