Heating Plant Rebuild | Project Profile
About the Client
The client for this project is a four-year University located in the upper-Midwest looking improve the performance of its heating plant serving its campus.
Scope of Project
The scope included evaluation of the existing 64,000-ton campus chilled water system dispatched from three plants and upgrades to the 26,000-ton heating plan for enhancing system efficiencies and water use. Other effort involved determining the increase capacity to meet future demand curves, modifying chiller equipment drives, sizing and determining type of steam turbine generators (STGs), balancing loads, partial upgrading of chiller capacity and partial replacement of electric chillers, thermal storage, and chiller water pumping equipment.

Results delivered to client
Project challenges included working on the main campus of a dense big ten university with an aging infrastructure and increasing utility demands for chilled water, electricity and steam.The program also included a new 350,000 pound/hour biomass boiler with expansion plans for a second such boiler. This future boiler will be housed separately from the existing boilers requiring the construction of a new building, added emission controls and necessary distribution systems. Two newSTGs with capacities in the range of 22 -27 MW will require the construction of a new turbine building to house them along with two relocated STGs and an experimental turbine developed by the University.The power generated from the STGs will feed anew electric substation to serve an expanded underground campus distribution system.
