Purdue University, Duke Energy Combined Heat and Power Facility
West Lafayette, IN
ICT was responsible for the design of a new Combined Heat and Power (CHP) plant. The power generated from the system will be directed to the utility’s distribution system, and the steam will be sold to a thermal host located adjacent to the site.
The CHP system consists of a 15.5 MW combustion turbine generator, a Heat Recovery Steam Generator (HRSG), and a duct burner to increase the production of steam. The HRSG is capable of producing 150,000 lb/hr of superheated steam at 600 psig and 775°F. The system is configured with a diverter damper and bypass stack, to allow the generation of power independent of steam generation when necessary. The CHP system is housed in a new building which includes offices, restrooms/lockers, a breakroom, control room, IT room, low voltage and medium voltage switchgear rooms to support CHP operations. The plant also includes a fuel compression system to increase the natural gas supply pressure to 400 psig; a 100,000 gallon condensate storage tank; a new deaerator and boiler feed-water pumps; and is connected to the thermal host’s existing auxiliary systems for condensate return and make-up water.
