Partner Profile
The new Central Heating Plant (CHP) will be located adjacent to the Amherst Wastewater Treatment Facility at the north end of Mullins Way on the University of Massachusetts Amherst campus. The CHP is being financed by the University of Massachusetts Building Authority and is currently in design and permitting. It is scheduled to begin start-up operations in the fall of 2003. The CHP includes a 10-megawatt gas turbine producing electricity at 13.8 kilovolts for on-campus consumption. A 100,000-pound per hour, auxiliary duct-fired, heat recovery steam generator (HRSG) will use the exhaust heat from the gas turbine to produce steam for campus heating year-round. Three conventionally-fired package boilers, each rated at 175,000 pounds per hour of steam, will provide additional capacity to meet campus steam demand in the spring, fall, and winter. Two large diameter main steam lines and a pressurized condensate return line will connect the CHP with existing campus distribution systems. These lines are capable of carrying both low and intermediate pressure steam. The CHP will burn natural gas and transportation grade, No. 2 fuel oil. The HRSG could be designed as a high-pressure (600 psi) boiler to provide steam to a back pressure steam turbine generator. The back pressure steam turbine could extract one-third of its steam at 90 psi and two-thirds of its steam at 20 psi to match the average campus demand (peak summer) between the intermediate and low pressure steam distribution systems. The electric output would follow the steam demand.
