The UNC Cogeneration Facility is one of
the most modern energy production facilities of its kind and has been
nationally recognized throughout the years for its accomplishments and
superior environmental performance.
The primary purpose of the central
plants is to generate and distribute steam which is used for heating,
humidification, domestic hot water heating, sterilization and making
distilled water. During the cogeneration process, the steam passes
through a 34 MVA double automatic controlled extraction pressure
and condensing steam turbine generator. As a result, up to one-third of
the electricity used on campus can be produced as a byproduct. This
combination results in an overall thermal efficiency of twice that of
any plant built solely for the purpose of power generation.
In addition to maximizing energy
efficiency, cogeneration signigicantly minimizes the impact to the
environment. Coal, the most plentiful and economical fuel
available, is used primarily; however gas and fuel oil can be used as
backup. The facility relies on advanced technology called
circulating fluidized bed (CFB) and continuous air emissions monitoring
equipment ensures compliance with all State and Federal air quality
regulations
