Phase IV Energy Efficiency Improvements

client:

Buffalo State, State University of New York and New York Power Authority (NYPA)

location:

Buffalo, New York

Project Objective
In order to supply the campus with hot water during the summer months, Buffalo State College had to operate its central high-pressure steam system. The goal of this project was to provide summer domestic hot water, while reducing the energy consumption and stack emissions created by the use of #6 fuel oil.

Solution
An 800-horsepower fire tube boiler was installed along with four 50,000-pound per hour, brick set, water tube boilers. The new boiler serves the summertime steam load and allows the use of a water tube boiler to meet base load requirements while responding to demand beyond base load during winter operation. A new plant master control system was also installed to improve the operation of the existing water tube boilers and the facility. In addition to the boiler and control upgrades, the project included:

- Boiler Excess Oxygen Controls
- Stack Economizer installation
- Variable speed boiler feed water controls
  and pumping
- Boiler flame management and safety
  controls on the existing four boilers
- Expansion of Energy Management System
  (EMS)
- Installation of heat recovery units for
  Science Building ventilation systems

The project was completed in September 2002.
