Data acquisition system for sorbent injection test program at Virginia Power Yorktown Power Station Unit 2
- Yorktown Power Station, Yorktown, VA (United States)
- Combustion Engineering, Inc., Windsor, CT (United States)
Virginia Power has installed an ABB Boiler Performance Optimization System (BPOS) at their Yorktown Power Station Unit 2, in conjunction with an in-furnace, sorbent injection, sulfur dioxide emissions reduction test program., This system was selected as offering lower cost and long-term benefits to the station than using dedicated test equipment and personnel for the test program. In addition to providing data acquisition and storage functions for characterization of the effect of sorbent injection on boiler performance, sorbent injection equipment performance, and emissions reduction, the system performs on-line plant heat rate and controllable losses calculations. The BPOS included the following advanced features: (1) Access to test and operating results for station operators, station engineering staff and sorbent injection project staff at their own work spaces at the station and at remote locations. (2) Boiler section surface cleanliness models to aid the boiler operators with soot blowing and to assess the impact of sorbent injection on individual boiler surfaces. (3) Interfaces to the station`s distributed control system (DCS), the sorbent injection system`s programmable logic controller (PLC), and to a data logger used for test instrumentation. (4) Model-based calculations for sorbent injection system control setpoints implemented in BPOS computer system. (5) On-line continuous calculation of sorbent injection system performance indices.
