Title: Illinois Power`s on-line Operator Advisory System to control NO{sub x} and improve boiler efficiency: An update

Abstract

At the 1996 American Power Conference, Illinois Power Co. (IPC) and PowerMAX{reg_sign} personnel presented a paper which described boiler tuning at the Hennepin Power Station as an element in the IPC NO{sub x} control strategy to comply with the Clean Air Act amendments of 1990. The paper included the initial optimization of a 235 MW unit and the subsequent plan to integrate the models and software with a Westinghouse WDPF distributed control system (DCS) to enable an on-line Operator Advisory System. The tuning and control solution implemented by IPC is the Ultramax Method{trademark} which utilizes an approach called Dynamic Optimization (DO). This technology makes possible improvements in boiler efficiency and NO{sub x} while constraining other emission and thermal performance parameters to avoid adverse effects. The Operator Advisory System has been implemented and in use since early September 1996. Models of a variety of operating scenarios are being created to advise best control parameter settings as conditions change, and to maintain the significant improvements in both NO{sub x} emissions and boiler efficiency that have been achieved. The models help the operator maintain the best combination of compliant and cost-effective operation. They enable the operator to respond to changing load and fuelmore » conditions, burners out of service, mill conditions and other situations that affect boiler performance. Models are updated daily to reflect the current status of the boiler system. This paper is an update on the development and operation of this advanced system and the value it brings to more effective operation of the generating units at Hennepin. It describes the components of the Operator Advisory System, the operations strategy for effective operator use, and the benefits obtained from the use of the system.« less
