Title: Illinois Power's online dynamic optimization of cyclone boilers for efficiency and emissions improvement

Illinois Power Company (IP) is a leader in implementing online dynamic optimization at its fossil-fired power stations. As part of the company's Phase II CAAA compliance plan, IP proceeded with similar online systems at its Baldwin, Wood River, Havana, and Vermilion stations for all 10 of its coal-fired units. These Operator Advisory Systems utilize the Ultramax Method{trademark} and Dynamic Optimization, known as ULTRAMAX{reg{underscore}sign}. Of particular interest are the installations on Baldwin Units 1 and 2, which are 575 MW B and W cyclone units. Throughout the power generation industry, there has been great concern about how to deal with high NO{sub x} levels and meet EPA regulations while avoiding excessive capital costs. Based on previous applications of ULTRAMAX to cyclone units, a successful control strategy was employed for optimization of the Baldwin cyclones. These empirical model structures were then integrated with Baldwin's Distributed Control System (DCS), a Westinghouse WDPF interfaced with an Oil Systems Plant Information System (PI), to provide continuous online optimization. The online optimization system meets IP's objectives of NO{sub x} reduction and concurrent improvement in boiler efficiency. IP benefits by achieving compliance with emission regulations while securing cost savings and a rapid return on investment. Implementing ULTRAMAXmore » as an integrated online solution on the Baldwin cyclone boilers, as well as Unit 3, a 595 MW ABB-CE tangential unit, assists the operator when conditions change, simplifies data collection and enables daily updating of boiler models. This continuous use of an integrated dynamic solution offers the opportunity for greater emissions control, fuel savings, and the ability to respond rapidly and flexibly to changes in operating conditions, compliance regulations and the market environment.« less
