A gas reburning system, to demonstrate the economic and technical viability of the technology as a means of reducing emissions of oxides of nitrogen, has been installed on a 600 Mwe coal fired boiler at Longannet Power Station, owned and operated by ScottishPower. The Project, which was awarded a grant under the European Commissions THERMIE Programme, is being undertaken by ScottishPower in conjunction with a number of European partners, namely: British Gas, ESB, ENEL, Ansaldo Energia, EDF and Mitsui Babcock Energy. The project commenced in August 1994, when the participating partners began the process design. This included the definition of the number and location of the gas injectors, overfire air ports; specification of the associated process conditions for overfire air, recirculated flue gas and process gas; and the control system philosophy. Installation of the reburn equipment commenced in December 1995, and was completed in October 1996. Following commissioning in late 1996, a comprehensive testing program was undertaken with the objectives of optimizing reburn performance and validating the process design methodology. This paper describers the background and scope of the project, including the use and development of in-house experimental and theoretical modeling used in the process design, and reports on the progress and results obtained to date from the testing program.
