Book Description
With the enactment of the Clean Air Act Amendments of 1990, there is now additional incentive for the development of gas turbine systems with very low NO(subscript x) emissions characteristics. Further, the development of low NO(subscript x) burners that are capable of utilizing low-heating-value gases derived from coal based systems is an essential component for a number of fossil energy technologies including IGCC and second-generation PFBC. However, the chemistry associated with NO(subscript x) formation is complicated, and attempts to reduce these emissions often result in increases in other undesirable species such as CO or N2O. In view of these complexities, it is useful to study NO(subscript x) formation and NO(subscript x) control strategies in a well-controlled, lab-scale burner system. In this way, detailed knowledge about the intricate interrelationships between the various chemical pathways can be obtained and subsequently applied to bench-scale and larger systems. The current project involves both chemical kinetic modeling as well as experimental studies performed in a premixed burner system to generate these data.

Book Description
The overall objectives of the research at Purdue are to: obtain a reduced mechanism description of high pressure NO formation chemistry using experiments and calculations for laminar lean premixed methane air flames, develop a statistical model of turbulence NO chemistry interactions using a Bunsen type jet flame, and utilize the high pressure chemistry and turbulence models in a commercial design code, then evaluate its predictions using data from an analog gas turbine combustor. Work to date has resulted in the following achievements: spatially resolved measurements of NO in high-pressure high-temperature flat flames, plus evaluation of the influence of flame radiation on the measured temperature profile; measurements of temperature and velocity PDFs for a turbulent methane/air flame were obtained for the first time, under operating conditions which allow their study in the distributed regimes, and the increase in EINO(subscript x) with equivalence ratio predicted using a chemical kinetics model; and simulation of non-reacting combustor flow fields from ambient to elevated pressure and temperature conditions and comparison of those results with experimental velocity profiles.
