Abstract: A hardware-adaptable data visualization tool for use in visualizing data from a data source, including: a data source module, for providing a numerical data set representing aspects of data to be interpreted; and a viewer module, responsive to the numerical data, for providing a view of the numerical data set, such as a fully immersive view or a more limited view, helpful to a user in interpreting the numerical data set; wherein the viewer module in turn comprises a set of component modules, and wherein the source module and the viewer component modules are compiled and linked together into one or more executable files depending on factors including the performance capabilities of a predetermined target host or hosts as well as the desired utility of the executable files, the component modules having programming interfaces that are substantially independent of the predetermined target host or hosts.

Abstract: Reduction of nitrogen oxides emissions from large scale combustors, such as coal-fired boilers and incinerators which produce effluents with high solids concentrations, is improved. High solids loading and other operational factors can cause such large temperature gradients transverse to the direction of effluent flow that SNCR cannot be practiced in conventional fashion. The process entails defining a near-wall zone having a temperature effective for SNCR and a central zone where the temperature is too high. NOx-reducing composition is introduced into the effluent within the near-wall zone in fine droplets, and can be introduced into the central zone after the gases have cooled or as large droplets effective to survive the high temperatures.

Abstract: Reduction of slagging is improved by targeting slag-reducing chemicals in a furnace with the aid of computational fluid dynamic modeling. Chemical utilization and boiler maintenance are improved.

Abstract: Nitrogen oxides are reduced in gas turbines by selective, gas-phase reaction with urea. This is enabled in a preferred embodiment by injecting urea as an aqueous solution of droplet sizes and concentration effective to assure selective gas phase reactions to result in NO.sub.x reduction. The aqueous solution can also be employed to reduce NO.sub.x by reducing the flame temperature. Desirably, the injection parameters are controlled to also minimize ammonia production.
