A COMPARISON OF NOX LEVELS FROM R-AND-D STUDIES WITH VALUES MEASURED AT DIFFERENT PLANTS

For engineering design considerations, it is essential to correlate ad equately the results obtained from R&D with those from commercial plan ts, so that the effect of scaling-up can efficiently be taken into acc ount in predicting NOx levels when designing large combustion equipmen t to be employed in different end-use applications. INETI has very rec ently started compiling both R&D and field data on NOx emissions resul ting from coal combustion. The eventual objective of this work is to e stablish an empirical correlation for coal burning equipment to relate NOx levels from R&D work with those observed in full scale industrial units. Such a correlation, if derived, could successfully be employed in simulation models used for design.
