Nitrous oxide emissions. Topical report, July 1, 1990--June 30, 1993
Published N{sub 2}O emissions data for experimental studies examining large numbers of coals are generally scarce at the pilot-scale fluidized-bed combustion (FBC) level, although some data are available at the laboratory scale. The primary objective of this study was to determine the atmospheric contribution of N{sub 2}O derived from coal combustion. Additionally, the goal was to establish a comprehensive engineering model to assist in the prediction of N{sub 2}O emissions based upon operating and design considerations. To meet the overall objectives of determining the overall contribution of N{sub 2}O derived from FBC and developing an engineering model seven tasks were originally proposed. The objective of each task as originally proposed and finally executed is presented in this topical report. The seven tasks were: (1) literature survey; (2) equipment design and test plan development; (3) experimental techniques; (4) pilot-scale determination of the impacts of coal properties and operating conditions on N{sub 2}O emissions; (5) role of coal char on N{sub 2}O formation and destruction; (6) homogeneous versus heterogeneous reactions; and (7) modeling of N{sub 2}O emissions.
