This volume is the last of a three volume set. Specifically, the activities reported herein cover investigations on the problem of determining NO yields from pulverized coal flames. Work also focused on several approaches to reducing NO in combustion products. The work is described in the following sections. Homogenous Kinetics: This task seeks to improve and update a model describing homogenous fuel nitrogen reactions. The specific focus is reburning, although all fuel chemistry (through C{sub 2} hydrocarbons) is considered. Nitrogen species include HCN, N{sub 2}O, NH{sub 3}, NO{sub x}, and all the relevant intermediates. Heterogenous Reduction: This project was designed to measure the rate of NO reduction on soot so that the importance of the heterogenous pathway could be quantitatively determined. Fuel-Nitrogen Reactions in Pulverized Coal Combustion: This project is designed to provide a bridge between the more fundamental elements of the program. The goal is to develop global data against which the more fundamental models can be compared. Nitrous Oxide Behavior: This section describes the development of an analytical method for measuring nitrous oxide in flue gases. It also describes the discovery of a major sampling artifact in which N{sub 2}O is produced with containers that are commonly used for grab samples. Post-Flame NO{sub x} Reduction Agents: This project focused on the detailed kinetics of the reduction of NO by cyanuric acid. The study also focused on the promotion of the reaction by CO. 3 refs., 34 figs., 4 tabs.
