This volume reports experimental and theoretical results of a twenty-six month study of entrained coal gasificaton with steam and oxygen. The gasifier facility and testing methods were revised for improvement in data accuracy. Fourteen tests were conducted in a laboratory gasifier to determine effects of inlet gas composition, temperature and swirl number on carbon conversion. A major increase in carbon conversion was observed with oxygen in the feed stream with the coal. The gasifier facility was also rebuilt for pressures to 250 psi and cold flow tests demonstrated facility operation to the maximum pressure. Sulfur pollutants were measured in eleven additional gasification tests. Methods for sulfur analysis were developed and the accuracy determined. Gasifier tests were also performed to support Los Alamos National Laboratory development of optical methods for analysis of gasifier effluents. A laser-Doppler velocimeter (LDV) was demonstrated for measurement of instantaneous velocity and turbulence intensity in non-reactive flows. Six tests were completed with the LDV system. The one-dimensional coal gasification code (1-DICOG) was upgraded, a revised user's manual prepared (Vol. II) and 133 runs were performed. The two-dimensional coal gasification code was completed (PCGC-2), a user's manual prepared (Vol. III) and several computations performed. Eight technical papers based on results of this study were published or prepared.
