Effects of coal structure on pulverized coal combustion processes: Quarterly technical progress report No. 6 for the period January 1, 1987 to 31 March 1987

Technical Report ·
OSTI ID:6635248
Nitrogen BET surface area measurements were completed for the size-graded fractions of Wyoming subbituminous and North Dakota lignite coals. Carbon dioxide DP surface area was determined for the -200 +230 mesh fraction of the North Dakota lignite coal. Gas chromatography data for the extract liquid from the Wyoming subbituminous coal are given. The polycyclic aromatic groups found were mainly naphthalene derivatives and partially aromatized derivitives of pentacycle triterpanes. Analysis of the coded-aperature to enable measurement of particles down to 20 microns is reported. Plans are also presented for the following quarterly period. 10 refs., 3 figs., 2 tabs.
