Effects of coal structure on pulverized coal combustion processes: Quarterly technical progress report No. 5 for the period September 1, 1986 to 31 December 1986

Technical Report ·
OSTI ID:6956145
The general objective of this study is to define and quantify the relationships between coal composition and the structure and associated combustion and conversion behavior for three very different domestic coals of interest. During this past quarter, nitrogen BET surface area was measured for the size-graded fractions of Wyoming subbituminous and North Dakota lignite coals. Preliminary tests of the temperature programmed reaction method were conducted. Design of a pyrolysis reactor is given. The tungsten ribbon lamp to be used for calibrating the optical pyrometer system was calibrated for temperature as a function of input voltage. The measured temperatures were corrected for the non-blackbody behavior of tungsten. Design of a coded-aperature to enable measurement of particles down to 20 microns is given. Plans are also presented for the following quarterly period. 15 refs., 4 figs., 1 tab.
