Abstract
Gieseler plastometer tests were performed on eight western coking coals
at retort - immersion depths ranging from 2 to 3-3 /4 inches (measured to the
center of the coal charge ) . Increased maximum fluidities were associated with
greater retort - immersion depths , the most pronounced increases being observed
on highly swelling coals when tested at 3-3 /4 inches . The maximum fluidity of
one of these coals when tested at 3-3 /4 inches was 146 percent greater than
that observed at 24 inches .
Retort - immersion depth had no significant effect on the temperatures of
initial softening , fusion , maximum fluidity , end of fusion , and solidification .
