Plant monitoring and the images above from the
early phases of the trial revealed that the slag for-
mation was minimal and was being effectively re-
moved by the sootblowers. Lakeland and GE
continued to monitor and report on slag formation,
and GE continued to photograph the Unit at these
ports and report the finding after each inspection.
Operator log sheets were completed, which helped
the trial team understand variations in slag condi-
tions day to day.
The superheat section remained clean during the
trial, although sootblower frequency was increased
slightly at the beginning. Tube wall conditions re-
mained acceptable throughout the trial, although
more slag was observed in the furnace during the
opportunity coal burns.
