The HOT FOIL ™ LOI Instrument is a
bench-top analyzer that eliminates the long laboratory turn-around times
for ash LOI analysis typically associated with the use of conventional LOI
techniques.
Typical turn-around times of hours are reduced to minutes. LOI data
required for boiler tuning can now be generated in near real-time to
optimize mill, burner, and OFA damper adjustments for good carbon burnout.
In addition, the instrument can be used to monitor and control fly ash LOI
for ash sales and disposal.
A small quantity of collected ash sample is placed in a foil “boat” and
heated with electric current; the associated weight loss in the ash sample
is equivalent to the LOI.
