EMISSHIELD is a NASA licensed high emissivity ceramic material refined and
patented by Emisshield, Inc in collaboration with Virginia Tech. It has been
designed to save fuel costs and increase productivity in industrial heating
applications. Use of Emisshield extends the service life of equipment and
improves performance as well.
A refractory installer wanted to improve the performance of a ladle cover used to dry out
refractory castable-lined steel ladles.
Emisshield ST-2 (US Patent 6,921,431) was applied to the ladle cover
refractory. A gas burner was placed at the middle of the castable-lined cover
and fuel usage closely monitored.
After the application of the Emisshield high emissivity coating to the ladle cover, a
40-hour dry out schedule was carried out to replace the working lining and the
barrel. This schedule ensured that adequate time was provided to remove water
from both refractories. The cover’s coating significantly reduced the energy
lost through the cover. Using this schedule, the amount of fuel required for
drying out ladles was reduced by 11.5%.
When only the working lining had to be replaced, a 32-hour schedule was
followed. Using a Emisshield coated ladle cover decreased the energy needed to run this
shorter schedule by 21.3%. This increased fuel savings achieved with the shorter
dry out schedule was due to the fact that the ladle cover refractory now had
less chance to absorb heat energy.
