Slag Characterization: Viscosity of Synthetic Coal Slag in Steam
, 1980 A rotating cylinder apparatus has been designed and constructed for measuring the viscosity of molten slags under steam pressure in the range 15 to 300 psi and up to about 1400/sup 0/C. Two synthetic coal slags, one high in alkali and the other lower in alkali but higher in calcia were studied with this apparatus.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In the pulverized coal boiler industry, reducing NOx emissions has become a critical objective. Although low‐NOx combustion technologies are effective, they may lead to localized high‐temperature corrosion. To address this issue, near‐wall air supply technology has been introduced, which involves injecting an appropriate amount of air near the
