An Improved Ash Fusion Test,ility under Standards such as AS1038.15–87 and ASTM D1857–87. However, unlike the standard method the new method produces quantitative results of progressive dimensional changes during heating and melting of the ash. Further, the new method has much improved precision in determination of the tempera

Mechanisms of Ash Fouling during Low-Rank Coal Combustion,s. The coals contained varying levels of alkali and alkaline-earth elements that are commonly associated with initiating and accelerating ash fouling, including Na, Mg, K, Ca, and Fe. Combustion testing revealed that fouling deposits generated from these coals shared common chemical and physical pro
