Abstract Thermo Fisher Scientific

Corporation provides minute-by-minute analysis of SiO 2, Al 2 O 3, Fe 2 O 3, CaO, TiO 2, K 2 O, and Na 2 O in the ash. PacifiCorp installed one of these units in its coal yard to blend coals of differing ash composition, in order to keep the blended coal's ash softening temperature above 2175degrees F.

Several coal beds in eastern Kentucky meet the low-ash and sulfur requirements of metallurgical-grade coal feedstock, but unfortunately they typically have volatile matter contents (in the mid to high 30's) that are too high for use in steel production.

Effect of Coal Ash Composition on Ash Fusion Temperatures

Abstract. The ash fusion temperatures (AFTs) of coal mineral matter at high temperature are important parameters for all gasifiers. Experiments have been conducted in which mixtures of selected coal ashes and SiO 2, Al 2 O 3, CaO, Fe 2 O 3, and MgO were subjected to the standard test for ash fusibility.

COAL FLY ASH Material Description. ORIGIN. The fly ash produced from the burning of pulverized coal in a coal-fired boiler is a fine-grained, powdery particulate material that is carried off in the flue gas and usually collected from the flue gas by means of electrostatic precipitators, baghouses, or mechanical collection devices such as cyclones.

Class C materials are often high-calcium (10% to 30% CaO) fly ashes with carbon contents less than 2%. Many Class C ashes when exposed to water will hydrate and harden in less than 45 minutes. Some fly ashes meet both Class F and Class C classifications. Fly ash is used in about 50% of ready mixed concrete (PCA 2000).
