Central Mode Particulate Matter Control by ... - SpringerLink

The detailed process of central mode particulate matter (PM) control under the condition of blended coal combustion was studied. Blended coal combustion and mineral heating experiments were carried out in a drop tube furnace at 1373 and 1573 K. The two parent coals were, respectively, rich in Ca/Fe minerals and aluminosilicates.

Role of Minerals in the Evolution of Fine Particulate ...

In this paper, the pulverized coal combustion was conducted in a 25 kW quasi one-dimensional down-fired furnace to examine the role of minerals in the evolution of fine particulate matter (PM) along the axial length of the combustor. The fine PM, emitted at different stages of coal combustion, was collected with a nitrogen-aspirated, isokinetic particulate sampling probe and classified in size ...

Minerals of Alabama | Encyclopedia of Alabama

When pulverized and mixed with water, clay forms a mass that can be molded and that hardens when heated to a high temperature, called firing. The earliest commercial use of clay mineral deposits in Alabama was by British settlers in 1780 for making bricks, tiles, and pottery in Mobile. Historically, clay deposits along the eastern shore of ...
