Pulverized coal-fired boiler - Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.

Effect of kaolin additive on PM2.5 reduction during ...

Little work has been performed on the importance of sodium and its occurrence in coal to PM 2.5 (particles less than 2.5 μm in aerodynamic diameter) reduction by kaolin during O 2 /N 2 combustion and O 2 /CO 2 combustion at high temperatures. In this study, the combustion experiment of a treated low-sodium coal with sodium aluminosilicate additive was conducted in a lab-scale drop tube ...

Coal mining only became more popular as time went on and people began using chimneys. In 1824, Sadi Carnot published a theory on thermodynamic cycle of the heat engine, which he applied to the development of an engine that relied on pulverized coal. While coal was one of the first focuses of pulverizing equipment, it soon diversified.

Effect of Pulverized Coal Preheating on NOx Reduction ...

Although various NOx removal technologies have been commercialized, NOx emissions are still so high that they cannot meet the newest standard and endanger the eco-environment and human health. Meanwhile, some NOx reduction technologies suffer from high costs. Recently, a cheap and pending technology called gas-fired coal preheating has surfaced again.
