U.S. coal exports declined in 2019 - Today in Energy - U.S

U.S. steam coal exports were affected by the downturn in global coal demand, dropping 30% in 2019 from 2018. Metallurgical coal had a more moderate decline of 10%. Steam coal, also known as thermal coal, is used for electricity generation. Steam coal is ground into a fine powder that burns quickly at high heat.

IMR-4064 Powder Temp Sensitive or Not ? | Shooters' Forum

Used IMR 4064 for years in the 22 250, 243, and 308 and never found it to be any more "temperature" sensitive than other "stick" powders. The only powder that I encountered that was truly temperature sensitive meaning pressure surges in hot weather was H380 in the 22 250. I had to scale back the powder charge about 1 grain.

Coal dust - Wikipedia

Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal.It is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.

Powder River Basin coal production drops more than 9% YOY

The Powder River Basin is the largest source of coal in the U.S., primarily producing thermal coal used for power generation. Unlike eastern U.S. producers, the region has limited economic export opportunities, even when global coal prices are high. Coal production from the area slid about 10.6% from the third quarter to the fourth quarter of 2019.
