A Cloud With a Silver Lining: The Killer Smog in Donora, 1948

There had been claims settled against the mill in the early 1900s. The first claim came from Mamie C. Burkhardt and her husband, Frank, after they started to see the health and environmental effects of the steel mills. The mills' nine smokestacks blew copper-colored dust towards the Burkhardt house.

Observer-based fault detection and moisture estimating in

The temperatures of the primary air and pulverized coal flow are used to control the temperature in the coal mill at the classifier. The temperature controller is required to keep the temperature at 100 ∘ C in the mill in order to ensure that the moisture in the coal evaporates. A coal mill is a harsh environment to perform measurements in

Southern company tests of wood/coal cofiring in pulverized

A coal-only test (Test 9) was conducted between the two days of wood/coal firing. Fineness samples from the mills for this test were nearly identical with those from the earlier coal tests preceding the wood cofiring. Wood/coal mixture grinding required more mill power than did coal alone. Mill amps cofiring wood were about 10-15% higher

Kiln vs flash calciner

The kiln system provides the gradual heating and extended retention time (normally ~30 minutes) needed to effect the conversion on large particles. Conversely, a gas suspension calciner (GSC) is best suited for spodumene concentrate that has a PSD less than 1mm, which is common for concentrates produced via the floatation process.
