Coal production in the Donets Basin rose from 1,018,000,000 poods (1 pood = 16.38 kg) in 1910 to 1,550,000,000 poods in 1913. The output of cast iron and steel increased, and new enterprises were established. As the labor movement gained strength, the number of striking workers rose from about 10,000 in 1909 to 15,000 in 1911 and 132,000 in 1912. Political strikes took place

Coal Ash Hazardous to Human Health

Coal ash is the waste that is left after coal is combusted (burned). It includes fly ash (fine powdery particles that are carried up the smoke stack and captured by pollution control devices) as well as coarser materials that fall to the bottom of the furnace. Most coal ash comes from coal-fired electric power plants. Why is it dangerous? Depending on where the coal was mined,

Concrete vs Cement: What's The Difference?

10/01/2020Coal, natural gas, fuel oil, and petroleum coke are often used for firings. Sintering is when the chemical bonds of the raw meal are broken down through heat, recombining into new compounds that form a substance called clinker. Clinker comes out of the kiln as extremely hot, small, dark gray nodules 1mm to 25mm in size.

How Cement Is Made

At the lower end is a roaring blast of flame, produced by precisely controlled burning of powdered coal, oil, alternative fuels, or gas under forced draft. As the material moves through the kiln, certain elements are driven off in the form of gases. The remaining elements unite to form a new substance called clinker. Clinker comes out of the kiln as grey balls, about the size of marbles
