Anthracite (English name anthracite), commonly known as anthracite or red coal. Is the largest coal rank coal. High anthracite fixed carbon content, the volatile low yield, density, hardness, high-lighted, no smoke when burned. Hard, black, metallic luster. Friction to fat without the pollution, to fracture into shelly shape, the combustion flame is shorter and less smoke. Not coke. The average carbon content of more than 90%, volatile matter at 10% or less. No gelatinous layer thickness. The calorific value of approximately 8000-8500 kcal / kg. Sometimes volatile matter content oversized called semi-anthracite; called a special small anthracite. Anthracite: Item Index fragmentation rate + wear rate /% ≤ 3 anthracite density / g · cm 31.4 to 1.6 with mud content /% ≤ 4 hydrochloric acid capacity rate /% ≤ 3.5 density greater than 1.8g/cm3 content /% ≤ 8 capsules the diameter range / mm0.8 ~ 1.8 (double-layer); 0.8 to 1.6 (three) particle size is less than the lower limit of the particle /% ≤ 3 particle size is greater than the upper limit of particle /% ≤ 2 anthracite uses: for students including water supply and industrial The feed water filtration and purification process.
