Lignite, also known as wood coal, coal rank lowest mineral coal. A cross between brown peat and bituminous coals, dull lower coal. Because it is rich in volatiles, it is easy to burn and smoke. We can clearly see the traces of the original wooden cross section. Containing lye dissolved humic acid inside. Carbon content of 60% to 77% of small bean dregs dryer, a density of about 1.1-1.2 dregs dryer, volatile content greater than 40%. No glial layer thickness. Calorific value of about 23.0-27.2 MJ / kg (5500-6500 kcal / kg). Mostly brown or dark brown, the relative density of 1.2 to 1.45. With increasing environmental awareness, China's coal-fired power plant emissions of sulfur dioxide in flue gas increasingly tight control, power plant desulfurization is imperative. Currently gypsum processing technology and equipment is not entirely the same as natural gypsum, such as material handling, dust treatment, calcination process and other: on the physical properties of natural gypsum and gypsum also have differences, such as gypsum of high purity, free water large , fine granularity; uniform particle size particle size distribution, grading poor standard thick water consumption, including water-soluble salts more; also worth noting that both gypsum and natural gypsum from different sources Okara dryer manufacturers, gypsum The unreacted calcium carbonate as the main impurities and calcium sulfite exist not completely oxidized, impurity state difference between the larger, the other in a different production process technology desulfurization process, the different components of the raw materials limestone, limestone fineness of different processing It will affect the quality of Gypsum.
