Coal ash mineral elements content detection detects moisture detection Chen: 18028719379 Coal is ancient plant buried in the ground through the solid flammable mineral complex biochemical and physical and chemical changes gradually formed. Is a solid combustible organic rock, mainly from plant remains through biochemical, buried and then change made by geological, commonly known as coal. Coal was hailed as black gold, the food industry, which is one of the main energy sources since the eighteenth century, the use of the human world. According to test results, an overview of the coal organic matter content and low calorific value, which initially determine the type of coal, processing and utilization of results and industrial uses. Detection range of coal, coal, coal washing, screening coal, low-quality coal. Test items coal routine analysis: moisture, ash, volatile matter, fixed carbon; coal elemental analysis: carbon, hydrogen, nitrogen, sulfur, cadmium, chromium, lead, mercury; ash analysis: silicon, iron, titanium, aluminum, calcium, magnesium, sulfur, phosphorus; coal index analysis: ash fusion, slag carbon content, caking index, grindability index, glial layer thickness, density, particle size, such as the quality of the screening test items. Equipment atomic absorption spectrophotometer, Coulomb Sulphur, heated oven, muffle furnace, equality days.
