    Coal gangue has heat, generally at 1500 kcal.

    Coal gangue is divided into clay rock, sandstone rock, carbonate and aluminous rock according to the main mineral content. According to the first and final state, coal gangue can be divided into three categories: tunneling gangue, coal preparation gangue and natural gangue.

    The discharge of coal gangue varies greatly according to the different coal seam conditions, mining conditions and washing processes, generally the excavation gangue accounts for about 10% of the raw coal output, and the coal preparation gangue accounts for 12% and 18% of the selected raw coal.

    The inorganic components of gangue are mainly oxides of silicon, aluminum, calcium, magnesium, iron and some rare metals.

    The percentage of its chemical composition: SiO2 is 52 65;Al2O3 is 16 36;Fe2O3 is; cao is; MGO for; TiO2 is; P2O5 is; k2o na2o to; v2o5.

    The raw ore particle size of coal gangue is larger, and the composition and morphology of pyrite are mainly macroscopic morphologies including nodules, granules, and blocks, and the pyrite in the coal is distributed in the mirror in the form of berry balls and microparticles by microscope and electron microscope, and pyrite is also filled in the cell cavity, and individual is small lenticular and fine-grained disseminated.

    Extended information: Coal gangue is discarded and occupies a large area of land. Sulfide escaping or leaching from coal gangue can pollute the atmosphere, farmland and water bodies.

    Gangue mountains can also spontaneously combust and cause fires, or collapse during the rainy season, silting up rivers and causing disasters. China has accumulated more than 1 billion tons of coal gangue, and will discharge 100 million tons of coal gangue every year.

    Coal gangue instead of fuel: iron; burner burner; burnt lime; **Coal. Production of cement: production of ordinary Portland cement; production of special cement; Production of clinker-free cement.

    Production of building materials: coal gangue sintered bricks, good quality, uniform color; Coal gangue produces light aggregate, which is a kind of porous aggregate selected for the relative density of less concrete.

    The production of coal gangue asbestos is a building material made of coal gangue and lime as raw materials, melted at high temperature and sprayed. Production of chemical products: crystalline aluminum trichloride, with coal gangue and chemical industry by-product hydrochloric acid as the main raw material, through crushing, burning, grinding, acid leaching, precipitation, concentration crystallization and dehydration and other production processes, is a new type of water purification agent.

    5000 kcal 7000 kcal is the coal industry nominal coal quality of a statement, the larger the value of the quality of the better coal, as for the affordability, the actual work is measured in this way, it depends on what you use to do, the value of the larger coal calorie is high, burning resistance and the temperature reaches the height is also high, although 5000 kcal is not as high as 7000, but ** preferential, according to your actual needs, such as you are used to burn boilers, collective hot water or something, do not use 7000, waste, If you are used to make steel, then use good coal, so you combine your own needs to determine, and pay attention to identify the quality of coal in the actual purchase process, good coal is obviously much worse than bad black. Hope it helps

    Hello dear, 2000 kcal coal calorific 1000 tons and a 3500 kcal coal containing 2000 tons of Xunjian with 3000 kcal coal how to match. If the calorific value of coal with a higher number of kcal is a, the calorific value of coal with a lower kcal is b, and the calorific value of the coal to be matched is c, then the weight ratio of the two coals required is a b = (c-b) (a-c) = (3000-2500) (5000-3000) = 500 2000 = 1 4A:

    Weigh 1 part of Changtan 5000 kcal of coal and 4 parts of 2500 kcal of coal and mix them together to get 5 parts of 3000 kcal of coal. The general formula is: a b = (c-b) (a-c).

    4250 tons 4650 kcal tons = 19512500 kcal 2Calculate the target calorie: 6000 tons 4800 kcal tons = 2880000 kcal 3

    Calculate the difference: 2880000-19512500=9287500 kcal 4Divide the difference into extra calories per ton:

    9287500 celery hidden card 4800 kcal tons = tons 5Result: A total of 6,000+ tons of coal were required to lift to 4,800 kcal tons of heat.
