The coal gangueis developed into the high-grade fuel. so a novel energy treasure house is developed for human civilization, and the extraction and the consumption of fossil fuel such as coal, petroleum, natural gasand the like are reduced; the fuel expands a new time space for human understanding and exploration and is expected to change human notion and thought and make people understand the material world from a new time space field; and the fuel can possibly eliminate the threat of energy crisis to human civilization and prolong human civilization for several thousand years or hundreds of thousands of years.

Description

Internal energy fuel of coal gangue
Technical field:
Internal energy fuel of coal gangue.
Background technology:
The a large amount of energy of human civilization consumption cause energy dilemma and ecocrisis, threaten human civilization existence.Coal gangue is the industrial residue that coal mining and coal washing generate, and is to hang down the grey black look rock harder than coal with the carbon content of coal seam association in the coal-forming process, digging gangue, top board base plate interlayer spoil is arranged and wash spoil.The chemical constitution complexity mainly is made up of kaolin, quartz, montmorillonite, feldspar, illite, Wingdale, iron sulphide, aluminium sulfide etc., contains tens kinds of chemical elements.Contain silicon-dioxide (SiO 2) 51% to 65%, aluminum oxide (Al 2O 3) 16% to 36%, ferric oxide (Fe 2O 3) 2.28% to 14.63%, calcium oxide (CaO) 0.42% to 2.32%, magnesium oxide (MgO) 0.44% to 2.41%, titanium oxide (TiO 2) 0.90% to 4%, Vanadium Pentoxide in FLAKES (P 2O 5) 0.078% to 0.24%, potassium oxide (K 2O) 1.45% to 3.9%, sodium oxide (Na 2O) 1.45% to 3.9%, Vanadium Pentoxide in FLAKES (V 2O 5) 0.008% to 0.01%, total sulfur 5% to 15%, also have many moving trace elements.Thermal value 4.19 is to 12.6MJ/kg, loss on ignition 5% to 15%.Pile up like a mountain takies a large amount of land resourcess through mine coal spoil for many years in the colliery, the weathering spontaneous combustion of exposing to the sun and rain, and dust waste gas rainwater soaks molten, contaminated land ambient atmosphere environment and water surrounding.Existing treating method major part is cost with the pollutant atmosphere, particularly interests are ordered about coal gangue pulverized to mix to sell in raw coal and are boiler oil, causing the discharging major polluting atmosphere environment that exceeds standard, almost is to discharge stacking again with the amount solid slag, only is to shift the coal gangue stockyard.
Summary of the invention:
The internal energy fuel of coal gangue goal of the invention is: propose the theoretical and new environmental protection technology of new environment protection, new energy development theory and developmental technology of new energy resources; Propose internal energy fuel of coal gangue, develop the agent of coal gangue activated with energy, energy in the realization coal gangue burns under the coal combustion conditions and discharges is developed internal energy fuel of coal gangue.Physical chemistry knowledge: carbon (C) hydrogen (H) oxygen (O) produces the element of heat when being the coal gangue burning, and less because of the flammable hydrocarbon oxygen element content of free state in the coal gangue, so coal gangue combustion heating amount is lower, toxic and harmful is discharged contaminate environment.Element exists individual character and general character, and there is fusion in light element hydrogen (H), and four hydrogen atoms of two hydrogen molecules nucleosynthesis take place under high-temperature and high-pressure conditions generate two helium (He) atom, discharge big energy.There is fission in heavy element uranium (U), and the uranium alpha-decay becomes thorium (Th) and helium (He), and thorium β decays into protactinium (Pa), and uranium is fissioned into xenon (Xe) and strontium (Sr) and discharged big energy under high-temperature and high-pressure conditions.And perhaps under certain condition, can exist certain variation to release energy between the neutral element, the people does not know only as yet.Coal gangue chemical constitution complexity contains tens kinds of chemical elements, has the condition of tapping a new source of energy.Therefore develop the agent of coal gangue activated with energy.Coal gangue activated with energy agent development purpose is: promote releases of burn in the coal gangue under the coal combustion conditions, perhaps impel the molecule of the contained material of coal gangue or atomic structure to break up to shuffle to reconfigure and release energy, protect environment Gu sulphur is consolidated carbon.Utilize the internal energy fuel of coal gangue temperature of combustion to be higher than the coal temperature of combustion, industrial residue internal energy fuel such as exploitation made form red mud, ardealite under combustion temperatures condition more.
