Novel inorganic fuel

Abstract

The invention discloses a novel inorganic fuel which is characterized by being prepared from the following raw materials consisting of two or more than two inorganic solid substances in percentage byweight: 5-50% of calcium ions, 2.5-20% of one or two of aluminum ions and iron ions, 2-30% of silicon ions and 0.5-10% of an additive, wherein all substances are crushed till the particle diameter issmaller than 180 meshes and are uniformly mixed; an ignition substance is a nontoxic and harmless substance which is capable of generating a high temperature of 1500 DEG C or greater when being combusted and is easy to ignite; and the additive is one or more of sodium carbonate, mirabilite, manganese dioxide and potassium permanganate. By adopting the novel inorganic fuel, not only is the solid waste pollution problem of mining companies, building wastes and a part of chemical companies solved, but also waste utilization is achieved, the wastes can be turned into wealth, coal can be partiallyor completely replaced, the emission amounts of sulfur and nitrogen can be reduced in combustion, residues and gases generated after combustion are free of toxic and / or harmful substances, the residues can be recycled, the environment can be improved, and the energy can be saved.

Description

technical field

[0001] The invention relates to the field of novel fuels, in particular to a novel inorganic fuel. Background technique

[0002] Due to the pollution of the atmosphere caused by coal combustion, the country restricts or cancels coal as civil or industrial coal in some areas, and uses natural gas or electricity instead of coal, which causes the cost of fuel to rise. Therefore, research and development of low-cost, low-pollution coal alternative fuels is an invention that benefits the country and the people.

[0003] Solid waste, construction waste, and soil from various industrial and mining enterprises, these inorganic solid substances contain calcium ions, aluminum ions, silicon ions, iron ions, and a small amount of sodium ions, magnesium ions, etc. These inorganic substances are basically composed of oxides of the above-mentioned ions. These ions basically exist in the form of oxides in nature, such as calcium carbonate (CaCO3), calcium oxide (CaO), calc...
