A formula of biocarbon and a biocarbon production process

Abstract

A formula of biocarbon and a biocarbon production process are provided. The formula comprises gangue, yellow waste, potassium nitrate, sodium nitrate, borax, efficient plant particles and water. The production process includes smashing the gangue and the yellow waste into powder having a size of 30 meshes, stirring uniformly, adding the potassium nitrate, the sodium nitrate, the borax and the efficient plant particles, stirring the materials, adding the water, fully mixing, performing cold press molding, and drying to obtain a finished product. The product can be fully combusted, reduces fly ash, and reduces slag heat loss. By detection, 50-60% of the discharging amount of smoke dust is reduced, 50-70% of coal is saved, the heat efficiency is increased by 70-90%, the SO2 content in flue gas is reduced by 40-70%, and the sulfur fixation rate can be more than 50%. Combustion structures and working conditions are changed. The product saves energy, reduces environment pollution, is low in cost and high in benefit, and can be widely used as industrial or household fuel.

Description

Technical field: [0001] The invention relates to a new combustion material, especially the formulation and production process of biochar. Background technique: [0002] Coal gangue is the associated waste rock in coal mine production. It contains a large amount of carbonaceous shale, sandy rock and limestone, and its carbon content is generally 20-30%. Still continue to discharge about 100Mt, covering an area of ​​more than 50,000 mu, seriously polluting the environment, causing damage to the atmosphere, water environment, and farmland, and even coal gangue will spontaneously ignite. Substances are dissolved and enter the canals to pollute water sources, affect human health, and damage the ecological environment. When coal gangue is used as fuel, due to its high sulfur content, low combustion value, and high impurity content, the carbon distribution in coal gangue is uneven, and the fixed carbon content is small, so it is difficult to burn without treatment. In recent year...
