Environment friendly energy-saving super strength combustion supporting efficient synthetic coal

Abstract

The invention discloses environment-friendly energy-saving extra-strong combustion-supporting high-efficiency synthetic coal, which is characterized by comprising the following steps: adopting plant charcoal power and natural coal powder of powerful renewable resources to prepare into a main material through a scientific formula according to the variety and the quality of coal; adding a mixed material of coal gangue powder and fly ash powder of industrial waste to synthesize a filling auxiliary material, and reconstructing and changing structures, the performance and the characteristics of the coal to make the coal reach the highest efficiency; then adding a strong-oxygen combustion-supporting high-efficiency coal-saving synergistic fire-slowing agent which has quick firing, can prolong the combustion time of the coal, can make low-grade coal completely combusted, improve thermal efficiency, save the coal, has no pollution, and can achieve the aims of eliminating smoke, dedusting, supporting combustion and desulfurizing; and finally adding a certain amount of water , evenly stirring , and performing coal molding and manufacturing by special coal-making machinery . The coal is high-efficiency coal, has the use efficiency three to six times of that of the prior ordinary coal, is a novel energy-saving high-efficiency energy source, has the coal-saving rate reaching 80 percent or so, has extremely high coal-saving rate and convenient use, is safe, reliable and easy to store, and is called 'overground coal mine' and 'green coal'.

Description

technical field [0001] The present invention relates to an environment-friendly and energy-saving super-combustion-supporting high-efficiency synthetic coal. More specifically, it is a kind of coal that is especially suitable for civil and industrial use, and is suitable for coal mines, coke plants, coal dressing (washing) plants, briquette plants and various coal mines. Coal energy enterprises produce various environmentally-friendly, energy-saving and high-efficiency briquettes using environmentally-friendly and energy-saving super-combustion-supporting and high-efficiency synthetic coal technology. New energy, the coal saving rate can reach about 80%, and the environmental protection performance is very good, it is the coal with the highest coal saving rate and the best environmental performance in the world. The invention also relates to a production method of environment-friendly and energy-saving super-combustion-supporting high-efficiency synthetic coal. Background te...

Problems solved by technology

[0003] At present, it is known that the existing raw coal, coke, molded coal, and coal combustion accelerants have not fundamentally solved and changed the quality of coal, and the use efficiency, combustion performance, and coal saving rate of the coal are very low, resulting in serious waste of coal. All there is following shortcoming and weak point:

[0005] 2. Coke: Although the utilization rate is good, it has no coal-saving performance, and its combustion value is not greatly improved. Most of it is produced by machine coke. Due to the high production cost of machine coke, the secondary pollution is more serious, and the production The investment is large, and the production has certain pollution, so most coking (coke) plants have been ordered to close by the government

[0006] 3. Formed coal: refers to various types of coal, such as honeycomb coal, etc. Since yellow mud or sodium silicate is used as a binder, when burning, the yellow mud itself consumes part of the heat energy, wasting energy, and its thermal efficiency is low. Sodium is easy to absorb moisture and decompose, affecting the strength of coal, and it is inconvenient to store and transport; the utilization rate of briquette coal is extremely low, and its economic added value is also low. Over 20%, for a long time, due to the backward technology of domestic coal use, the thermal efficiency is only about 20%, wasting a lot of energy, and the pollution level cannot be reduced, resulting in serious scattered pollution
