Abstract
The invention discloses a coal-saving combustion improver, which comprises the following compositions by mass percent: 26-32% of activated carbon, 18-28% of sodium chloride, 16-20% of potassium permanganate, 11-15% of ferric chloride, 5-8% of aluminium oxide, 4-6% of copper oxide, and 0.5-1% vanadium pentoxide. According to the invention, the coal-saving combustion improver can be added into raw coals, so as to shorten ignition time of coal by 14-18% and improve the heat efficiency of coal by 2-5%.
Description
Technical field
The present invention relates to coal-fired field, particularly relate to a kind of coal-saving comburant.
Background technology
The SO of China

Summary of the invention
The object of this invention is to provide a kind of coal-saving comburant, coal-saving comburant of the present invention joins 14-18% ignition time that can shorten coal after in fire coal, and thermo-efficiency can improve 2-5%.
In order to achieve the above object, the technical solution used in the present invention: a kind of coal-saving comburant, comprises the component of following mass percent:
Gac 26-32%
Sodium-chlor 18-28%
Potassium permanganate 16-20%
Iron(ic) chloride 11-15%
Aluminum oxide 5-8%
Cupric oxide 4-6%
Vanadium Pentoxide in FLAKES 0.5-1%.
During use, in raw coal, add the above-mentioned ignition dope of 2-4 ‰.After adding ignition dope of the present invention, gac induction is combustion-supporting, accelerates ignition rate and the rate of combustion of coal, shortens the ignition time of coal; Raw coal is activated under the catalysis of sodium-chlor, potassium permanganate, iron(ic) chloride, aluminum oxide, cupric oxide, Vanadium Pentoxide in FLAKES, reduce the point of ignition of coal, shorten the ignition time of raw coal, the activation of raw coal simultaneously also improves the thermo-efficiency of coal, the raising of coal thermo-efficiency, the temperature coal consumption making acquisition same is reduced, thus achieves the object of economizing on coal.Through test, the ignition time of coal is shortened 14-18%, and the thermo-efficiency of coal improves 2-5%.
In addition, after adding coal-saving comburant of the present invention, the CO that coal produces in the process of burning and cupric oxide react, and reaction equation is: CuO+CO=CU+CO
2, convert by chemical reaction the carbon monoxide produced in coal combustion process to carbonic acid gas, reduce coal-fired poisoning risk.
Preferably, described coal-saving comburant also comprises Manganse Dioxide, and its mass percent is 0.5-1%.
