Abstract

The present invention relates to a coal-saving additive which comprises the following ingredients: 85 to 94% of sodium chloride, 1.6 to 5% of potassium permanganate, 3 to 8% of sodium chlorate, 0.8 to 2.5% of ferric oxide and 0.15 to 0.2% of cellulose nitrate, wherein the sodium chlorate can be replaced by potassium chlorate. The coal-saving additive of the present invention is doped in coal proportionally to make the coal sufficiently combusted. Practices show that the hearth temperature can be effectively enhanced by more than 80 DEG C, the heat efficiency is enhanced by more than 10%, the coal saving rate is enhanced by more than 15%, the fume exhaust blackness is reduced by 1 to 2 grades, and the slag discharge amount is reduced by about 15%.

Description

A kind of coal-saving additive

The present invention relates to a kind of being entrained in and to make the combustion-supporting coal-saving additive of coal in the fire coal.

At present, energy shortage has been a worldwide problem, and its outlet has two nothing but: seek the energy that upgrades or improve existing rate of energy.Coal a kind of the most common also be one of most important energy, it is widely used in industrial and mining enterprises and the daily life, makes full use of existing coal resource and will play very big effect to Economic development from now on.Traditional coal-saving method mainly is repeatedly to reuse, as being made fuel again, still imperfect combustion cinder miscellany is used for fluidizing furnace etc., how many this class measures has played effect, but the combustionproperty of fuel itself there is no remarkable improvement, still contains the combustiblematerials of high level in the cinder; Owing to burning insufficient thereby also can causing useless cigarette and waste gas, environment is polluted on the other hand.

Purpose of the present invention is with regard to being at the present situation of above-mentioned prior art and provide a kind of being entrained in can make the combustion-supporting high-efficient coal saving additive of coal in the fire coal.

The object of the present invention is achieved like this: contain following composition in the coal-saving additive by weight percentage, sodium-chlor 85-94%, potassium permanganate 1.6-5%, sodium chlorate 3-8%, ferric oxide 0.8-2.5%, nitrocellulose 0.15-0.2%.

Mix product of the present invention in the fire coal by a certain percentage, can make coal-fired fully burning, practice shows can effectively improve fire box temperature more than 80 ℃, improve boiler thermal output 10% or more, coal saving rate is more than 15%, and makes oke exhaust blackness reduce by 1～2 grade, slag emission amount reduction about 15%.

Embodiment below in conjunction with three different ingredients of the present invention is described in further detail the present invention.

Embodiment one:

By weight percentage, get potassium permanganate 4.5%, sodium chlorate 7.8%, ferric oxide 2.5%, nitrocellulose 0.2%, mix in 85% the sodium-chlor, then need pulverize as caking in the raw material, slowly stir then less than 0.04% until uniformity coefficient, temperature of charge is to be lower than 55 ℃ for good when stirring, and last finished product should not have other impurity and the surface is reddish-brown, is particulate state and powdered blended solid;

Present embodiment is applicable to the low grade coal that calorific value is lower.

Embodiment two:

By weight percentage, get potassium permanganate 1.85%, sodium chlorate 3%, ferric oxide 1%, nitrocellulose 0.15%, mix in 94% the sodium-chlor, then need pulverize as caking in the raw material, slowly stir then less than 0.04% until uniformity coefficient, temperature of charge is to be lower than 55 ℃ for good when stirring, and last finished product should not have other impurity and the surface is reddish-brown, is particulate state and powdered blended solid;

Present embodiment is applicable to the fat coal that calorific value is higher.

Embodiment three:

By weight percentage, get potassium permanganate 2%, sodium chlorate 3.5%, ferric oxide 1.2%, nitrocellulose 0.2%, mix in 93.1% the sodium-chlor, then need pulverize as caking in the raw material, slowly stir then less than 0.04% until uniformity coefficient, temperature of charge is to be lower than 55 ℃ for good when stirring, and last finished product should not have other impurity and the surface is reddish-brown, is particulate state and powdered blended solid;

Present embodiment is applicable to the common coal that most of calorific values are moderate.

The also available Potcrate of sodium chlorate in above-mentioned substitutes, and its content is constant.

The present invention in use, with coal: additive: water=1000: 2.5: 15～60

(the dried temperature degree on coal is decided)

That is: 1 ton of coal admixture is dissolved in 2.5 kilograms additive in the 15-60 kg of water.

Example: 1 ton of additive is put in the pond and is added 6 tons of water, makes its dissolving, by device its even admixture is gone into (as using the spray form) in 400 tons of coals, just can reach energy-efficient purpose.
