Technical field

The present invention relates to a kind of ignition dope, be specifically related to a kind of ignition dope of boiler, and its preparation method and application.

Background technology

Along with the problem of whole society's environmental pollution and energy consumption is more and more paid attention to, country and the restriction of every profession and trade to the sulphur emissions of coal firing boiler more and more stricter, enterprise is also constantly seeking the approach reducing coal equal energy source and consume simultaneously, to reduce production cost further.The solution being developed as these problems of ignition dope provides feasible approach.But existing ignition dope discharges two aspects for raising efficiency of combustion and decreasing pollution and can not take into account, combustion-supporting effect can not be satisfied the demand, therefore be necessary to develop a kind of new coal firing boiler ignition dope, to improve efficiency of combustion further and to play good solid sulphur depositing dust effect simultaneously.

Summary of the invention

The object of the invention is to: a kind of Combustion improver for boiler is provided, can decreasing pollution, improve efficiency of combustion, prolonged boiler work-ing life.

Another object of the present invention is to: the preparation method that described ignition dope is provided.

Above-mentioned purpose of the present invention is achieved through the following technical solutions:

A kind of Combustion improver for boiler is provided, is prepared from by the raw material of following weight part:

Manganse Dioxide 4 parts, molybdenum oxide 4 parts, ferric oxide 4 parts, 4 parts, zinc oxide, cupric oxide 4 parts, 4 parts, calcium oxide, 4 parts, magnesium oxide, potassium oxide 4 parts, sodium oxide 4 parts, 4 parts, aluminum oxide, tin anhydride 16 parts, strontium oxide 16 parts, one oxidation difluoro 16 parts, 16 parts, No. 97 gasoline,-No. 20 diesel oil 16 parts, ethanol 16 parts, kerosene 16 parts, 10 parts, paraffin, octane 10 parts, nonane 10 parts, decane 10 parts, undecane 10 parts, dodecane 10 parts, eicosane 10 parts, triacontane 10 parts, tetracontane 10 parts.

The present invention also provides the preparation method of described ignition dope, comprises the following steps:

1) by weight, at 20 DEG C, in 10000 parts of water, limit heating edge slowly adds Manganse Dioxide 4 parts, molybdenum oxide 4 parts, ferric oxide 4 parts, 4 parts, zinc oxide, cupric oxide 4 parts, 4 parts, calcium oxide, 4 parts, magnesium oxide, potassium oxide 4 parts, sodium oxide 4 parts, 4 parts, aluminum oxide successively, 65 DEG C are maintained the temperature at after adding, stir 24 hours, obtain mixture I, be down to 30 DEG C for subsequent use;

2) by weight, at 40 DEG C, limit heating edge slowly adds tin anhydride 16 parts, strontium oxide 16 parts, oxidation difluoro 16 parts, No. 97 gasoline 16 parts ,-No. 20 diesel oil 16 parts, ethanol 16 parts, a kerosene 16 parts successively in 10000 parts of water, 80 DEG C are maintained the temperature at after adding, stir 8 hours, obtain mixtures II, be down to 30 DEG C for subsequent use;

3) by weight, at 30 DEG C in 980000 parts of water disposable mixture I, the step 2 adding step 1) and obtain) mixtures II that obtains, and 10 parts, paraffin, octane 10 parts, nonane 10 parts, decane 10 parts, undecane 10 parts, dodecane 10 parts, eicosane 10 parts, triacontane 10 parts and tetracontane 10 parts, 60 DEG C are maintained the temperature at after adding, stir 8 hours, obtain ignition dope of the present invention.

The present invention also provides the described application of ignition dope in coal firing boiler, oil-firing boiler or gas fired-boiler.

In ignition dope of the present invention, metal oxide can play oxygenation effect as oxygenate, thus increases speed of response; Some metal oxides and sodium carbonate solution react the salts substances generated improves fuel reactive behavior as catalyzer, fuel combustion are obtained more abundant, more completely; Some metal oxide can also play the effect of sulphur-fixing agent and dustfall agent, such as ferric oxide, calcium oxide etc., effectively can reduce the discharge of coal smoke and sulfurous gas, thus reduces atmospheric pollution.In a word, ignition dope of the present invention obtains comparatively comprehensively effect after preparing in specific proportions with plurality of raw materials, not only have excellent combustion-supporting property, can significantly improve the efficiency of combustion of fuel during use, has also possessed beneficial effects such as falling pollution, reduction of discharging is put simultaneously.

In the middle of actual use, in combustion-supporting property, after ignition dope of the present invention enters boiler combustion layer, flame can raise to some extent, lighter, adds intensity of combustion and density.Along with the increase of time, furnace temperature raises, and quantity of steam, boiler output all will increase; Burning coal layer expands and raises, and slag is loose, and remaining carbon reduces, and boiler wall dirt progressively comes off, and thermo-efficiency improves.Pressing down in sulphur and depositing dust; find after using ignition dope of the present invention; total sulphur content in Boiler Cinder Surveying has turned over one times; reduce further the desulphurization cost of enterprise, smoke dust discharge concentration and blackness are cut down, and lime-ash carbon content rate reduces; hence improve atmospheric environment; flame is stablized simultaneously, and body of heater is protected, and extends boiler life.
