Abstract
The invention relates to a decoking coal-saving combustion improver. The decoking coal-saving combustion improver is characterized by comprising chromic anhydride, copper chloride, manganese dioxide, vermiculite, fluorite, alumina, active magnesium oxide, active calcium oxide and nickel oxide. The decoking coal-saving combustion improver has the advantages that a decoking agent is not required to be sprayed into a boiler, so that the trouble of decoking is reduced, the heat efficiency of the boiler can be improved by about 1%-3%, and the good economic effect is achieved.
Description
Technical field
The present invention relates to a kind of decoking coal-saving comburant.
Background technology
All the time, all contain a large amount of sulphur and other dirts in the fuel of China, after burning, can form a large amount of toxic substances, after this class material is run into heat exchanger, can form a large amount of vitriol and sulphite on the surface of boiler, these materials have extremely strong corrodibility, finally can form a large amount of slags on the surface of boiler, thereby influence the work-ing life of boiler, reduce hot rate of utilization, after a large amount of depositions of the slag that forms, can cause comes off automatically causes fire extinguishing, blowing out, even cause danger.
Summary of the invention
The present invention is exactly at the problems referred to above, provide a kind of decoking coal-saving comburant: it is characterized in that being formed by chromic trioxide, cupric chloride, Manganse Dioxide, vermiculite, fluorite, aluminum oxide, activated magnesia, active calcium oxide and nickel oxide, the quality proportioning of above-mentioned substance is: chromic trioxide 15-30, cupric chloride 5-15, Manganse Dioxide 10-20, vermiculite 10-20, fluorite 5-10, aluminum oxide 5-15, activated magnesia 5-15, active calcium oxide 5-10, nickel oxide 5-15.
2. a kind of decoking coal-saving comburant as claimed in claim 1, the quality proportioning that it is characterized in that described material is: chromic trioxide 20, cupric chloride 10, Manganse Dioxide 15, vermiculite 15, fluorite 5, aluminum oxide 10, activated magnesia 10, active calcium oxide 5, nickel oxide 10.3. one kind prepares decoking coal-saving comburant preparation method as claimed in claim 1, its
Be characterised in that and may further comprise the steps:
Step 1: batching is added to various raw materials in the cylinder agitator by loader according to proportioning described in the claim 1;
Step 2: stir, start agitator, fully mixed 15 minutes, with the material after stirring be put in the automatic filling machine;
Step 3: check, packing, warehouse-in.
1, slag-removing ash-cleaning mechanism: this product is suited the remedy to the case from slag-bonding mechanism, to improve coal ash fusion temperature, coal ash viscosity is purpose, contain and satisfy the chromium material that promotes that the slag type is changed to crystal form slag type by vitreous state, the aluminosilicate of chromium ion in ash component is combined, constantly iron ion formed high temperature mineral group network with endoplasm with resembling adding (the high ferrous components in the ash content).Its molten solubility temperature is between 1380～1440 ℃, and when resultant is high temperature material when flying to the burner hearth tube wall, they have located to solidify or half curdled appearance, so can not generate the slag body of heterogeneous body.Solved the little problem of home and abroad prior art products suitability, comprehensive action by each composition, the effect that various coal-fired ash fusion points, ash viscosity, slagging scorification type, sedimentation all are significantly increased can be reached, the long-acting cycle of coal dust boiler with dry bottom furnace safety and economic operation can be guaranteed.(improving 80～220 ℃ of ash fusion points, 10～30 times of viscosity).
2, Energy saving mechanism: in the specific burning situation, the continuous interpolation of chromium material is because the effect of pyrochemistry fission catalysis in stove, the Sauerstoffatom that generates has huge heat energy, can make the burner hearth core temperature improve 80～140 ℃, obviously improve coal vapour ratio, coal saving rate is (can reach 5-12%) significantly.Started and used the energy-saving and cost-reducing frontier of pyrochemistry fission catalyst mechanism principle.
3, there is not the corrosion side effect: adopt the use of industrial table salt and water-soluble potassium, sodium salt in the existing deslagging agent of eliminating, prevent that it is to the high and low temperature flue gas corrosion of boiler.To the high temperature corrosion effect of boiler chromium-base slag-removing ash-cleaning joint agent at 12CrlMoV stainless steel and 20# steel boiler, the result shows the nearly blank value of demonstration, and boiler is not had corrosive nature through Xi'an thermal technology institute.
4, this product chromium base be similar to the most effective product in the American-European deslagging agent, and its anti-scorch performance that removes the gred is far above external like product performance except the agent of (preventing) slag.The serious coking of furnace combustion zone has not only been removed in this agent, and has significantly alleviated the dust stratification of height superheater, and can reduce fly ash combustible material, and funnel temperature is tending towards normal range, can improve about boiler thermal output 1-3% serious coking dust stratification boiler
