Abstract
Through the levigated mineral fuel, wherein add at least a energy in conjunction with the alkaline additive that falls objectionable impurities, and it is burnt down less than 1300 ℃ at the burning bed temperature.If the alkaline additive of levigated solid fuel and adding kept in airtight basically reaction chamber 10 to 180 minutes, solid-fuelled moisture content＞15% in reaction chamber, temperature is kept above 40 ℃, but be lower than 100 ℃, and burning is burnt under bed temperature≤830 ℃, thereby can realize low harmfulization burning.
Description
The present invention relates to giving processing and hanging down harmfulization incendiary method of mineral solids fuel.This solid fuel is through wearing into less than 3mm particulate process, wherein add at least a can with objectionable impurities bonded alkaline additive, and make it be lower than 1300 ℃ of burnings down at the burning bed temperature.
Mineral fuel generally will be pulverized before burning and be dry, are not suitable for the powder burning if the solid fuel fineness of grinding conforms to, and that is not compressed into brick shape or granular at the also available high pressure of pulverizing and dry back with solid fuel.Solid-fuelled compression brings significant advantage for conveying and storage.
Contained impurity is as the release of sulphur, chlorine, fluorine and heavy metal not by compression influence basically in the fuel.So the distribution that can bring significant nuisance during burning, such as, SO
2, HCl and HF.
From as can be known, in conjunction with falling the deleterious acidic material, need in the solid fuel that contains waste material (Abfallstoffe), to add alkaline additive for effectively such as DE3440593AI.Know that in addition the burning bed temperature should be too not high, in order to avoid in back to back combustion processes, destroy in conjunction with the objectionable impurities of falling.Can also know that therefrom the burning bed temperature should transfer to and is lower than 1300 ℃, is preferably between 800-1000 ℃.
From DE3717191C1 as can be known, do low harmfulization burning, should be tuned to a kind of alkaline additive of adding in the rubbish of 15-35 weight percentage of regulation in humidity for making rubbish (M ü ll).Rubbish stopped 10 minutes at least at reaction chamber, burnt being lower than under 850 ℃ the temperature then.This method can not be used to burn solid fuel of levigated solid fuel, particularly compression-type.
Task of the present invention is a kind of above mentioned those class methods of explanation, makes levigated mineral solids fuel also can realize low harmfulization burning.
Task of the present invention solves by above mentioned that class technological method, in this method, the alkaline additive of levigated solid fuel and adding kept in airtight basically reaction chamber 10 to 180 minutes, wherein the solid fuel water capacity is greater than 15%, reaction chamber temperature is kept above 40 ℃, be lower than 100 ℃, be equal to or less than under 830 ℃ at the burning bed temperature and finish burning.
The present invention adopts be a sort of on all four treating processes of being advised during with incineration firing carry out mineral solids fuel suit give processing (distinguishing to some extent) with process technology so far, for mixing mutually with alkaline additive, mineral solids fuel is adjusted under the high relatively humidity, and adjusts to comparatively high temps in an airtight reaction chamber.Reaction chamber preferably indirect heating and preferably be heated to about 60 ℃.
Then brick shape or granular is made in the solid fuel compression.By mentioned give treatment measures make objectionable impurities particularly acidic cpd be combined into salt with high decomposition temperature, bonded salt is stayed in the combustionresidue and is not decomposed into objectionable impurities during like this in burning bed temperature≤830 ℃.
Head of the present invention attacks the solid fuel that this compression is provided, and it only produces seldom objectionable impurities when burning, such as its SO
2Content is less than 2%.
Be to implement this method, the moisture content of mixture in the reaction vessel is transferred to＞20%, the alkaline-earth metal mixture is suitable to alkaline additive, preferably CaCO
3And/or MgCO
3, calculate by stoichiometry, add in the solid fuel with amount greater than 1.0.
By this kind to the solid-fuelled unusual processing of giving, wherein, for adding alkaline additive, solid fuel is adjusted to the moisture content that gives elder generation's regulation, make solid fuel in reaction vessel, stay for some time (more preferably greater than 20 minutes) again, then solid fuel is carried out drying, just can be so that high bituminous coal and the brown coal of sulfur-bearing also can reach low harmfulization burning.
Claims (6)
1, mineral solids fuel give working method and low harmfulization combustion method thereof, it comprises makes solid fuel wear into the levigate process of particle less than 3mm, wherein add a kind of alkaline additive that is used to be combined with harmful substances at least, and at the burning bed temperature less than 1300 ℃ of down burnings, this method is characterised in that, the alkaline additive of levigated solid fuel and adding keeps 10 to 180 fens clock times in airtight basically reaction chamber, solid-fuelled moisture content＞15% in reaction chamber, temperature keeps above 40 ℃, be lower than 100 ℃, and under burning bed temperature≤830 ℃, finish burning.
2, by the method for claim 1, the residence time that it is characterized in that solid fuel and alkaline additive mixture is between 20 to 120 minutes.
