Description
Technical field
The present invention relates to a kind of coal additive, belong to the fuel field, specifically a kind of novel coal-saving comburant.
Background technology
During fuel combustion, produce a large amount of by products, such as CO, SO2, nitrogenous compound etc., be discharged into and pollute environment in the atmosphere, affect human health.Incomplete combustion also produces tar, coke and the ash settling that grades and causes that heat transfer efficiency descends, corroding metal.
The effect of ignition dope is the combustionproperty of improving and improve oil fuel: 1. keep equipment cleaning, reduce structure deteriorate; 2. raising efficiency of combustion, save energy; 3. minimizing topsoil.Existing ignition dope is: silicoorganic compound, can as the ignition dope of gasoline and diesel oil, significantly reduce hydrocarbon polymer, CO and soot emission; Lipid acid and metallic naphthenate can reduce the activation energy of combustion processes, make spontaneous ignition temperature descend sufficient combustion; Oil soluble surfactant can make the abundant divergence of greasy filth increase, the oil nozzle dynamics evenly you, contact fully with air.
Existing industry, domestic fuel additive only stress combustion-supporting effect, and single the time length is short from the consideration of oxygen supply angle, and momentary action is strong, and the combustiblesubstance in the coal can not fully burn, and can not play saving coal, and the discharge of poisonous waste in the flue gas exceeds standard; Some additives have overcome the drawback of traditional coal combustion-promoting agents abrupt release oxygen, and aflame coal can obtain sufficient cracking, burning; Fully release energy, reduce harmful gas emission, but itself still has the loss of thermo-efficiency to the coke-knocking descaling DeGrain of boiler surface.
Summary of the invention
The present invention can not fully be burnt for overcoming the existing single combustiblesubstance of coal additive, and the shortcoming that the discharge of poisonous waste in the flue gas exceeds standard provides a kind of novel coal-saving comburant, by many oxide, catalyzer, sulfur curable agent etc. are formulated, and through coke-knocking descaling, oxygenation is bulk, smoke prevention and dust control, the links such as desulfurization make fire coal be able to abundant burning, improve thermo-efficiency, reduce the discharging of dust and sour gas.
For achieving the above object, a kind of novel coal-saving comburant of the present invention is characterized in that: be made of potassium permanganate 10%, ammonium nitrate 15%, calcium chloride 20%, diatomite 14%, calcium oxide 29%, pure aluminium silicate 12%, it is weight ratio; The preparation method of described ignition dope is: potassium permanganate, ammonium nitrate, calcium chloride, calcium oxide, the pure aluminium silicate with above-mentioned weight ratio is mixed with mixture first, again it is mixed with 15～20% the aqueous solution, then diatomite is impregnated in the solution, then in 70～80 ℃ environment, dries and get final product.
A kind of novel coal-saving comburant of the present invention, its implementation procedure is as follows: press formula rate with raw material blending, during use, its formulation is liquid; Proportioning is as follows: ignition dope, water, coal ratio are 3: 10: 1000, and Direct Uniform behind the ignition dope dilute with water is sprayed at the coal surface, and coal is fully burnt.
A kind of novel coal-saving comburant of the present invention, its principle is: described ignition dope is to be made of potassium permanganate, ammonium nitrate, calcium chloride, diatomite, calcium oxide, pure aluminium silicate, wherein potassium permanganate meet high temperature can releasing oxygen so that oxygen is abundant in the burner hearth; Ammonium nitrate is ignition dope; Calcium chloride, calcium oxide are solid sulfur material, can be with completely objectionable impurities absorption of unburn, and can polluted air; The diatomite adsorption ability is stronger; The above-mentioned raw materials combinations of substances, formed the very strong powder body material of adsorptive power, can directly shed in burner hearth in use, the interior input of papery or plastic sealed container of also can packing into burner hearth, meeting heat can automatically pop and be full of burner hearth and bring into play combustion aid function, a part is attracted on the hearth wall and continues combustion-supportingly, forms the long-acting coal-saving coating, makes whole burner hearth become a large catalyticreactor.
Described ignition dope is under state of combustion, combustiblematerials in the coal is by carrying out catalytic pyrolysis and redox reaction in inboard wall of burner hearth absorption and the skyborne ignition dope that suspends, until fire coal is burnouted fully, and this ignition dope itself can not burnt very soon, so can keep the long period.
A kind of novel coal-saving comburant of the present invention, its beneficial effect is: suppress the effect of soot: fuel combustion not exclusively can produce a large amount of carbon particless and form black smoke; The major cause of its formation has air under-supply or inhomogeneous; Temperature of combustion is low; The activation energy of combustion reactions is high; Can reduce the activation energy of combustion reactions when the adding ignition dope, promote rapid perfect combustion; Suppress the effect of unburn thing: make complete combustion of fuel, do not produce residual hydrocarbon polymer and CO; The result of use of ignition dope: the settling that burning is generated reduces sticking of control slag, prevents that simultaneously fireplace from cracking; Because ignition dope makes complete combustion of fuel, has reduced soot emission; Improve the performance of burning, oil fuel consumption is reduced; Reduced hydrocarbon polymer and CO discharging, the environment of protection meets the flue dust handful of class area and puts environmental protection standard.
