Abstract
The invention relates to a powdery coal-saving combustion improver and a preparation method thereof. The powdery coal-saving combustion improver is composed of the following components by weight: 15 parts of titanium dioxide, 3 parts of copper oxide, 5-10 parts of ferric oxide, 13 parts of silicon dioxide, and 15-20 parts of manganese dioxide. According to the powdery coal-saving combustion improver and the preparation method thereof, the production process is simple, also reasonable raw material variety and composition are selected in the formula, the raw materials are mixed evenly and gradually take effect along with the rise of combustion temperature in a coal combustion process, and the combustion-supporting duration is long. Also, macromolecular compounds in coal can fully burn to release a lot of heat, the exhaust gas emission is reduced, the environmental pollution is reduced, and also the effects of sulfur fixation, decoking and smoke abatement can be achieved.
Description
Technical field
The present invention relates to energy-conserving and emission-cutting technology field, particularly relate to a kind of powdery coal-saving comburant and preparation method thereof.
Background technology
The productive life of coal and people is closely bound up.But coal is non-renewable resource, along with the propelling of process of industrialization, also day by day strengthen the demand of coal, therefore economizing on coal is the vital task faced at present.In addition, coal often produces a large amount of soot dust granules and obnoxious flavour in combustion, is unfavorable for environment protection.
In coal, add the important means that ignition dope is energy-saving and emission-reduction, but still there is following problem in ignition dope at present:
1, only from the angle improving oxygen supply, momentary action is strong, but persistence is shorter, and effect of coal saving is undesirable;
2, in coal, combustiblesubstance still can not get Thorough combustion, and thermo-efficiency is not fully utilized, and sulfide in flue gas and harmful gas emission exceed standard.
3, cost is higher, is unfavorable for large-scale production application.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of powdery coal-saving comburant and preparation method thereof, not only production technique is easy, and in formula the kind of choose reasonable raw material and composition, make each raw material Homogeneous phase mixing, have an effect gradually with the rising of temperature of combustion in coal burning process, the combustion-supporting time length is long; The macromolecular compound Thorough combustion release amount of heat in coal can be made simultaneously, decrease the quantity discharged of waste gas, decrease environmental pollution, there is the effect of solid sulphur, decoking, smoke elimination.

The invention has the beneficial effects as follows: the present invention selects cupric oxide, ferric oxide, silicon-dioxide, Manganse Dioxide, titanium dioxide as the raw material of powdery coal-saving comburant; and the proportioning of the best selected; the powdery coal-saving comburant be made into can improve the efficiency of combustion of coal; make coal Thorough combustion; release amount of heat; decrease the quantity discharged of waste gas simultaneously, be conducive to protection of the environment.
A preparation method for powdery coal-saving comburant, comprises the following steps:
1) cupric oxide, ferric oxide, silicon-dioxide, Manganse Dioxide are pulverized respectively, sieved;
2) step 1 is taken respectively) cupric oxide 3 weight part, ferric oxide 5-10 weight part, silica 13 weight part, the Manganse Dioxide 15-20 weight part of powdery that obtain, add titanium dioxide 15 weight part, mix, obtain pulverulent mixture;
3) by step 2) calcining of the pulverulent mixture prepared, cooling after calcining, packaging.
The invention has the beneficial effects as follows: preparation method's process of powdery coal-saving comburant of the present invention simply, easily operates, do not need special production unit, various raw material can be mixed into one uniformly, effects of energy conservation and environmental protection is obvious, has the effect of solid sulphur, decoking, smoke elimination.
On the basis of technique scheme, the present invention can also do following improvement.
Further, step 1) in, the granularity after grinding is 80 orders.
Adopt the beneficial effect of above-mentioned further scheme to be: granularity is less, conveniently to mix with coal, reach the effect of good coal-saving burning.
Further, step 3) in, calcine 10 hours under 300 DEG C of conditions, be cooled to 25 DEG C.
