Abstract
The invention relates to an improvement of a novel combustion improver, and especially relates to the novel combustion improver by combining combustion supporting and sulfur fixation. The combustion improver is prepared by mixing the following components by mass ratio: 25-30% of dolomite dust, 5-15% of dicyclopentadieny iron, 3-10% of chromium trioxide, 5-8% of silica, 3-10% of bauxitic clay, 3-15% of sodium carbonate, 3-18% of zinc oxide and 15-30% of activated clay through complex formulation. According to the invention, coal acceleration combustion is realized, heat efficiency is increased, the effect is good, the amount is less, the novel combustion improver has obvious coal saving and environmental protection effects, the inferior coal which is difficult to perform normal combustion can perform the effect. The corrosion of a boiler is not generated by long-term usage, the calcium sulfate fouling in the boiler is reduced, and the operation security and usage life of the boiler can be increased.
Description
Technical field
The present invention is the improvement to novel ignition dope, relates in particular to a kind of novel ignition dope that integrates combustion-supporting, solid sulphur.
Background technology
For improving coal combustion efficiency and/or reducing pollutant emission, and coking etc., a kind of method is in fire coal, to add to have corresponding function coal combustion improver, for example ignition dope, sulphur-fixing agent, decoking agent, smoke suppressor.Although prior art has various function additive for fire coal, but due to the single function singleness that causes of formula composition, so can only separately use, and the addition of coal combustion improver own is minimum, equally interpolation is not only pretty troublesome, and interpolation work is loaded down with trivial details, cause people to be reluctant to use, and few because of addition, be difficult to mix, affect practical effect.Secondly, the more employing strong alkaline substance of existing additive is tight to equipment corrosion.
Summary of the invention
The object of the invention is mostly to adopt and help oxygen combustion principle for prior art,, boiler surface is had to certain corrodibility, can reduce boiler work-ing life.Secondly, function singleness, lacks smoke elimination, anti-coking, solid sulfur functional, and sulphur emissions exceeds standard.
Concrete technical scheme of the present invention is: a kind of novel ignition dope, is characterized in that: the mass ratio of each integral part is ground dolomite 25-30%; Dicyclopentadieny iron 5-15%; Chromium trioxide 3-10%; Silicon-dioxide 5-8%; Bauxitic clay 3-10%; Sodium carbonate 3-15%; Zinc oxide 3-18%; The composite mixing composition of atlapulgite 15-30%.
The invention has the beneficial effects as follows: provide a kind of and can significantly improve coal-fired combustionproperty, accelerate combustion, improves thermo-efficiency, and effective consumption is few, have significantly economize on coal, environment protecting, can make the burning environment of inferior quality coal that is difficult to trouble-free burning originally play a role.Life-time service, boiler does not only produce corrosion, can also reduce the fouling of calcium sulfate in boiler, improves boiler operatiopn security and work-ing life.
Embodiment
Example 1
A kind of novel ignition dope, mass ratio is ground dolomite 30%; Dicyclopentadieny iron 10%; Chromium trioxide 5%; Silicon-dioxide 5%; Bauxitic clay 5%; Sodium carbonate 10%; Zinc oxide 10%; The composite mixing composition of atlapulgite 25%, the present invention in actual use, by flue gas and slag are detected, the Reducing exhaust emission of pollution substance, and burning of coal rate increases, boiler does not only produce corrosion, can also reduce the fouling of calcium sulfate in boiler, improves boiler operatiopn security and work-ing life.
