Abstract
A combustion adjuvant for coal is prepared from potassium permangnate, sodium chloride, Fe2O3 and chlorinated rare-earth through mixing and dissolving in water to obtain suspension. After mixed with coal, it can make combustion stronger, increase temp and thermal efficiency, reduce carbon content in cinder and the blackness of smoke, so saving coal and reducing environmental pollution.
Description
What the present invention relates to is a kind of high-efficiency coal combustion adjuvant that improves coal burning thermo-efficiency, reduces coal burning generation pollution.
In the coal burning process, it is insufficient often to burn, and the waste coal resources cause environmental pollution.The present additive for coal combustion that uses, as " energy saving and pollution reducing coal additive " (number of patent application 92115150.0), the product cost height, and easily cause the ignition dope spontaneous combustion, and use inconvenience, be difficult to promote.Another kind of " production method of catalytic desulfurizing agent for coal " (number of patent application 96109822), its product reduce pollution effects and still can as coal combustion adjuvant, but thermo-efficiency improves little, production method is too complicated, also can cause combustion equipment oxidation corrosion, and combustionvelocity waits shortcoming slowly.
The objective of the invention is to make that a kind of preparation is simple, easy to use, product cost is low, produce and use in non-environmental-pollution, saving coal easy to utilize reduces the coal combustion adjuvant of pollution.
The technical solution adopted in the present invention is a mixture of selecting for use potassium permanganate, sodium-chlor, ferric oxide and rare earth chloride to form.Potassium permanganate is strong oxidizer, the oxidizing reaction that takes place when participating in coal burning; The Manganse Dioxide that the reaction back generates is the catalyzer of oxidizing reaction, has quickened the carrying out of oxidizing reaction; The oxygen that generates during reaction makes coal burning more abundant." microexplosion " at high temperature takes place in sodium-chlor, makes coal-fired bulk porous, increases combustion surfacearea, helps coal fully to burn.Ferric oxide has antirust corrosion inhibition, at high temperature protects burner hearth and flue.Rare earth chloride is ignition dope and sweetening agent; Rare earth chloride is displaced when the rare earth element that comes burns and emits big calorimetric under the high temperature, plays combustion-supporting effect; Can also react with the sulphur in the coal, play solid sulphur desulfidation, help to eliminate the stink that coal burning produces.
Embodiments of the invention:
Embodiment 1: coal combustion adjuvant prescription (weight percent):
Potassium permanganate 5
Sodium-chlor 65
Ferric oxide 29.9
Rare earth chloride 0.1
Embodiment 2: coal combustion adjuvant prescription (weight percent):
Potassium permanganate 50
Sodium-chlor 40
Ferric oxide 9
Rare earth chloride 1
When the mixture of the above-mentioned prescription of the present invention was water-soluble, wherein potassium permanganate, sodium-chlor and rare earth chloride were dissolved in water fully, and ferric oxide is suspended state.Behind this suspension and coal uniform mixing, deliver to the stove internal combustion, can play overheavy firing, improve furnace temperature, reduce boiler slag carbon content, reduce oke exhaust blackness, improve the effect of boiler thermal output, save effect coal-fired and the protection environment thereby reach.
Claims (1)
1. the manufacture method of a coal combustion adjuvant is characterized in that being grouped into (weight percent) by following one-tenth:
(1) potassium permanganate 0.5～99.5
(2) sodium-chlor 0.1～90
(3) ferric oxide 0.1～30
(4) rare earth chloride 0～1
Its method of manufacture and use thereof is: after mentioned component is mixed, add the water of 4～10 times of its weight, make suspension; With itself and coal uniform mixing, send into the stove internal combustion, have the effect that improves thermo-efficiency, reduces boiler slag carbon content and oke exhaust blackness.
