Abstract
The invention discloses a coal combustion improver. The coal combustion improver is prepared from the following raw materials in parts by weight: 1-2 parts of potassium permanganate, 3-5 parts of ammonium nitrate, 5-8 parts of calcium chloride, 2-8 parts of magnesium nitrate, 1-3 parts of aluminium oxide, 10-20 parts of ammonium hydrogen carbonate and 20-30 parts of activated carbon. When mixed with coal for use, the coal combustion improver can improve the heat efficiency of a boiler, reduce the emission of black smoke, save coal and prolong the service life of the boiler.
Description
Technical field
The present invention relates to a kind of ignition dope, be specifically related to a kind of coal combustion-promoting agents.
Background technology
Coal combustion-promoting agents has and more multiplely to use aborning, is generally all applicable to conventional coal.But, because the quality gap of coal is larger, so the combustion-supporting effect of these existing coal combustion-promoting agents is unbalanced, use middle discovery, to the less effective of hard coal and brown coal, have the features such as high, the high point of ignition of density, low volatile and low hydrogen content due to hard coal, the composition in coal combustion-promoting agents is not enough to impel hard coal better to burn; The flue gas of brown coal burning is comparatively large, and burning-point is low, uses existing ignition dope to coal firing boiler without effect of coal saving, and the lingemann blackness in more difficult reduction flue gas, and easily coking.In addition, the industrial chemicals in these coal combustion-promoting agents easily causes corrosion to boiler, shortens the work-ing life of boiler.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention is to provide that a kind of efficient combustion-supporting, coal saving rate are high, the Novel coal combustion improver of stable reaction, long action time.This ignition dope mixes in coal and uses, and can improve boiler thermal output, reduce soot emission, economize on coal, prolonged boiler work-ing life.
The technical scheme that the present invention takes is:
A kind of coal combustion-promoting agents, is prepared from by following raw material: potassium permanganate 1-2 part, ammonium nitrate 3-5 part, calcium chloride 5-8 part, magnesium nitrate 2-8 part, aluminum oxide 1-3 part, bicarbonate of ammonia 10-20 part, gac 20-30 part.
Further, a kind of coal combustion-promoting agents, is prepared from by following raw material: 1 part, potassium permanganate, 3 parts, ammonium nitrate, 5 parts, calcium chloride, magnesium nitrate 2 parts, 1 part, aluminum oxide, 10 parts, bicarbonate of ammonia, gac 20 parts.
Further, a kind of coal combustion-promoting agents, is prepared from by following raw material: 2 parts, potassium permanganate, 5 parts, ammonium nitrate, 8 parts, calcium chloride, magnesium nitrate 8 parts, 3 parts, aluminum oxide, 20 parts, bicarbonate of ammonia, gac 30 parts.
Production Flow Chart of the present invention is: take often kind of raw material, sends in pulverizer respectively and pulverizes, cross 60 mesh sieves, then mix by weight ratio, packaging into products.
During use, add in raw coal according to the ratio of 3-5 ‰.
The invention has the beneficial effects as follows: raw coal activates under the catalysis of potassium manganate, ammonium nitrate, calcium chloride, magnesium nitrate, aluminum oxide, reduce the point of ignition of raw coal, shorten the ignition time of raw coal, and bicarbonate of ammonia, gac are as raising agent, make to produce many spaces in the coal seam of boiler, be easy to oxygen and enter into coal seam, coal is fully contacted with oxygen, promote burning of coal, increase combustion efficacy, improve thermo-efficiency.
