Abstract
The present invention discloses an additive agent (a Xulun powder) for furnaces, which is composed of potassium nitrate, a sodium nitrate complex compound (KNO3NaNO3), sodium (Potassium) carbonate, sodium (potassium) chloride, gamma-ferric oxide, aluminum oxide, silicon oxide and silicon oxide. The present invention has the effects of promoting the combustion of free carbon in tar and inferior coal, loosening soot coke and changing the properties of the soot coke so as to desquamate the soot coke, raising the efficiency of thermal conductance of the combustion furnace, saving energy, reducing pollution, reducing the corrosion rate of the combustion furnace, etc., and can be widely applied to various combustion furnaces burning agglomerate coal and powder coal or oil.
Description
The present invention relates to a kind ofly reduce smog and the settling that do not need or be easy to remove cigarette ash and the additive that in fuel or fire, adds.
Burn when bunker coal, oil drop in the stove, decomposite materials such as volatile combustible hydrocarbon polymer, hydrogen, enter the prosperous strong stage of burning.But afterwards often because air capacity is under-supply, and volatile matter is difficult for after-flame in the fuel, and be decomposed into thing such as uncombined carbon tar, form coking and fouling, black smoke and carbon monoxide, dusty gass such as various sulfur oxides, nitrogen oxide.Efficiency of combustion is reduced, and the calorific value of fuel fails to give full play to, and causes energy dissipation.The ignition dope of domestic and foreign literature report, the coke-knocking descaling agent, though sweetening agent etc. are various in style, practical application is all undesirable.As the disclosed a kind of fuel dope of Japanese Patent JP58164696 (nineteen eighty-three), it is by silicon-dioxide diatomite, and magnesium oxide and ferric oxide are mixed and made into, complex manufacturing, and the cost height uses enterprise to be difficult to bear.
The object of the present invention is to provide the kiln additive of a kind of roasting kiln efficient combustion-supporting, energy coke-knocking descaling, reduction toxic gas quantity discharged.
Technical solution of the present invention is:
A kind of kiln additive (having another name called thread human relations powder), the difference of itself and prior art is: be made up of weight components:
Saltpetre SODIUMNITRATE complex compound (KNO3.NaNO
3) 10-22%
Yellow soda ash (or salt of wormwood) 23-49%
Sodium-chlor (or Repone K) 20-45%
R-ferric oxide 1-5%
Silicon oxide 6-21%
This additive is to have the light red pressed powder that particle diameter is the 0.10-0.45 millimeter.
The manufacturing of additive of the present invention (thread human relations powder) is to carry out according to a conventional method.At first with the each component raw material drying, by mechanical disintegration, prepare burden by proportioning more respectively, after stirring is mixed, screen, getting particle diameter is the light red pressed powder of 0.10-0.45mm, is product.
Production technique of the present invention is simple, cost is low, and product is non-explosive type pressed powder, safety, package stability height.
Because additive of the present invention has adopted rational formula, therefore have efficient combustion-supporting, coke-knocking descaling, reduce multiple functions such as harmful gas emission, be applicable to the various roasting kilns of burning lumped coal, powder coal or oil, safety easy to use, its superiority is fairly obvious, is in particular in:
1, combustion-supporting additive of the present invention has tar and the combustion-supporting effect of low grade coal.Because oxygenation effect, make the carbon part ratio of combustion in tar and the low grade coal more complete, cause aflame carbon and hydrocarbons residual particles to reduce, make the ash content component trend standard in the slag, ash melting point reduces, slag adhesion slagging scorification situation makes moderate progress, and molten Jie's degree of ashes also can correspondingly improve simultaneously, helps environment protection treating.
2, after coke-knocking descaling drops into additive in roasting kiln, not only can avoid newborn cigarette ash coking and fouling to produce, and the hard old burnt incrustation of not removing for a long time can make it progressively come off after using additive of the present invention.Because features high scale-removing effect has also reduced the blowing out number of times, reduces fireman's labour intensity greatly.
3, energy-conservation owing to removed low burnt dirt, the crock of thermal conductivity, directly raising burning thermal conductance efficient reduces thermosteresis, thereby has saved the energy, and boiler unit's steam consumption of coal is lowered.
4, reduce harmful gas emission, reduced environmental pollution, also slowed down the corrosion of roasting kiln, prolong the work-ing life of roasting kiln greatly.
5, not only production technique is simple for additive of the present invention easy to use, and cost is low, and consumption is few, and safety easy to use is effective.With ten thousand of consumption of coal/ directly add in the stove from negative pressure mouth or material inlet, needn't mix thoroughly with fuel, added once in 8 hours at interval, add every day three times.
The utility model is described in further detail below in conjunction with embodiment:
Embodiment 1-6:
With the each component drying, make water content less than 5%, pass through mechanical disintegration more respectively, make particle diameter reach the 0.10-0.45 millimeter, proportioning by following each embodiment is prepared burden, after mixing, screen, getting particle diameter is light red pressed powder additive (the thread human relations powder) product of 0.10-0.45 millimeter.
