Abstract
The assistant for coal burning furnace and kiln is prepared with sodium chloride, sodium carbonate, calcium oxide, potassium nitrate, ferrocene and iron oxide red as material. The assistant has excellent effects of increasing oxygen supply and raising coal burning efficiency, and its ferrocene can eliminate black smoke, prevent furnace from corrosion and increase the service life of furnace; its calcium oxide, sodium carbonate and potassium nitrate can react to fix sulfur and avoid decomposition of calcium sulfate; and its added nanometer level compounds can raise the desulfurizing and pollution reducing effect of the assistant.
Description
Technical field
The present invention relates to a kind of incrustation for reducing smog or not needing, or for be easy to remove the material that cigarette ash adds in fuel or fire, particularly a kind of assistant for coal burning furnace and kiln.
Technical background
Because the quality of ature of coal in combustion processes different variations can take place, ature of coal is poor more, combustion conditions is poor more, will make coal combustion insufficient, so that wastes a large amount of energy, on the other hand, burn inadequate coal produce a large amount of obnoxious flavoures again severe contamination air.In order to change this situation, people usually add some auxiliary agents in burner aborning, burn jointly with fire coal, so that fire coal can burn as far as possible, improve coal-fired efficiency of combustion.But present big manifold coal furnace auxiliary agent, it often has effect preferably aspect combustion-supporting, but aspect the removal obnoxious flavour, also but effect is bad with regard to the purifying air aspect, and the professional equipment that also needs to be equipped with other carries out purifying treatment.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part and provide a kind of and promptly have good combustion-supporting effect, have good desulfurization, the coal furnace auxiliary agent of decoking, reduction noxious gas emission.
A kind of assistant for coal burning furnace and kiln is characterized in that: described coal furnace auxiliary agent contains 30%-50% (weight) sodium-chlor, 15%-20% (weight) yellow soda ash, 5%-10% (weight) calcium oxide, 5%-15% (weight) saltpetre, 1%-5% (weight) ferrocene, 5%-15% (weight) red iron oxide.
Coal furnace auxiliary agent of the present invention, sodium-chlor in its prescription, yellow soda ash, saltpetre is alkaline metal oxide, their chemically reactives are very strong, the generation transition that is activated easily of their atom outermost electron, it is fast to emit a large amount of electron radiation energy and its release rate in transition process, generation heat height, the raising boiler temperature is highly advantageous to, play good combustion-supporting effect, simultaneously because sodium-chlor can prolong the residence time of sulfurous gas in stove, thereby suppress the discharging of sulfurous gas, and sodium-chlor can also reduce the point of ignition of catalysis coal, play good combustion-supporting effect, simultaneously because it can decompose generation " microexplosion " in incendiary moment, a burnt grain surface combustion product is comparatively fast broken away from, and form " attacking a vital point ", thereby be beneficial to combustion air flowing and improve coking in stove at reflecting point.Calcium oxide in the prescription, it can be used as sulphur-fixing agent usually and uses, but because the calcium sulfate that is in use produced can at high temperature decompose, reduced the effect of solid sulphur on the contrary again, this prescription has also added yellow soda ash, these alkaline metal oxides of saltpetre when adding calcium oxide, these metal oxides can resist the pyrolytic decomposition of calcium sulfate, thereby improve the captured sulfur result of calcium oxide greatly.Simultaneously because the present invention has also added ferrocene as synergistic agent in prescription, it can eliminate the black smoke that coal-fired incomplete combustion produces, reduce the carbon content in the slag, simultaneously because the ferric oxide that its burning back generates belongs to oxygenant, under hot conditions, they can carry out redox reaction to the carbon monoxide in the roasting kiln as reductive agent, make reaction of carbon monoxide become carbonic acid gas, thereby reduce carbon monoxide content in the flue gas.The ferric oxide of its generation simultaneously also can be had an effect jointly with the red iron oxide in the prescription, to suppress the corrosion of roasting kiln, plays the effect of protection roasting kiln, thus the work-ing life that can improve roasting kiln.
Coal furnace auxiliary agent of the present invention can method routinely process.
Described red iron oxide is natural red iron oxide.
Also contain the nano level calcium oxide of 0.2%-0.5% (weight) in the described coal furnace auxiliary agent.
The specificity that the compound of nano shape itself is had can make in the coal, sulphur and the abundant chemical combination of calcium oxide in the low grade coal especially, thereby desulfurization degree can be reached more than 70%, thereby makes auxiliary agent of the present invention have splendid sweetening effectiveness.
Also contain 0.1%-0.3% (weight) cobalt titanate in the described coal furnace auxiliary agent.
Cobalt titanate is a kind of good desulfurization catalyst, and it can promote sulphur and the abundant chemical combination of calcium oxide in the coal.
Described metatitanic acid bores and is the cobalt titanate of sodium meter level.
The invention has the advantages that:
Because the present invention has added ferrocene as synergistic agent in prescription, it has not only played the effect of eliminating black smoke, also can react with the carbon monoxide in the roasting kiln simultaneously owing to it, therefore can not only reduce the carbon monoxide in the flue gas, and its production thing can also play the work-ing life that the inhibition roasting kiln was corroded, prolonged roasting kiln; This prescription has also added the calcium oxide sulphur-fixing agent simultaneously, that utilizes calcium oxide and alkaline metal oxides such as yellow soda ash makes usefulness mutually mutually, improved the solid sulphur effect of calcium oxide, the present invention is owing to also adopted the compound of sodium meter level, thereby can utilize the specificity of sodium meter level compound, improve the desulfurization degree of this auxiliary agent.Ignition dope of the present invention can manually directly be poured powder in boiler coal feeding machine negative pressure mouth or the pulverizing mill into.Other kiln then can connect pouch and be thrown into the prosperous strong district of burning together from manhole door with packed powder, therefore uses convenience extremely.Simultaneously auxiliary agent initial content of the present invention is 2/10000ths of a consumption of coal only seldom, after stable, then consumption of coal more can be reduced to ten thousand/.
