Abstract
The present invention is a kind of decoking coal-saving comburant: it is characterized in that being made up of chromic anhydride, copper chloride, manganese dioxide, Vermiculitum, fluorite, aluminium oxide, activated magnesia, active calcium oxide and nickel oxide, this combustion adjuvant, it not be used in boiler and spray coke-removing agent, decrease the trouble of decoking, boiler thermal output about 1 3% can be improved, there are extremely strong economic benefits.
Description
Technical field
The present invention relates to a kind of decoking coal-saving comburant.
Background technology
All the time, the fuel of China all contains substantial amounts of sulfur and other dirts, when forming substantial amounts of noxious substance after burning, after this kind of material encounters heat exchanger, substantial amounts of sulfate and sulphite can be formed on the surface of boiler, these materials have extremely strong corrosivity, eventually the surface at boiler forms substantial amounts of slag, thus affect the service life of boiler, reduce hot utilization rate, after the slag formed deposits in a large number, Automatic-falling can be caused to cause fire extinguishing, blowing out, even causes danger.
Summary of the invention
The present invention is aiming at the problems referred to above, one decoking coal-saving comburant is provided, it is made up of chromic anhydride, copper chloride, manganese dioxide, Vermiculitum, fluorite, aluminium oxide, activated magnesia, active calcium oxide and nickel oxide, the quality proportioning of above-mentioned substance is: chromic anhydride 15-30, copper chloride 5-15, manganese dioxide 10-20, Vermiculitum 10-20, fluorite 5-10, aluminium oxide 5-15, activated magnesia 5-15, active calcium oxide 5-10, nickel oxide 5-15.
The quality proportioning of described material is: chromic anhydride 20, copper chloride 10, and manganese dioxide 15, Vermiculitum 15, fluorite 5, aluminium oxide 10, activated magnesia 10, active oxygen are than calcium 5, nickel oxide 10.
One prepares decoking coal-saving comburant preparation method, comprises the following steps:
Step one: dispensing, according to chromic anhydride 20, copper chloride 10, various raw materials are added in drum agitation device by manganese dioxide 15, Vermiculitum 15, fluorite 5, aluminium oxide 10, activated magnesia 10, active calcium oxide 5, the proportioning of nickel oxide 10 by loader；
Step 2: stirring, starts agitator, is sufficiently mixed 15 minutes, and the material after being stirred is put in automatic filling machine；
Step 3: check, pack, put in storage.
1, slag-removing ash-cleaning mechanism: this product is suited the remedy to the case from slag-bonding mechanism, to improve coal ash fusion temperature, for the purpose of coal ash viscosity, containing meeting the chromium material promoting that slag type is changed to crystalline state slag type by glassy state, make chromium ion aluminosilicate in ash component be combined, constantly iron ion is formed high temperature mineral group's network with endoplasm with as addition (the high ferrous components in ash).Its molten solubility temperature is between 1380～1440 DEG C, and when product i.e. high temperature material flies to burner hearth tube wall, they have located solidification or half curdled appearance, so the slag body of heterogeneous body will not be generated.Solve the problem that the home and abroad prior art products suitability is little, comprehensive function by each composition, can reach effect that various coal-fired ash fusion points, ash viscosity, slagging scorification type, sedimentation are all significantly increased, it is ensured that the coal dust boiler with dry bottom furnace safety and economic operation long-acting cycle.(raising ash fusion point 80～220 DEG C, viscosity 10～30 times).
2, Energy saving mechanism: in stove in specific burning situation, the continuous interpolation of chromium material, due to the effect of high temeperature chemistry fission catalysis, the oxygen atom generated has huge heat energy, burner hearth central temperature can be made to improve 80～140 DEG C, hence it is evident that improve coal vapour ratio, coal saving rate is notable (up to 5-12%).Start the frontier using high temeperature chemistry fission catalyst mechanism principle energy-saving and cost-reducing.
3, corrosion-free side effect: get rid of and use industrial table salt and water-soluble potassium, the use of sodium salt in existing deslagging agent, prevent its high and low temperature flue gas corrosion to boiler.Through Xi'an thermal technology institute to boiler chromium-base slag-removing ash-cleaning joint agent in 12CrlMoV rustless steel and the high temperature corrosion effect of 20# steel boiler, result shows to show near-space white value, effect corrosion-free to boiler.
4, this product chromio removes (preventing) slag agent, is similar to maximally effective product in American-European deslagging agent, and its anti-scorch performance that removes the gred is far above same kind of products at abroad performance.This agent not only removes the coke heavy of furnace combustion zone, and significantly reduces the dust stratification of height superheater, and can reduce fly ash combustible material, and exhaust gas temperature tends to normal range, and coke heavy dust stratification boiler can be improved boiler thermal output about 1-3%
