4) etc.These mineral substance are grey shape, hard scale shape, molten shape, impel boiler thermal output to descend greatly, and energy consumption increases, and erode metallic surfaces shortens boiler work-ing life etc.More than these problems can have a strong impact on boiler safety, economical operation.
Before the present invention makes, have in the technology,, normally adopt the artificial deashing of blowing out, decoking or with two kinds of methods of chemical dust-cleaning agent deashing, the decoking on Industrial Boiler, the power station boiler of power plant in the sixth of the twelve Earthly Branches.Artificial deashing, decoking but can't be removed boiler radiation heating surface back and convection heating surface back, and therefore, it is undesirable manually to remove effect.Another kind method is chemical dust-cleaning agent.Chinese patent application number: 94110396.7 disclose a kind of dust-cleaning agent for boiler, and it mainly is mixed and made into by salt, aluminium powder, borax, iron oxide red, quartz yarn and soda ash etc.This dust-cleaning agent can only deashing and can not decoking, therefore, can not satisfy user's service requirements.
Summary of the invention:
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of nontoxic, efficient, can rapidly mineral substance be loosened, come off, drain with air inducing; Can deashing again can decoking, thereby make the boiler can trouble-free burning, improved thermo-efficiency, can energy efficient, and can prolonged boiler the high-performance energy-saving rare earth ash-cleaning and coke-removing agent in work-ing life.
It is simple, easy to use that another kind of purpose of the present invention provides a kind of operation steps, the production method of safe and reliable high-performance energy-saving rare earth removing ash of boiler decoking agent.
Main solution of the present invention is achieved in that
Removing ash of boiler decoking agent of the present invention adopts following component to be re-dubbed, and its component content is by (weight percentage): the present invention gets nitrate and is: 35～60%, cerium oxide is: 10～15%, Neodymium trioxide is: 5～10%, borax is: 5～10%, yellow soda ash is: 5～10%, sodium-chlor is: 5～8%, lime carbonate is: 5～8%, magnesium oxide is: 3～5%; The screening of above-mentioned component weighed after mix, congruent melting, drying, granulation, verify as finished product.
Production method of the present invention adopts following processing step: its component content is by (weight percentage):
1, the present invention gets nitrate and is: 35～60%, cerium oxide is: 10～15%, Neodymium trioxide is: 5～10%, borax is: 5～10%, yellow soda ash is: 5～10%, sodium-chlor is: 5～8%, lime carbonate is: 5～8%, magnesium oxide is: 3～5%; Add mixing and stirring in the stirrer, stirrer rotating speed: 40～20 rev/mins;
2, mixture after being mixed is carried out congruent melting, eutectic temperature is: 50～80 ℃, the congruent melting time is 2～3 hours;
3, carry out drying treatment after the mixture congruent melting, drying temperature is: 60～150 ℃, be time of drying: 2～3 minutes; It is particulate state that mixture after drying carries out granulation, and particle diameter is: 1～3mm;
4, after verify as finished product, the packing warehouse-in.
Compared with the prior art the present invention has the following advantages:
1, after this product is sent into high-temperature burner hearth, through high-temp combustion, promptly with the metallic surface on dirt, coking, produce physics chemical action, the slagging scorification that makes the extremely strong vitriol of corrodibility, sulphite and oxide compound is from slightly acidic (PH
4) become weakly alkaline, rapidly with crock, loosen, come off, drain with air inducing, and can prevent to generate new crock, allow the boiler trouble-free burning thereby reach, improved thermo-efficiency, can energy efficient, but and prolonged boiler work-ing life;
2, under the situation of ature of coal burning difference, add this product, drop into when participating in burning in the stove, decompose step by step and generate multiple stronger oxygenant and catalyzer, discharge a large amount of oxygen simultaneously, play strong combustion-supporting effect, the removal (making the abundant after-flame of coal) of carbon and carbide in the promotion flue gas; Can also produce chemical reaction with the crock on the heating surface in addition, make carbon and carbide in the crock become carbonoxide and carbonic acid gas volatilization, reduced the content of carbon and carbon compound in the flue gas, reach the purpose of smoke elimination, dedusting, combustion-supporting, desulfurization, thereby improve the efficient of boiler, reduce boiler coal consumption, reduce lingemann blackness;
3, nontoxic, efficient, can deashing, again can decoking, to the grease on the oil-firing boiler, oil coke, it is obvious to remove effect;
4, be raw material owing to the present invention has adopted rare earth material, with high content of technology, consumption is few, energy-conservation cost height, easy to use, user satisfaction is high, consumption is 5/10000ths of a day combustion amount, through adjusting annual minimum can save energy about 5800～6800 yuan of each evaporation tonnage of boiler, its social benefit and economic benefit make very remarkable;
5, can reduce topsoil, help environmental health.
