Description
Technical field
The present invention relates to a kind of catalytic combustion-supporting coal-saving additive, belong to the additive for fire coal technical field.
Background technology
Energy scarcity has become the No.1 problem in the world at present, though China is coal reserves big country, because Economic development is rapid, energy consumption increases substantially, and the exploitation of coal and use have produced contradiction.Coal burning is insufficient also to have caused great pollution to surrounding environment with a large amount of obnoxious flavour of burning back generation.Along with energy-conservation and continuous enhancing environmental consciousness, save energy, protection environment have become enterprise and have reduced production costs, strengthened one of effective means of product market competitiveness.
Because China's rapid economic development in recent years, dwarf boiler are replaced by large-sized boiler, critical and super critical boiler gradually, therefore also need new technology to satisfy the demand of modern boiler.
Present catalysis coal-saving additive is a lot, and catalyzer adopts ferrocene more, but because ferrocene is water insoluble, most catalysis coal-saving additives adopt pulvis, have poor stability, mixes inhomogeneously with coal dust, measures inaccurate shortcoming.
Summary of the invention
The object of the present invention is to provide a kind of concentration high, excellent catalytic effect is easy to the blended catalytic combustion-supporting coal-saving additive.
Technical scheme of the present invention is following:
Catalytic combustion-supporting coal-saving additive of the present invention is characterized in that containing the aqueous solution that weight percent is 10～25% carboxyl ferrocene.The percentage composition of described carboxyl ferrocene most preferably is 15～20% the aqueous solution
The catalytic combustion-supporting coal-saving additive of the invention described above in order further to improve catalytic effect, also contains following raw materials by weight percent: 1～5% permeate agent OT, 2～10%Ce (NO
3)
2, 10～25%NaClO
3, 1～5% penetrating agent JFC, 2～10%NaNO

Described carboxyl ferrocene can be divided into two kinds of a carboxyl ferrocene and dicarboxyl ferrocene.Described carboxyl ferrocene is also referred to as ferrocenecarboxylic acid, is divided into ferrocenecarboxylic acid, ferrocene acetate and ferrocene propionic acid.
Know-why of the present invention:
Catalytic combustion-supporting coal-saving additive of the present invention develops according to the flame mechanism of coal in the stove hall.Combustion processes is the process of a complicacy, comprises igniting and burn two stages, but in brief; Also be the process of Geju City chemical bond rupture and new key formation, this process is a chain type radical process, and this process is carried out fully more; Efficiency of combustion is just high more; With regard to condition being provided,, will obtain higher boiler efficiency if keep high heat transfer efficient and low-heat loss again for obtaining high boiler efficiency.
In view of the above, the mainly effect of outstanding following several respects of the research and development of catalytic combustion-supporting coal-saving additive of the present invention:
The firstth, katalysis.This agent is heated and can be discharged a large amount of high energy radicals, interrupts oxygen-oxygen three key rapidly and fast reaction speed;
The secondth, the oxygenation effect.This agent is heated and is understood the release oxygen atom, and these Sauerstoffatoms need not spread and directly contact carbon nuclear, has saved this controlled step of diffusion, thereby has accelerated combustionvelocity;
The 3rd is the liberation of hydrogen effect.This agent is closed with oxidation behind the carbon grain surface liberation of hydrogen, produces small high temperature oxyhydrogen flame, has accelerated combustion speed thereby improved the carbon grain surface temperature;
The 4th is the microexplosion effect.The meeting of separating out of gas produces differential expansion and carbon grain surface is broken, thereby increases the heterogeneous proportion that ignites, and making ignites speeds up;
The 5th is peace and quiet effect.Small amounts of medicament arrives water wall decomposes, and can make the adsorptive surface of adhering on the water wall produce loose and defective, and becoming is easy to come off.
More than the general effect of effect generation is to catch fire and the combustionvelocity quickening, and after-burning reduces, and heat loss due to exhaust gas reduces, and can keep higher heat transfer efficiency, for the high efficiency boiler operation provides the technical measures that can supply adopt.
Catalytic combustion-supporting coal-saving additive of the present invention has following function
1, improve fire box temperature, increase rate is different and different with coal with the type of furnace;
2, reduce funnel temperature;
3, reduce the heat-transfer surface coking;
4, coal saving rate remains between 2-20% with the difference of the type of furnace, coal, operating duty and boiler purposes;
5, reduce fume emission in proportion with coal saving rate;
6, save coal supply and air-supply power in proportion.
Catalytic combustion-supporting coal-saving additive of the present invention is compared with currently available products, has following outstanding effect: catalytic combustion-supporting coal-saving additive of the present invention is an aqua, and therefore non-inflammable explosive article uses and go up no potential safety hazard; This agent pH value is 8.5, and metal without acid is lost; This agent degradation production is neutral, and equipment is not had corrosion; The products of combustion of this agent degradation production is neutral oxide, and is harmless to equipment; This agent is pure liquid state, is prone to realize evenly adding synchronously with coal supply; This agent has the concentration height, the advantage of excellent catalytic effect.
Embodiment
1. the proportioning by table 1 prepares catalytic combustion-supporting coal-saving additive of the present invention.
Concrete preparation method is:
1, the preparation of catalyzer carboxyl ferrocene: make negative electrode with nickel, iron is made anode, and ethanol is solvent, logical 32V direct current electrolysis; Electric current 2000A stopped electrolysis in 3 hours, and to add Louis alkali be catalyzer and add the monocycle pentadiene and 2-chlorinated carboxylic acid sodium; Stirred 1 hour, and used water washing and precipitating behind the elimination solvent, a little insolubles is discarded; Washing lotion is gone into reaction kettle, processes to contain ferrocenecarboxylic acid the mixture of ferrocene acetate and ferrocene propionic acid.
2, the carboxyl ferrocene changes over to instead and just adds enough required water in the still in proportion;
3, open and stir and under constantly stirring, adding NaNO successively
3, Ce (NO
3)
2, NaClO
3, JFC, permeate agent OT.
4, continue to stir 30min, stop stirring packing.
Attention: reply reaction kettle heating when temperature is lower than 20 ℃, 30 ℃ of still temperature.
Concrete method of use: in accounting for the raw coal weight ratio is 7/10000ths ratio, and above-mentioned catalytic combustion-supporting coal-saving additive is mixed with raw coal.Distribution: summer temperature is high, can evenly add in the coal as former dose, can dilute or multiple that dilute with water is less uses; Winter temperature is low, separates out for anti-solid working substance, should dilute the back and add; No matter summer in winter, its Dilution ratio is exceeded to be no more than 5 times.For chain furnace, see that the user confirms water consumption with the degree of drying of coal.Add the agent mode, pump into or the header tank gravity flow, add agent flux and last coal or coal-supplying amount and realize synchronously control automatically.
2. to adopt 3.5% ferrocene be catalyzer to the additive of contrast test example, and other raw material is: 3% permeate agent OT, 8%Ce (NO
