Abstract

The invention discloses a kind of dynamical coal-saving additive.It is by the high dispersive hypertonicity, make the additive high dispersing and be penetrated in the coal, effect by catalyzer, not only reduced the required activation energy of coal burning, reduced the point of ignition of coal, combustionvelocity is accelerated, and catalysis of the present invention and permeate agent also have combustion-supporting effect simultaneously makes coal burning more abundant, thereby reaches the effect that eliminates smoke and economize on coal.Its coal saving rate: chain furnace and cement in vertical kiln 10～25%, circulating fluid-bed 6～10%, coal-powder boiler 5～8%.

Description

High efficiency environment-friendly coal saving agent

The present invention is coal-fired fluid additive, is mainly used in the catalytic combustion-supporting of steam coal, to reach the purpose of the consumption reduction that eliminates smoke.

The global energy is exhausted day by day, and coal equally belongs to the non-renewable energy with oil, saves and make full use of coal, and the protection environment is the target of making joint efforts in the whole world, and the exploitation coal-saving agent only is one of measure wherein.In numerous coal-saving additives, solid phase prod is in the majority, has adopted some strong oxidizers or their mixture mostly, and because addition is big, use is inconvenient, is difficult to practical application.Though the liquid section coal additive all has report in states such as the U.S., Japan, Canada, Korea S, China, exist result of use and the not good problem of stability.

Purpose of the present invention just is to provide a kind of catalysis, combustion-supporting, disperse, the optimum combination of permeate agent etc., make it when coal burning, can reduce the required activation energy of burning, thereby reduced the point of ignition of coal, in fact saved a part of energy consumption that coal is warming up to kindling temperature, because the comprehensive action of coal-saving agent, coal is expanded in the incendiary process, the coal seam raises, just as fermentation, make air accelerate circulation, it is more abundant to burn, and this is more clear than the effect that adds the small amounts agent, its result just makes the carbon content in the residue reduce greatly, thereby has reached smoke elimination, the effect of economizing on coal.The abundant burning of coal raises the temperature in the stove, and the free charcoal amount significantly reduces, and the furnace wall does not only have new coking, and original coking also can progressively come off, and the thermo-efficiency of boiler is further improved, and ton coal steam production obviously improves, and the efficient of economizing on coal is apparent.Therefore, the coal saving rate of coal-saving agent of the present invention has comprised two aspects, and one is to have added coal less, and another has been voluminous vapour.

Coal-saving additive of the present invention is characterized in that it forms (W/W) by following prescription: catalysis burning-rate accelerator 1～10%, and promotor 0～5%, infiltration ignition dope 35～80%, dispersion agent 2～20%, stablizer 2～20% is formed.

Catalysis burning-rate accelerator is originally as high energy fuels: they can be 1,1 '-diethyl ferrocene, butyl ferrocene, 4,4-two (ferrocenyl)-1-amylalcohol, 2, two (ethyl dicyclopentadienyl iron) propane of 2-, two silica methyl ferrocene etc. also can be wherein several mixtures.Promotor is calcium naphthenate, zinc naphthenate, cobalt naphthenate, copper naphthenate, manganese naphthenate, nickel naphthenate etc.The infiltration ignition dope is a micromolecular water.Dispersion agent is the compound of negatively charged ion and nonionogenic tenside; anion surfactant can be alkyl-sulphate, alkylbenzene sulfonate, sulfonated alkyl naphathalene, dialkyl group Succinic Acid sulfonate, alkylamide taurate, aliphatic alcohol polyoxyethylene sulfonate etc., and nonionogenic tenside can be alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, fatty alcohol-polyoxyethylene ether methyl-monosilane, polyoxyethylene-polyoxypropylene block type polyethers, sucrose fatty acid ester etc.Stablizer is Xylo-Mucine, sodium alginate, calcium lignin sulphonate etc.
