Abstract
The invention relates to a preparation method of a fire coal improver. After a fire coal additive is added into ordinary fire coal for burning, remarkable and effective energy-saving and emission-reducing effects can be achieved. Firstly, white polylol hexanediol in a solid state is adopted, polylol is added to enhance a combustion supporting function, the polylol hexanediol is prepared into a solid fire coal combustion improver together with other aids, and convenience is brought to transport and storage; secondly, sodium acetate serving as a swelling agent is introduced for performing base exchange with humate in coal to generate humate with a low fire point, so that the ignitability of coal is reduced; and thirdly, ferric oxide needed in a formula is a water-dissoluble compound, so that ferric oxide is generated by making ferric chloride and calcium oxide react in a water adding dissolving process in the invention, and the preparation and application characteristics of the three compounds are not possessed by other products on the market.
Description
Technical field
The present invention relates to a kind of preparation method of combustion-supporting agent for fuel coal.Common fire coal is after adding the combustion-supporting agent for fuel coal burning, but obvious and effective reaches the effect of energy-saving and emission-reduction.
Background technology
Along with China's economy continues to develop rapidly, urbanization process is accelerated, and population constantly increases, and coal year, consumption was year by year to increase considerably.Coal combustion is the main mode of coal utilization, and China's energy structure mainly is based on coal, is used for direct incendiary coal every year and is about 800,000,000 tons.Environment is caused serious pollution.China use coal and the Global warming gas that produces may surpass all industrialized countries at following 25 years the common amount that produces, exceed five times than the standard of Kyoto Protocol.
In sum, how to utilize resource efficiently and reduce pollution to greatest extent, become the urgent task of pendulum in face of ours.Therefore, develop a kind of combustion-supporting agent for fuel coal and become first-selection.Combustion-supporting agent for fuel coal has following different with present commercially available additive:
One, combustion-supporting agent for fuel coal is different with the mechanism of action of other additive for fire coal, and combustion-supporting agent for fuel coal is according to burning of coal essence; And the effective catalyst of the free radical type of developing in conjunction with actual combustion processes; At the coal cinder of some larger particles, the process that oxygen enters coal is comprised that the multiple factor affecting of coking is comparatively slow, and the part coal burning time is shorter, is not enough to guarantee to reach abundant burning, and this is the high major cause of boiler slag carbon content.Add the strong osmotic power effect suction additive that has the dispersion agent of emulsifying property in the adsorption that utilizes coal itself behind the combustion-supporting agent for fuel coal and the additive.Utilizing catalyzer in the additive to make during coal burning coal-firedly is in about 200 ℃ of fire box temperatures begin to 700 ℃ among the strong cartalytic decomposition effect entering, can progressively emit the combustion-supporting inside of active oxygen and produce some microexplosions and impel coal to break along with temperature raises again, allow the coal of more ratios enter the dynamic combustion state from the diffusion combustion state at coal.Thereby make coal burning complete;
Two, economy is remarkable, and that combustion-supporting agent for fuel coal can play is combustion-supporting strongly, energization, the effect of economizing on coal, but coal saving rate 5%～15% after tested, furnace temperature raises 50～80 ℃, and lime-ash carbon containing reduction rate is more than 26%, desulfurization degree about 60%.Economic benefit is considerable;
Three, the ignition dope hexylene glycol in the combustion-supporting agent for fuel coal is to contain the polyvalent alcohol that enriches carbochain.Be the white solid state, be convenient to transportation and storage.Therefore combustion-supporting agent for fuel coal occurs as commodity with solid state, has so just reduced transportation cost.This is that other products do not possess on the market.
Four, burning of coal exists a series of problem: the calorific value of coal utilizes low, and reason is that its thermal capacitance is big, burning-point is high, is difficult for catching fire and conducting heat.Its basic elementary reaction C+O
2-----→ CO
2Activation energy big, and side reaction CO easily takes place
2+ C-----→ 2CO makes thermo-efficiency descend greatly.Thereby add metallic salt and metal oxide, and can reduce the thermal capacitance of coal to a certain extent, increase thermal conduction, help improving intensity of combustion.Ferric oxide among the present invention, Manganse Dioxide effect promptly are this.
