CN102212405A - Coal-saving catalytic synergistic agent - Google Patents

Abstract

The invention relates to a coal combustion-supporting agent, in particular to a coal-saving catalytic synergistic agent which is suitable for different types of coal-fired boilers, can support combustion, save energy and inhibit harmful substances such as smoke, sulfur dioxide and the like from discharging. The coal-saving catalytic synergistic agent is prepared by the following five steps of: weighing ferric oxide, manganese dioxide, active carbon, borax, potassium nitrate, ammonium nitrate, magnesium nitrate, chlorate and light calcium carbonate according to the proportions, putting the weighed raw materials into a pulverizing mill, pulverizing, drying and stirring. The coal combustion-supporting agent has the double characteristics of energy saving and environment friendliness.

Description

The catalytic synergist of economizing on coal

Technical field

The present invention relates to a kind of coal combustion-promoting agents, in particular, it relate to a kind of be applicable to dissimilar coal firing boilers can combustion-supporting and energy-saving, suppress the catalytic synergist of economizing on coal of discharge of poisonous waste such as flue dust, sulfurous gas.

Background technology

At present, the production of China's energy and consumption all are based on coal, wherein be used for energy incendiary coal and account for 98% of energy extraction total amount, this numeral is also constantly increasing every year, coal is cannot regenerated fuel, excessive exploitation and irrational burning are used, and all can cause great waste to the coal resources of China.In the process of coal burning,, form topsoil because not thorough, the insufficient loss that causes a large amount of energy of coal burning does not also have the obnoxious flavour of after-flame to be discharged in the air simultaneously yet thereupon.Have again in the coal firing boiler combustion processes, because the ature of coal ash content is big, factor such as thermal value is low, the coking and slagging phenomenon often appears in boiler, and boiler spray combustion mouthful is blocked when serious, causes a large amount of dust stratifications easily, and it is unfavorable greatly to bring to safety in production.Therefore, occurred some on the market thereupon and be used for combustion-supporting additive, these additives have played combustion-supporting effect to a certain extent in the process of coal burning, but effect is not very desirable, and the cost that has is very high, environmental protection but not energy-conservation and complex manufacturing.

Summary of the invention

The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of catalytic synergist of economizing on coal with energy-saving and environmental protection dual characteristics is provided.

In order to achieve the above object, the present invention is achieved in that the catalytic synergist of economizing on coal is made up of ferric oxide, Manganse Dioxide, gac, borax, saltpetre, ammonium nitrate, magnesium nitrate, oxymuriate, light calcium carbonate.Its raw material consumption mass ratio is:

Ferric oxide 6%-9%

Manganse Dioxide 9%-11%

Gac 10%-12%

Borax 10%-14%

Saltpetre 14%-17%

Ammonium nitrate 10%-15%

Magnesium nitrate 13%-16%

Oxymuriate 9%-11%

Light calcium carbonate 5%-8%

Above-mentioned ferric oxide and Manganse Dioxide are as the reductive agent composition of this catalytic synergist of economizing on coal; Above-mentioned gac and borax are as the sorbent material composition of this catalytic synergist of economizing on coal; Above-mentioned saltpetre and ammonium nitrate are as the ignition dope composition of this catalytic synergist of economizing on coal; Above-mentioned magnesium nitrate and oxymuriate are as this catalytic synergist catalyst component of economizing on coal; Above-mentioned light calcium carbonate is as the raising agent composition of this catalytic synergist of economizing on coal.

After adopting such scheme, the invention has the beneficial effects as follows: by catalytic activation, absorbing and reducing, follow-up oxygen exchange combustion-supportingly, and chemical reaction can reach solid sulphur and reduce discharging, deashing coke cleaning, catalytic combustion-supporting, the effect of saving fire coal.Coal saving rate is between 5%-16%, and its consumption is 3/10000ths.

Embodiment

Example 1

The present invention's catalytic synergist of economizing on coal, form by following materials in percentage by mass:

Ferric oxide 9%

Manganse Dioxide 11%

Gac 112%

Borax 10%

Saltpetre 15%

Ammonium nitrate 10%

Magnesium nitrate 15%

Oxymuriate 11%

Light calcium carbonate 5%

In this embodiment, after above-mentioned industrial chemicals mixed, after putting into pulverizer and being crushed to the powder that the 100-120 order obtains, again powder is put into dryer and dry, put into stirrer afterwards again and stir.
