Embodiment 1

[0030] The selected coal-fired additive composition and its mass ratio are as follows:

[0031] Potassium nitrate 28Kg; manganese dioxide 56Kg; potassium chlorate 54Kg; sodium nitrate 26Kg; ethylenediaminetetraacetic acid 40Kg; hexamethylenetetramine 18Kg; ammonium nitrate 30Kg; sodium carbonate 20Kg;

[0032] Select formula raw materials according to the above-mentioned energy-saving and environment-friendly coal-fired additives; grind the selected formula raw materials into powder through a grinder; mix the pulverized raw materials into 1000 parts of water, stir well, and leave for 24 hours to obtain the coal-fired additive stock solution.

Embodiment 2

[0034] The selected coal-fired additive composition and its mass ratio are as follows:

[0035] Potassium nitrate 28Kg; manganese dioxide 56Kg; potassium chlorate 54Kg; sodium nitrate 26Kg; ethylenediaminetetraacetic acid 40Kg; hexamethylenetetramine 18Kg; ammonium nitrate 30Kg; sodium carbonate 20Kg;

[0036] Potassium permanganate 34Kg can also be put into the above-mentioned coal combustion additive. Potassium permanganate is an oxidizing agent, which can be decomposed at different temperatures, so that coal can be fully burned at different temperatures.

[0037] Select formula raw materials according to the above-mentioned energy-saving and environment-friendly coal-fired additives; grind the selected formula raw materials into powder through a grinder; mix the pulverized raw materials into 1000 parts of water, stir well, and leave for 24 hours to obtain the coal-fired additive stock solution.

Embodiment 3

[0039] The selected coal-fired additive composition and its mass ratio are as follows:

[0040] Potassium nitrate 25Kg; manganese dioxide 60Kg; potassium chlorate 55Kg; sodium nitrate 25Kg; ethylenediaminetetraacetic acid 42Kg; hexamethylenetetramine 20Kg; ammonium nitrate 35Kg; sodium carbonate 25Kg;

[0041] Potassium permanganate 35Kg can also be put into the above-mentioned coal-fired additive composition.

[0042] Select formula raw materials according to the above-mentioned energy-saving and environment-friendly coal-fired additives; grind the selected formula raw materials into powder through a grinder; mix the pulverized raw materials into 1000 parts of water, stir well, and leave for 24 hours to obtain the coal-fired additive stock solution.

[0043] The stock solution of the coal-fired additive prepared according to the above method can be stored for 3 years without deterioration; the coal mixed with the coal-fired additive according to the above method can be stored...

Abstract

The invention discloses an energy-saving environmental protection fire coal additive, which comprises 20 to 36 portions of potassium nitrate, 40 to 60 portions of manganese dioxide, 40 to 60 portions of potassium chlorate, 20 to 38 portions of sodium nitrate, 30 to 50 portions of EDTA, 15 to 30 portions of hexamethylene tetramine, 25 to 35 portions of ammonium nitrate, 10 to 30 portions of sodium carbonate and 40 to 60 portions of peroxy calcium carbonate. The fire coal additive also comprises 25 to 45 portions potassium permanganate. The preparation method of the fire coal additive is that formula material is prepared according to the above energy-saving environmental protection fire coal additive; the chosen formula materials are grinded into powder by a grinder; the power-like materials are added with 1000-portion water and are homogenously stirred and placed for 24-hour. The fire coal additive is capable of promoting the combustion of the coal, and has dramatic sulfur-fixing and dust removal and energy-saving functions, lowers the carbon content of the slag, reduces the harmful gas and smoke dischange volume, saves the coal-fired consumption and improves the furnace thermal efficiency.

Description

technical field [0001] The invention relates to the technical field of resources and environment, in particular to an energy-saving and environment-friendly coal-fired additive and a preparation method thereof. Background technique [0002] Coal is the most important energy source in our country, and a large amount of harmful gas and soot are emitted from coal combustion, which has caused the typical soot-type pollution of our country's atmosphere. Statistics released by the State Environmental Protection Administration of China show that in 2003, the total emission of sulfur dioxide in waste gas was 21.587 million tons, and acid rain pollution was very serious. A large amount of sulfur dioxide emissions, high concentration of sulfur dioxide in the atmosphere and the formation of acid rain have seriously affected human health, destroyed the ecosystem, and caused great losses to industrial and agricultural production. Therefore, the control and treatment of sulfur dioxide em...
