Embodiment 1

[0015] Embodiment one: Type A value-added agent:

[0016] Oil shale 68-81%, humic acid 10-15%, acidified gangue 2-6%, sodium nitrate 3-10%, potassium permanganate 1-5%, aluminum sulfate 3-6%, sodium chloride 3 -10%, calcium carbonate 5-10%, sodium carbonate 2-8%, manganese dioxide 3-7%, sodium phosphate 3-5%, light magnesium oxide 5-10%.

[0017] The raw materials of the above components are mixed and pulverized according to the percentage weight, and the powder fineness is 20-40 mesh, and then put into the mixer and stirred for 5-10 minutes, and the finished product is inspected and packaged.

[0018] This type A value-added agent is suitable for burning coal with a volatile content of 2.5-3.5%, a calorific value of 3500-4500 kcal / kg, and a sulfur content of 1.2%. The dosage is 1% of that of coal.

Embodiment 2

[0019] Embodiment two: B type value-added agent:

[0020] Oil shale 40-68%, humic acid 11-14%, acidified gangue 2-5%, sodium nitrate 4-10%, potassium permanganate 1-3%, aluminum sulfate 4-5%, sodium chloride 3% -8%, calcium carbonate 6-8%, sodium carbonate 2-5%, manganese dioxide 3-6%, sodium phosphate 3-5%, light magnesium oxide 6-8%.

[0021] The raw materials of the above components are mixed and pulverized with a pulverizer, and the powder fineness is 20-40 mesh, and then put into a mixer and stirred for 5-10 minutes, fully mixed evenly, and then packaged as a finished product.

[0022] This B-type filler is suitable for coal-fired with volatile content of 3.5-4.5%, calorific value of 4500-5500 kcal / kg, and sulfur content of less than 1.5%. The dosage is 1.5% of coal-fired.

Embodiment 3

[0023] Embodiment three: Type C value-added agent:

[0024] Oil shale 40-58%, humic acid 10-12%, acidified coal gangue 4-6%, sodium nitrate 4-8%, potassium permanganate 1-2%, aluminum sulfate 5-6%, calcium carbonate 6- 10%, sodium chloride 4-8%, sodium carbonate 2-6%, manganese dioxide 3-6%, sodium phosphate 4-5%, light magnesium oxide 6-8%.

[0025] The raw materials of the above components are mixed and pulverized by a pulverizer until the fineness of the powder reaches 20-40 meshes, and then put into a mixer and stirred for 5-10 minutes, and the mixture is evenly mixed before being packaged as a finished product.

[0026] This C-type filler is suitable for coal-fired coal with a volatile content of 3-6%, a calorific value of 4000-6000 kcal / kg, and a sulfur content below 1.6%, especially for domestic coal-fired use. 1%, this C-type value-added agent has a wide range of applications.

Abstract

The invention relates to a coal energy-saving clean proliferating agent; by being weighed according to weight percentage of component materials, the proliferating agent comprises the following materials: oil shale, humic acid, acidified coal gangue, sodium nitrate, potassium permanganate, aluminium sulphate, sodium chloride, calcium carbonate, sodium carbonate, manganese dioxide, sodium phosphate and light magnesium oxide; the component materials are mixed and crushed according to percentage weight with powder fineness of 20 meshes to 40 meshes, stirred in a stirrer for 5 to 10 minutes, inspected and packed into finished products. The proliferating agent has rich materials, simple production technique, little investment, fast effect and convenient use; the rate of sulfur fixation and desulfurization is up to 80 percent by inspection of relevant environmental protection and energy-saving departments; the boiler efficiency is improved by 16.8 percent; the carbon content of slag is reduced by 56.7 percent; in addition, by practices, using units prove that the proliferating agent has the advantages and effects of decoking, eliminating smoke and inhibiting corrosion by more than 95 percent.

Description

technical field [0001] The invention relates to a coal-burning additive, in particular to an environmental-friendly, energy-saving, energy-saving, clean and value-added agent for burning coal with oil shale as a carrier for industrial boilers, power plant furnaces, steam furnaces and domestic coal burning. Background technique [0002] Industrial boilers and power plant furnaces are coal-fired furnaces, which also cause air pollution (including SO 2 , CO 2 and smoke, etc.) is one of the main sources of pollution. There are many types of coal-fired additives available in the market, and the single effect is good, but the comprehensive effect is poor. [0003] A kind of " coal additive " disclosed in Chinese patent 95115467.2 is formed by simply mixing potassium permanganate, sodium nitrate (or potassium nitrate), and potassium chloride in an appropriate proportion, and its additive potassium chloride accounts for more than 80%.
