Embodiment 1

[0019] High-energy coal-fired additives are additives for low (inferior) quality coal, difficult-to-burn coal, non-stained coal, various briquettes, and biomass coal. According to the needs of different users for various fuel coal physical and chemical indicators, one or more fuels can be mixed with additives, and then processed into bulk coal through batching, medium crushing, stirring and other processes; special forming machines can also be used to process into bulk coal according to needs. Burning coals in many shapes.

[0020] The preparation process of the embodiment 1 of the coal-fired additive of the present invention is as follows:

[0021] ① Removal of impurities: The main raw materials in the production process of the coal-fired additives described in the present invention are low-carbon materials, and the leftovers from factories processing other products contain more impurities, which must be removed before use. First, wash with water to remove the surface attach...

Embodiment 9

[0031] In the present embodiment, carry out contrast experiment with two kinds of low-quality coal and the low-quality coal mixed with the additive obtained in the above-mentioned embodiments 1 to 8. In the following examples, the low-quality coal is 10kg, and 0.4wt‰ of combustion accelerant is added according to the total amount of raw coal. Pour it evenly on the raw coal, then fully stir it and dry it in the shade for 2~3 hours, then put it into the furnace and burn it, and the results shown in the table below are obtained.

[0032] Table 2 Combustion of low-quality coal after blending the coal-fired additives prepared in Examples 1-8

[0033]

[0034] To sum up, the coal-fired additive of the present invention can significantly improve the combustion effect of low-quality coal, not only improves the combustion efficiency of the original low-quality coal, but also burns more fully and reduces the cost of coal-fired; With the functions of sulfur fixation, smoke remo...

Abstract

The invention discloses a fuel coal additive. The fuel coal additive comprises the following components in percentage by weight: 1 to 3 percent of sodium hydroxide, 2 to 6 percent of forged coke, 2 to 6 percent of glacial acetic acid, 15 to 25 percent of low-carbon substance, 2 to 6 percent of calcium carbide, 2 to 6 percent of calcium oxide, 2 to 6 percent of ammonium bicarbonate, 2 to 6 percent of waterproof adhesive and the balance of desalted water. The fuel coal additive can be mixed into various fault coals to improve the combustion efficiency of coal and reduce costs of fuel coal, and can also exert the functions of sulfur fixation, smoke removal, odor removal and the like; after the fuel coal additive is combusted, any harmful gas is not discharged; the fuel coal additive can be combusted safely and is high in thermal stability; and low-carbon leftovers in a factory are used as stimulation energy resources, waste is turned into wealth, and production cost is reduced obviously.

Description

technical field [0001] The invention relates to a coal-burning additive, in particular to an efficient and environment-friendly coal-burning additive. Background technique [0002] my country is rich in coal resources, but their quality varies greatly. my country's existing low-quality coal usage has accounted for more than 50% of the total usage. However, low-quality coal has defects such as not easy to burn, low combustion efficiency, and a large amount of toxic and harmful gases after combustion. If it cannot be effectively utilized, it will not only drive up the cost of coal burning but also cause serious pollution to the environment, which is not conducive to environmental protection. The usual method is to mix low-quality coal with high-quality coal. Even if high-quality coal is mixed, it cannot solve the problem of insufficient combustion of low-quality coal; the combustion efficiency of coal can also be improved by improving coal-fired equipment. However, improvin...
