Coal-saving combustion improver improving coal combustion efficiency

Abstract

The invention discloses a coal-saving combustion improver improving the coal combustion efficiency. The coal-saving combustion improver is prepared from an oxygen producer, a curing agent, a catalystand a main raw material. The coal-saving combustion improver is prepared from the components in percentage by weight: the oxygen producer: 10% of sodium chloride, the curing agent: 10% of epoxy resin,the catalyst: 5% of calcium carbonate, the main raw material: 60% of mineral powder, a synergist: 5% of a fuel gas synergist, and an enhancer: 10% of stearic acid. The raw materials are placed into amixer to be mixed and stirred, and the mixed material which is blended uniformly is ground to be powdery by using a grinder. The coal-saving combustion improver is formed through matching of variouskinds of raw materials, the raw materials are mixed at different ratios, 10% of coal can be saved by adding 1% of coal-saving combustion improver, the economic cost is reduced, the coal sources are saved, and the utilization efficiency of the coal is improved. The raw materials are mixed more sufficiently through forward and reverse rotation of stirring blades and design of multiple grinding procedures, the homogenization and the pulverization of the mixed material are ensured, and accordingly the good combustion effect is achieved.

Description

technical field [0001] The invention relates to the field of coal-fired thermal power plants, in particular to a coal-saving combustion aid for improving coal-burning efficiency. Background technique [0002] Coal is a combustible black or brownish-black sedimentary rock that usually occurs in rocky formations or veins called coal beds or seams because of subsequent exposure to elevated temperatures and pressures in a harder form Coal can be considered as a metamorphic rock, such as anthracite. Coal is mainly composed of carbon, together with varying amounts of other elements, mainly hydrogen, sulfur, oxygen and nitrogen. With the rapid development of society, coal mines have become a development However, due to the long-term use of coal, coal resources are greatly reduced, and the combustion efficiency of coal is low, which reduces the utilization rate of coal and greatly wastes resources. Therefore, those skilled in the art provide a coal-saving combustion accelerant for ...

[0002] Coal is a combustible black or brownish-black sedimentary rock that usually occurs in rocky formations or veins called coal beds or seams, and because of later exposure to elevated temperatures and pressures, the harder form Coal can be considered as a metamorphic rock, such as anthracite. Coal is mainly composed of carbon, together with varying amounts of other elements, mainly hydrogen, sulfur, oxygen and nitrogen. However, due to the long-term use of coal, coal resources are greatly reduced, and the combustion efficiency of coal is low, which reduces the utilization rate of coal and greatly wastes resources.
