Embodiment SA1

[0052] The liquid A (100 parts by weight) was mixed with coal at a ratio of 0.03 weight % for combustion treatment. The specific conditions and results are shown in Table 1.

Embodiment SA2

[0054] The liquid A (100 parts by weight) was mixed with coal at a ratio of 0.2 weight percent for combustion treatment. The specific conditions and results are shown in Table 1.

Embodiment SA3

[0056] Adding 18 parts by weight of titanium dioxide to liquid A (100 parts by weight) was used as a coal-burning additive, and mixed with coal in a proportion of 1% by weight for combustion treatment. The specific conditions and results are shown in Table 1.

Abstract

The invention discloses a coal additive and application thereof. The coal additive comprises waste polyester depolymerization reaction liquid and / or waste obtained after fractionation of the depolymerization reaction liquid and further comprises an optional catalyst and an optional oxygen producer. By the coal additive, waste polyester depolymerization reaction liquid and / or waste obtained after fractionation of the depolymerization reaction liquid can be applied to coal combustion, and a great combustion supporting effect is achieved.

Description

technical field [0001] The disclosure relates to a coal-burning additive and its application, which is suitable for various industrial boilers, power plants, cement plants, brick kiln factories and civil scattered-fired coal. Background technique [0002] Coal is mainly used for thermal power, cement, metallurgy and chemical industry, etc. With the process of industrialization, people's demand for coal continues to increase, but coal is a non-renewable resource and the combustion process has a great impact on the environment. Therefore, improving the combustion efficiency of coal has both economic and social benefits. [0003] Coal-burning combustion-supporting agent is a kind of combustion-supporting additive for the coal combustion process, which has the effect of saving coal. There are many reports on this aspect, such as the earlier CN88105782.7 in China discloses a coal combustion aid, which is mainly composed of nitrates, iron oxides, manganese compounds, chlorine com...
