Problems solved by technology

[0003] The addition of synergists has improved the utilization rate of coal-fired coal. Most of the existing coal-fired synergists use limestone for desulfurization. However, in the high-temperature combustion of coal, the sulfur-fixing efficiency is low, and the sulfur-fixed products are easy to decompose, and the effect is not good. very ideal

Abstract

An yttrium oxide containing environmental-friendly coal-saving synergist is disclosed. The synergist comprises following raw materials by weight: 10-15 parts of yttrium oxide, 2-5 parts of manganese dioxide, 10-15 parts of iron(II) peroxide, 5-10 parts of ferrous oxide, 1-3 parts of sodium carbonate, 1-5 parts of potassium nitrate, 2-5 parts of lignin sulfonate, 5-10 parts of ammonium hydrogen carbonate, 5-10 parts of urea, 1-5 parts of activated carbon, 1-5 parts of diatomite and 2-5 parts of activated aluminium oxide. The synergist has good sulfur fixing effects, a sulfur fixing product is stable and pollutant emission is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of coal additives, and in particular relates to an environment-friendly coal-saving synergist containing yttrium oxide. Background technique [0002] Coal resources occupy an important position in my country's social and economic development, but with the continuous development and utilization of coal resources, many new problems have gradually emerged. Coal resources are non-renewable resources, which means that with the mining and mining of coal, coal resources will decrease day by day. On the other hand, due to the relatively low utilization rate of coal combustion, pollutants are emitted and the environment is damaged. Therefore, how to improve the utilization rate of coal combustion and realize energy saving and emission reduction is a worldwide problem and a topic of common concern all over the world. In recent years, during the rapid development of my country's economy, problems such as low coal ene...
