Description

technical field

[0001] The invention relates to a flue gas treatment device. Background technique

[0002] With the continuous development of industry, the various fuels used in industrial production are also increasing, especially the burning of fossil fuels and biomass fuels has become the main source of air pollution today. With the increase of air pollution in recent years, severe smog has appeared in large areas of the country. The emergence of smog not only brings many inconveniences to people's travel, but more seriously damages people's health. For this reason, the state has also formulated many measures for the control and prevention of environmental pollution, and proposed emission standards for substances such as nitrogen oxides, sulfur dioxide, and dust.

[0003] In order to reduce pollution, circulating fluidized bed boiler technology is a high-efficiency, low-pollution and clean combustion technology that has developed rapidly in the past ten years. Internat...
