Features of dust filter bags

1, the discharge concentration is not affected by the nature of dust specific resistance, concentration, particle size, etc. Boiler load change, flue gas volume fluctuation has little effect on the discharge concentration of bag filter outlet.
2、In dry and semi-dry desulfurization system, it has the effect of further reducing the SO2 contained in flue gas.

3、Usually, the bag filter is divided into chambers, and there is a margin in the design. Dust collector chamber can be rotated for maintenance without affecting the operation of boiler. Therefore, the impact on boiler equipment availability is close to zero.
4、Bag filter is more useful for capturing fine dust, it removes more rare metal particles contained in fly ash than electric dust, and it is useful for removing PM10, PM2.5 fine dust, which can reduce the damage to the health of the surrounding people.
5、Bag filter construction and protection are relatively simple.
6, as the key issue of bag filter - filter material, now there is also a breakthrough, the service life is usually more than 2 years, in fact, there are up to 4-6 years of actual performance.
7, the discharge of dust concentration is low, usually less than 50mg / Nm3, or even less than 20mg / Nm3. for low sulfur coal and high ash coal, with electric dust collector to reach such a low concentration is not easy, or to add more funding (i.e. the more conventional 3 electric field to expand to 4-6 electric field).
