Several important factors affecting the service life of high temperature filter bags:
1. Deashing method (reverse blowing type has longer life than pulse type)
2. Filtering wind speed (the higher the filtering wind speed, the shorter the life of the filter bag)
3. The structure and design of the dust collector include the distance between the filter bag and the wallboard, the interval between the filter bag and the filter bag, the position of the air inlet and outlet, and the installation of the deflector.
4. The quality of coal and the nature of the flue gas produced by the boiler contains water, sulfur oxides, and nitrogen oxides. The higher the oxygen content, the more significant the impact on the life of the bag)
5. The temperature of the flue gas (the flue gas temperature exceeds 170℃, which has a significant impact on the life of the bag. The general principle is that the higher the temperature, the shorter the life, because the flue temperature accelerates the reaction ability of chemical substances)
6. Dew point temperature and critical temperature (The ideal state is that the flue gas temperature remains uniform and less fluctuating within the 4-year life span. Electronic control measures must be taken to prevent the flue gas with too low or too high temperature from contacting the cloth bag.< br>
