Several important factors affecting the service life of PPS filter bags in power plants

<p>Several important factors affecting the service life of PPS filter bags in power plants:</p><p>&nbsp;</p><p>1. Deashing method (reverse blowing type has a longer life than pulse type)</p><p><br></p><p>2. Filtering wind speed (the higher the filtering wind speed, the shorter the life of the filter bag)</p><p><br></p><p>3. The structure and design of the dust collector include the distance between the filter bag and the wallboard, and the distance between the <a href="https://www.lyfilter.com/products" rel="noopener noreferrer" target="_blank">filter </a>bag and the filter bag</p><p><br></p><p>The interval between the air inlet and outlet, the position of the air inlet and outlet, the installation of the deflector, etc.</p><p><br></p><p>4. The quality of coal and the nature of the flue gas produced by the boiler contains water, sulfur oxides, nitrogen oxides, and oxygen content. The higher the bag life, the more significant the impact)</p><p><br></p><p>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)</p><p>&nbsp;</p><p>6. Dew point temperature and critical temperature (the ideal state is to maintain the flue gas temperature within 4 years of life</p><p><br></p><p>Consistent equilibrium and less volatility. There must be electronic control measures to prevent the flue gas of too low or too high temperature from contacting the cloth bag.</p>
