4.Dew-condensation and bag-pasting appeared in the filter bag; Because the dust collector operating temperature is lower than dew point temperature, the insulation and sealing measures of the dust collector are not good.

5.Filter bag burns, incineration and other phenomena, which caused by too high operating temperature, high temperature particles entering the dust collector.

6.Large number of holes at the bottom of filter bags are caused by excessive injection pressure. It is recommended to set the ash cleaning pressure as the minimum and the ash cleaning cycle as the longest within the allowable range of differential pressure.
