對袋式除塵器來說，使用溫度與除塵效率關系并不明顯，這一點不同于電除塵，對電除塵器來說，溫度的變化會影響到粉塵的比電阻等影響除塵效率。
For bag filter, the relationship between the service temperature and the efficiency of dust removal is not obvious, which is different from the electrostatic precipitator. For the electrostatic precipitator, the change of temperature will affect the specific resistance of dust and so on.
入口含塵濃度(g/m³)：即入口粉塵濃度，這是由揚塵點的工藝所決定的，在設計或選擇袋式除塵器時，它是僅次于處理風量的又一個重要因素。
The entrance of dust concentration (g/m: entrance dust concentration fand), which is decided by the process of dust, in the design or selection of bag type dust collector, it is also an important factor behind the air quantity.
以g/m3或g/Nm3來表示。對于袋式除塵器來說，入口含塵濃度將直接影響下列因素：壓力損失和清灰周期。入口濃度增大，同一過濾面積上積灰速度快，壓力損失隨之增加，結果是不得不增加清灰次數。
It is represented by g/m3 or g/Nm3. For the bag type dust collector, the dust concentration at the entrance will directly affect the following factors: the pressure loss and the ash clearing period. With the increase of the inlet concentration, the speed of ash accumulation on the same filter area is fast, and the pressure loss increases. The result is that the number of ash clearing times has to be increased.
濾袋和箱體的磨損。在粉塵具有強磨蝕性的情況下，其磨損量可以認為與含塵濃度成正比。預收塵有無必要。預收塵就是在袋式除塵器入口處前再增加一級除塵設備，也稱前級除塵。排灰裝置的排灰能力。
The wear of the filter bag and the box. In the case of strong abrasiveness, the amount of wear and tear can be considered to be proportional to the dust concentration. There is no need to pre collecting. The advance is in the dust bag dust collector at the entrance before the increased level of dust removal equipment, also known as the dust before. Ash discharging capacity of ash discharging device.
