1) Dust removal efficiency

The dust removal efficiency of the boiler bag filter is usually expressed by the total dust removal efficiency and the graded dust removal efficiency, and the graded dust removal efficiency and total dust removal efficiency of different dust collectors.

(2) Resistance of PL boiler dust collector

The resistance of the PL boiler dust collector indicates how much energy the dust collector consumes. Since the resistance of the dust collector is usually measured under different hot air volume, different flue gas temperature and different air pressure conditions, it is quite convenient to compare. The resistance is converted into the resistance of the boiler under the rated operating conditions of the flue gas volume (that is, the evaporation volume of 1t/h is 3000m3), the flue gas temperature at 20℃, and 101.325kpa.

Ordinary cyclone boiler dust collectors are low in both classification efficiency and total dust removal efficiency. In contrast, the ceramic multi-tube dust collector has a better capture efficiency for dust with a particle size of 5um or more.

 The capture efficiency for dust with a particle size of less than 5m is less than 45%. For wet dust collectors, the graded dust removal efficiency and total dust removal efficiency are both high, and the particle size is less than 5um as well.

 

The lower dust also has the dust removal efficiency. From the point of view of the resistance of the boiler dust collector, the ceramic multi-tube dust collector is larger, and the ordinary cyclone dust collector is similar to the wet dust collector. In addition, ordinary cyclone dust collector without desulfurization performance, the ceramic multi-tube dust collector can desulfurize the flue gas only after adding a desulfurization device.

So in this way, bag type pulse jet is much better, it is convenient to install different kinds of dust collector filter bags according to different working conditions. It can save production cost as well. And it can replace dust collector bags regularly, so it can meet the best filtration efficiency.
