The smoke emission of secondary stage electrostatic precipitator(EP) in RCFB desulfuration system had surpassed the set standard

the RCFB desulfuration system of 2×300 MW units in extension project of Guangzhou Hengyun Power Plant had to be replaced by using bag dust collector with high concentration. After putting into operation

the concentration of smoke emission has been reduced to lower than 50 mg/m3(standard state)

the control of bag dust collector to be simple

and its operation to be stable and reliable. The filtering bags have good performance of anti-corrosion and moisture-resistance

and boasting long service life.
