Fugitive emission of dust is common in various chemical, mining and metallurgical process industries and causes severe health problem of the workers in the plant. To control such huge emission generally bag filter system is suitable when temperature is not more than 150 °C. The performance of bag filter depends on the characteristics of dust and its nature of particle settling velocity. In this work an attempt have been made to investigate the effect of particle size distribution and capture velocity of particle on the removal efficiency of the file dusts by using bag filter system. It has been observed that by marinating a capture velocity much higher than terminal settling velocity of the particle resulted in enhanced collection efficiency of the particles and thus minimizes the fugitive emission, which meets the stringent regulations of environmental pollution.
