Abstract

In the fuel shed of a biomass SRF power plant generates a large amount of high concentration of scattered dust, which can lead to health problems, safety and facility accidents for field workers. This study was conducted to develop a collection technology suitable for the characteristics of biomass scattering dust. A PTFE membrane with a pore size of 0.05 to 10 ㎛ was developed and laminated on a felt to make a filter bag. PTFE membrane filter bags are used in dust collection systems that require durability, high temperature and chemical resistance to efficiently remove fine dust and maintain high-efficiency performance for a long time. The PTFE membrane filter bag is a surface filtration method that prevents fine dust from penetrating the inside of the filter material, thus maintaining filtration efficiency and a long service life. It has efficiency of collecting more than 99.94 % needle-shaped scattering dust.
