摘　　要：The emission of fine particulates from the burning of coal can pose a number of problems for human health and the environment.The bag filter is an equipment capable of preventing these particles from reaching the atmosphere.The present work evaluated and proposed improvements based on information received from a process of a company producing vegetable bran and oils,which acts with high emission of particulates.The filter sleeves used were fiberglass fabric with expanded polytetrafluoroethylene membrane.Physical,mechanical and granulometric laboratory analyzes were performed,as well as scanning electron microscopy and dispersive energy spectroscopy for the characterization of the tissue and particulate matter.Based on the results,a new specification of stainless steel cage was proposed for the filter in order to improve the efficiency of retention,as well as to increase the useful life of the filter elements.
