ElectroStatic Precipitators (ESP) are widely used in coal fired power plants for control of particulate matter and other toxic gases. Traditionally, ESP’s used metal plates as collecting surfaces for capture of particles in flue gas. However, back corona and re-entrainment of particles into flue gases hinder with the performance of ESP in collection of fine particulate matter (PM2.5). Metal plate ESP’s also suffer from problems due to corrosion. Researchers at Ohio University developed a patented wet membrane based ESP to overcomes these difficulties. Wet membrane based ESP replaces the metal collecting surfaces with woven fabrics. Omnisil 1000, a silica fabric (98.5% silica), is found to be suitable for this application. The replacement of metal collecting plates with fabric requires application of tensile loads on the fabric during operation of ESP. A study of tensile and creep behavior is presented. A test facility for uniaxial tension and creep testing of Omnisil fabric is developed. The uniaxial tensile behavior of the fabric is typical to plain woven fabrics and the failure strength bears a linear relation to fabric width. The creep elongation of the fabric is negligible in the experimental conditions.
