Stepping up to new industrial solutions for Power industry<\/strong><\/p>

Introduction<\/strong>:<\/p>

Clair supplied a hybrid filter to a reputed Cement manufacturer based in Andhra Pradesh. The unit had its own captive power plant which was in requirement to control emissions from its Coal firedboiler exhaust gases. Clair proposed to install a hybrid filter with 1st<\/sup> and 2nd<\/sup> field as an ESP and 3rd<\/sup> and 4th<\/sup> field is a bag filter.<\/p>

The dust laden gases first enter in to the \u2018ESP\u2019 field. The dust particles are \u2018electro-statically charged\u2019 in this field section and then move to the \u2018bag house\u2019 section. Majority of the dust also gets collected in the 1st<\/sup> field. The \u2018charged\u2019 dust particles moves over to the bag filter fabric and form a \u2018porous cake\u2019 over the surface and are filtered out from the gas stream. The dust layer forms a porous cake mainly due to the charged dust particles. Such \u2018porosity\u2019 of the dust cake layer helps to achieve a lower \u2018diff. pressure\u2019 and this also prevents any major re-entrainment during pulsing \/ bag cleaning operation.\u00a0\u00a0<\/p>

The order was won in 2012 and system was commissioned in 2013. The specifications of the hybrid filter are mentioned in Table 1.<\/p>

Observations:<\/strong><\/p>

Clair successfully implemented and commissioned the installation to achieve the emission of \u2264 20 mg\/Nm3<\/sup>with a pressure drop of 120 mmWC. Since it\u2019s commissioning it is operating successfully as per the designed emission norms.<\/p>
