Pushing ESP boundaries<\/strong><\/p>

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

We have had an opportunity to work with another reputed cement manufacturer located in Rajasthan. The clinker cooler gases were led into an ESP, which was originally designed for achieving an emission of \u2264 50 mg\/Nm3<\/sup>. The client had to meet the recent norms of \u2264 30 mg\/Nm3<\/sup> emission from the ESP. The client was also proposing to install a WHRS system after the clinker cooler, where the gases from clinker exhaust will be led into the WHRS and the gases from the WHRS outlet will be taken into the ESP for control of particulate matter. The existing ESP was designed for a volume of 4,87,200 m3<\/sup>\/h at an inlet temperature of 280 0<\/sup>C. The existing ESP is a 3 field ESP, with 14.5 m collecting electrode height and a gas velocity of 0.69 m\/s.<\/p>

The ESP was not performing as per the designed emission norms due to some internal problems. Clair was handed with the task to achieve an emission of \u2264 30 mg\/Nm3<\/sup> for the conditions specified in Table 1 with the installation of WHRS.<\/p>
