CASE STUDY ON CLINKER COOLER POLLUTION CONTROL SYSTEM
Traditionally on clinker cooler application gas conditioner and electrostatic precipitator combination was used world over. However, in certain areas where water is scarce, use of conditioner is a big constraint. Also air pollution control norms are getting stringent day by day which ESP is unable to meet. Similarly efficiency of ESP is not consistent under changing inlet conditions.
RIECO provided answer to the problem at Gulf Cement Company Ras-Al-Khaima UAE by supplying cooler bag filter combination for clinker cooler application. The system is performing satisfactorily meeting stringent emission control norms.
