Investigation the Status Monitoring, Maintenance and Problems of Electrostatic Precipitation in Cement Factories in Iran

In cement production factories, dust is produced due to corrosion, grinding, replacement, and baking materials in the furnace. Electrostatic precipitation is one of the most widely applied technologies for the removal of hazardous particles from cement factories. In this study, some questionnaires were designed, by attention with several studies and its standards and catalogs of production for this equipment. Then, the questionnaires were distributed in the factories under study and the following information was obtained. The Excel software was used for analyzing the data. The data were analyzed employing t-test and Chi-square. The results of the study showed that the maximum removal efficiency of particles had been obtained to 99.98% by to ESP system. Also, it was observed that the rising CO gas was the most effective factor in the shutdown of ESP systems. The results showed that the maximum rate of monitoring and maintenance in control systems was in the ESP for annual monitoring (94%). The results of the study showed that because of inaccuracy and indifference in daily, weekly and monthly monitoring, problems in the control systems daily are more; and the solutions such as designing monitoring programs, worker training human resources, renewal and improvement in technology can play a fundamental role in alleviating these problems.
