Foreword
Cement industry in India has been identified as one of the major air polluting industries for which the Central Pollution Control Board evolved emission regulations for different plant production capacities. The emission standards are applicable for all sections of production in cement plant, such as raw mill, kiln, coal mill, clinker cooler, cement mill etc. In order to combat emission from these sources and comply with the standards, cement industries are installing different types of pollution control devices. In this context, it was felt necessary to undertake a study on the "cost benefit analysis of various dust control equipment in cement industry" to establish the economic viability of various dust collectors used in cement plants of varying capacities. The study was carried out by the National Council for Cement and Building Materials (NCB), Ballabhgarh in association with the Central Board. Findings of the study form the basis of this report. Dust collectors for different.sections have been recommended depending on the requirrnents of the emission regulation and their pay-back periods are also brought out in the report.
