Sectors namely industry, electricity and heat, and also transport account for 84% of global CO 2 emissions [29]. Production of cement refers to the method of energy and resource used, which absorbs almost 12% to 15% of total industrial energy utilization [28]. It also actually reported for 5% to 8% of CO 2 emissions from cement production [26].

Reducing the operating temperature (possible by air dilution upstream from the fan or water spray in the down corner from the preheater section) greatly reduces build-up on kiln ID fans. While temperatures below 500 ºF (260 ºC) are necessary to achieve the reduced build-up, temperatures at or below 392 ºF (200 ºC) increase particle size ...

* India's cement production reached 374.55 million tonnes in FY23, a growth rate of 6.83% year-on-year (yoy). * Indian cement demand is projected to grow by 6-7% in FY25, following a strong 7-8% YoY growth in the last quarter of FY24. Despite a pricing downturn due to increased competition, average cement prices declined by around 1.5% in FY24.

The water quality of Onyi River varied with the sampling periods (Figures 2 and 3). Effluent from cement plant showed variation in terms of pollution load from wet season to dry season taking cue from the production rate of cement. There seemed to be low production turn out in wet season than in the dry season.

Hence, the coal ash content should be maintained reasonably constant preferably to within about +1- 2%. High ash coals, up to 35 or 40% ash content, can be used in cement kilns provided that the ash content is controlled. For coals above about 15% ash content a stockpile-reclaim blending system is usually required.
