1. How it will ensured that the quantum of the Coke consumption reduction is attributed to the Bell Less Top only? It is evident to any person having a small idea on the Blast Furnace that the coke consumption varies sue to several factors like quality of Sinter/Pellet, Ore quality, etc. Therefore, how can the boundary conditions be fixed and be ensured that the emission reductions are solely attributed to the Bell Less Top charging system.
2. The reduction in the Coke consumption can also be attributed to the higher grade of Coke charged in the BF due to higher grade of Coal usage in the Coke Oven Plant and also some process modifications in the Coke Oven Plant.
3. The quantity of Hot Metal at the baseline scenario cannot be obtained from the design basis report. The same is based on a lot of assumptions and fixed parameters that was considered during the design of the BF. However, the same is never followed in the actual processes and therefore consideration of the design basis figure is not possible. 
4. It is mentioned that the use of Bell Less Top is a first of its kind endeavor.However, please have a look at the website of Paul Wurth and other public sources, where in there are a lot of Blast Furnaces operating with a Bell Less Top. TATA Steel, Jaiswal Neco etc are a few examples. Further, it is to be further explained that how a Blast Furnace in the eastern part of the India is different from that of a furnace in western part.
5. The project proponent has mentioned that the project will face barriers in terms of availability of technology supplier. Please be informed that there are many established supplier of the same in the country.
6. It is also to be noted that increase in Hot Blast Temp may result in lowering of the Coke consumption in the Blast Furnace. The project proponent is to clarify that how the varying temperature of th Hot Blast is accounted in the computation of the reduction of the Coke. 
7. It is to be further noted that the use of PCI and the quality of the same is also a determining factor for the reduction in the coke, which again has not been considered.
