The development of a powerful new Bell less top (BLT) charging system, together with operation through various electric and electronic control solutions has gained in function of the numerous tops in operation and has developed quite sophisticated computer backed up systems. It offers flexible distribution, good sealing, capital saving, easy maintenance, high efficiency etc. In this report, theoretical studies are performed for the design and working of the system, and thus the possible types of charging accomplished with the BLT system by way of imparting proper degrees of freedom to the charge distributing chute. The mechanism of operation of the chute through the transmission of power through different gears and shafts assembly is studied in good detail. It is observed that in modes of operation of the chute when only tilting motion is required, certain degree of rotation and vice versa is taking place which is not desirable and hence is to be prevented. We laid a major emphasis on the study and analysis of heat flow in the transmission gear box of Bell Less Top charging system. In this project analysis of heat load will be studied and adequate cooling system to be incorporated for proper cooling and to increase the life of gear box. The aim of this project is to study the cooling effect with only nitrogen as cooling media,and arrest of chokage of surpentine tubes by replacing close loop water circuit in Blast Furnace number -4. Analysis has been done by using Ansys Fluent analysis software and Solid works and Auto CAD modelling software.
