章 638: Upgrade of Blast Furnace & Bessemer Converter Part (2/2)

Vijay nodded in understanding after listening to the problems mentioned by Balachandra. Temperature resistance and fuel efficiency of coal were always a problem even in the 18th and 19th centuries, when the Industrial Revolution was at its peak.

Vijay was curious about the solution obtained by Balachandra because the problem of heat resistance and coal was not simply a bottleneck brought by technical capabilities but due to there being no suitable materials. For instance, the reason for the temperature issue in the blast furnace was because a high-temperature-resistant material had not yet been invented in the Bharatiya Empire. As for the effectiveness of the coal, it is self-explanatory—unless the way coal is processed is changed, the chance of the blast furnace increasing in effectiveness is next to nothing.
