Blast Furnace Design
This diagram of blast furnaces at the French naval gun foundry at Ruelle shows the
capital plant that began to transform the ferrous metallurgical industries of Britain
and France towards the end of the eighteenth century. These twin furnaces were ten
meters high and could melt enough iron to cast several cannon at once. Note the
power-driven bellows which intensified the fire by supplying extra oxygen to the
flame.
