Improvement in Gas-Furnaces and Forges.
Patent for "an apparatus in which the gases from one or more forges, instead of passing off unconsumed into the atmosphere, enter a furnace and are burnt therein, thereby furnishing heat for the generation of steam in a boiler connected with said furnace, which steam is used to drive a fan that impels a blast into each forge, and is also used to propel an engine that operates a hammer, the exhaust from the engine being conducted to the tuyeres of the forges through pipes in which are placed red-hot iron plates, which decompose the steam, taking up the oxygen, and liberating the hydrogen which is burnt in the forges."
