Electric Resistance Furnaces
Electric furnaces are the most common type of furnace. They are often used in homes or small businesses. Some electric furnaces have a fan to circulate the heated air.
Electric furnaces provide heat by using electricity to create resistance inside an insulated chamber. The heating element is usually made of metal and is coiled like a spring. It heats up when electricity passes through it, which creates heat that is transferred to the air in the chamber through metal plates called heat exchangers.
History of Electric Resistance Furnaces
History of Electric Resistance Furnace
The electric furnace was invented in 1887 by a German engineer and physicist, Carl Auer von Welsbach. The first electric resistance furnace was used to produce calcium carbide from lime and coke.
Advantages and Disadvantages of Electric resistance furnace
The first electric furnace was invented by a Russian inventor, Elihu Thomson in 1883.
It is also known as the Thomson-Houston Electric Company.
It is considered to be one of the most important inventions of modern times.
The first electric furnace was used for commercial purposes in 1884.
