When it comes to heating processes in laboratories, two common types of furnaces are the electric furnace and the electric arc furnace.
4 Key Differences Explained
1. Heating Process
Electric Furnace: An electric furnace, particularly an induction electric furnace, generates heat through electromagnetic induction.
Electric Arc Furnace: An electric arc furnace generates heat by striking an electric arc between two electrodes.
2. Material Handling
Electric Furnace: Induction electric furnaces, like medium frequency induction furnaces, are often used for melting scrap steel.
Electric Arc Furnace: Electric arc furnaces can handle a wide variety of materials, as the material is directly exposed to the electric arc.
3. Environmental Impact
Electric Furnace: Induction electric furnaces are more environmentally friendly compared to electric arc furnaces.
Electric Arc Furnace: Electric arc furnaces have a larger environmental impact due to the production of exhaust gas, waste residue, and noise, as well as their higher energy consumption.
4. Efficiency and Speed
Electric Furnace: Electric furnaces offer high heating speed and thermal efficiency.
Electric Arc Furnace: Electric arc furnaces have lower heating speed and lower thermal efficiency compared to electric furnaces.
