When it comes to the temperature a furnace can reach, it varies significantly depending on the type of furnace and the heating elements used. Understanding these differences can help you choose the right furnace for your needs.
How hot does a furnace get in Celsius? (4 Types Explained)
1. Tube Furnaces
Tube furnaces can reach a wide range of temperatures. For instance, Carbolite Gero tube furnaces have maximum operating temperatures ranging from 1100°C to 2600°C.
2. Gas Furnaces
Gas furnaces offer another way to achieve high temperatures. An ordinary gas furnace using illuminating gas made from coal and air at 2 or 3 lb. pressure can reach about 1400°C.
When burning natural gas, temperatures can be 100°C or 200°C higher.
With higher air pressures and illuminating gas, temperatures as high as 1650°C can be obtained.
In the case of natural gas, temperatures can reach as high as 1800°C.
By recuperating waste heat, preheating gases, or adding oxygen, temperatures over 2000°C have been maintained in some cases.
3. Muffle Furnaces
Muffle furnaces also have different maximum temperature ranges depending on the type of heating elements used.
Furnaces with metallic wire heating elements can reach temperatures ranging from 1000°C to 1200°C.
Molybdenum disilicide heating elements, on the other hand, are able to reach temperatures as high as 1800°C.
In general, muffle furnaces have maximum temperatures ranging from below 1000°C to above 2000°C.
4. Choosing the Right Furnace
It is recommended to choose a furnace with a temperature range that exceeds your application's required temperature to provide flexibility for future applications.
It is also important to consider machine safety features when choosing a furnace, such as automatic shut-off, over-temperature protection, forced cooling, and self-diagnostic functions.
