Muffle Furnace:

The working principle of a lab muffle furnace is to heat the air in the chamber by heating the Nichrome (nickel-chromium) wires which are generally referred to as electrically operated heating elements. The Control of furnace temperature majorly depends on the efficiency of electronic controller unit and best results can only be obtained from PID controlled units, PID stands for proportional integral derivative controller. The laboratory muffle furnaces generally do not have sophisticated cooling system. Most of the time a simple fan based exhaust system is installed and cooling is performed by this simple fan system supported by a chimney. The main utility of this furnace exhaust system is to take out the toxic gases from the inner chamber which comes out during heating of the testing materiel / specimen inside the chamber. Hence the chamber gets sanitised of any toxic gases which may have evolved during the heating of materiel inside the lab muffle furnace.
