![• A muffle furnace is a furnace
with an externally heated
chamber, the walls of which
radiantly heat the contents of
the chamber, so that the
material being heated has no
contact with the flame.
• It is utilized used as a compact
means of creating extremely
high-temperature atmospheres.
• They are employed to test the
characteristics of materials at
extremely high and accurate
temperatures. [1]

Introduction
Principle
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. 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 material inside the
chamber. [1]
