ISON ENDO GAS GENERATOR
EXO-GAS (LEAN RATIO):

These atmospheres ranging from 90 % to 98 5 of perfect combustion have the following composition :

CO2 : 11 to 13 %
CO : 0.5 to 1.5 %
H2 : 0.5 to 2 %
N2 : Balance
These are normally used for bright annealing of copper , scale-free annealing of brass and similar operation on non-ferrous metals.


EXO-GAS (RICH RATIO):

The protective gas rich in CO and H2 is known as rich exo gas and is generated within 55 % to 90 % of perfect combustion , the gas composition will be:

CO2 : 5 to 6 %
CO : 10 to 12 %
H2 : 11 to 13 %
N2 : Balance

The composition of atmosphere gas depends on composition of fuel also.
The presence of reducing constituents CO & H2 will effectively prevent the oxidation of many metals. These atmospheres are , therefore, ‘Reducing’. However, since appreciable amount of CO2 is present, the atmosphere becomes decarburizing in character.
