Endo And Exo Gas Generators

We are the leading manufacturer of Endo and Exo Gas Generators and our product are made of good quality.

The fundamental importance of carbon in determining the mechanical properties of steel, special attention has been devoted to those controlled atmosphere processes that are require to control carbon exchange between the furnace atmosphere and work being treated.

The endothermic gas yields a potential between 0.7 to 0.9 which corresponds to the surface carbon content aimed at in the majority of processes. Endothermic atmospheres are used principally in the heat treatment of carbon steels and may be slightly carburizing to low carbon steels. Endothermic gas is produced by the reaction of an air-gas mixture ranging from 25 to 40% of perfect combustion. It is necessary to supply external heat in the endothermic reaction. The process is based on single catalytic cracking of LPG or natural gas with accompanying admission of air at such a rate that the product gas after cracking contains only CO, H2, N2 and traces of CO2 and moisture.

Our endothermic gas generator consist of a mixer unit, cracking retort, gas cooler and control panel. All equipments are accommodated in a single compact unit. The reaction takes place in presence of high activity catalyst at a working temperature around 1050oC. Heating of the retort is affected electrically by heating elements around the retort.
Exo-gas (lean ratio) : These atmospheres ranging from 90 % to 98 5 of perfect combustion have the following composition :
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:
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. However, with the presence of CO2, the atmosphere becomes de-carburizing in character.

Therefore we offer following type of exo-gas generator :
Raw Exo - Gas Type : Where the products of combustion are directly used as. Protective gas.
Partially Dry Exo - Gas Type : Certain applications require only partial removal of moisture to prevent oxidation and de-carburization. In these, the gas are passed through a refrigeration unit to reduce the dew point to around plus 5oC.
Perfectly Dry Exo - Gas Type : Wherever materials call for moisture free gas generator is followed by a refrigeration unit and a packaged drier. Here the dew point of the product gas is reduced to around minus 40oC.

Fuel : Natural Gas, LPG, Kerosene, Diesel.
Capacities : 10 nm3/hr to 1000 nm3/hr in various standard sizes.
