1 Exo Gas Generators EXO- Gas Generators produces protective atmosphere for Heat Treatment Furnace. Lean Exo- Gas or Rich- Gas is produced simply by charging the air to fuel ratio in burner. Lean Exo Gas Principle Lean Exo-Gas is produced by burning of fuels at slightly lower Sub-Stoichiometric Combustion Air to fuel ration. This Exo Gas is lean in CO + H2 Content. Lean Exo- Gas Generators are Suitable for non ferrous metals heat treatment Rich Exo Gas Principle Rich Exo-Gas is produced by burning of fuels at slightly high Sub-Stoichiometric Combustion Air to fuel ration. This Exo Gas is Rich in CO + H2 Content. Rich Exo- Gas Generators are used for heat treatment of steel and also brazing and annealing Application By providing a Refrigerated dryer after Gas Generators dew point of (+) 5 C is achieved. For (-)60 C dew point, a Molecular Sieves dryer provided
2 These Gas Generators are fitted with a specially designed Swirl flame burner which give soot combustion and oxygen Free Exo-Gas even under sub-stoichiometric condition. Burner is ignited by spark plug and flame is continuously monitored by UV - Flame scanner. Safety Interlock Fuel supply to burner stops automatically and Gas Generators Shuts down safety givening audio-visual alarm due to any problem like low combustion air pressure, flame failure, low water, or low fuel Pressure. Fuel The following fuels can be used in these Exo Gas Generators. Natural Gas LPG PROPANE GAS Capacity 10 Nm3/hr to 5000 Nm3/hr (-) 5 C to (-) 60 C

5 Endo- Gas Generators Endo Gas (endothermic gas) Generators Produce Endothermic Gas (mixer or CO, CO 2, N 2 and H 2 ) by reaction of air and fuel nickel Catalysts at 1050 C temperature. Endothermic Gas Generators Principle Endothermic Process requires external heat which is provided by electrical Heater of fuel burning around the retort. Retort is made of heat résistance alloy suitable for 1050 C temperature. Due to Cracking of fuel, some Carbon Deposit on Catalysts, which is burnt off every 15 days running by regeneration process which regains Catalyst Activity? Fuel The following fuels can be used in these Endothermic Gas Generators. Natural Gas LPG PROPANE GAS Applications: The Endo Gas Generators are used following Furnaces Gas Carburizing Carbon restoration in Steel Carbo-nitriding Hardening / Annealing High Temperature Brazing Sintering Reduction of metal oxide Capacity 10 Nm3/hr to 100 Nm3/hr
