Exothermic Gas Generator,
Exothermic DX Gas Generator for Heat Treatment Fastener Production
Exothermic generators are designed to produce cover gases for a variety of applications from use as a
non-oxidizing atmosphere in the heat treating of bright metals, such as aluminum and copper, to providing a carburizing atmosphere for some metals to simply providing an inert and explosion-proof environment in which to mix chemicals, formulate flammable recipes or prevent combustion. These cover gases are produced from the combustion of hydrocarbon fuels. Although propane and natural gas are the most commonly used, virtually any combustible fuel, such as MAP gas or even liquid fuels, such as kerosene or fuel oil, can be used.
Exothermic generators, built by Thermal Dynamix, are compact; water-cooled units for either rich or lean atmospheres. Although natural gas and propane are normally used as fuel other materials such as, MAP gas, methane and even alcohol can be used.
The exothermic generator is essentially a very tightly constructed and controlled combustion chamber into which
a precisely measured and controlled mixture of air and fuel are introduced and ignited. The mixture burns at temperatures from 1,900F to 2,300F.
There are actually two types of exothermic gas generators; one to produce a lean exo-gas comprised largely of nitrogen and carbon dioxide (with very little hydrogen) and a different type to produce a rich exo-gas containing somewhat less nitrogen and carbon dioxide and substantially more carbon monoxide and a larger hydrogen component.
Generally speaking the lean exo generator produces an output gas composition of approximately:
10.5% Carbon Dioxide
1.5% Carbon Monoxide
A rich exo generator produces an output gas composition of approximately:
5.0% Carbon Dioxide
10.5% Carbon Monoxide
The difference in the two types is that the firing of a very rich fuel mixture, in the rich generator, requires the
a catalyst bed to ensure the complete cracking of the products of combustion.
Upon completion of the combustion process, the gas, now depleted of any oxygen, is cooled to about 120 F and sent to its intended use. Sometimes the gas is dried to a very low dew point and occasionally it is compressed
but often it is used as it is produced without further finishing.
Normally, the final dew point of the process gas is approximately 10 F above the cooling water temperature (i.e. 50 F water = 60 F dew point). However, with the addition of refrigerated gas dryers, dew points as low as -40 F are possible. Thermal Dynamix exothermic generators are equipped with variable speed pumps enabling the generator output to be varied in response to demand. Separate electric-ignition pilot systems are provided for push button ease of start up. The combustion chambers are fabricated from rugged, light weight, high performance, ceramic material and are designed to be easily serviced. Control and programming is by touch screen which enables clear and unambigous read-outs of operating parameters.
