Description Advantages This generator was developed to enable the heat-treater to produce alternative(y endothermic or Adjustment exothermic atmospheres, as required, of stable composition and without formation of sool. - Equally well-suited for production of endothermic and exothermic atmospheresThese atmospheres are made by reaction of propane or methane (natural gas) with air. Wh en - Quick change of atmosphere possibleendogas is required, this reaction takes place in a retort heated to about 1000°C, forming a - Wide range of adjustment for varying themixture of carburising, decarburising and inert gasses in concentrations as shown in the table gas compositionbelow (approximate values): - Instant change of gas volume possible CO CO2 CH4 H2 H20 Reliability Raw Air:Gas - Constant composition of gas for every % % % % % N2 gas ratio air:gas ratio by volume by volume by volume byvolume by volume - Constant dew point from non-changing Propane Methane - 8:1 -2.5:1 23:25 19:21 0.3 to 0.4 0.2 to 0.3 0.1 to 0.5 O.l to 0.5 33 39 0.6 to 0.8 0.6 to 0.8 Balance Balance raw gas Purity reaction - No soot formation with steel + - - + + (-)* - - 0 - Moisture removal to desired values possible - Remaining moisture adjustable * at very high temperatures + = carburising - = decarburising 0= inert OperationWhen exothermic gas has to be produced the air:gas ratio is changed to 12: 1 or higher. No - Very simple operationheating of the retorts is now necessary as the reaction is self-sustaining and energy-releasing. The - Ail switches, knobs, buttons and controlscomposition of exothermic atmospheres depends largely on air:gas ratio selected.
