The Problem in Steam Generation
To generate steam, water is heated in a steam boiler. Oxygen contained in the water can lead to dangerous corrosion. The steam generator feed water therefore has to be degassed, what is done usually by thermal boiling.
The oxygen dissolves in the steam vapours and is continuously blown off via a valve as so-called "Fegedampf" (exhaust vapor) into the free environment. Consequently, there is a loss of steam of 0.2 to 0.5 % of the boiler steam output.
The OXYTRANS Solution in the Steam - Water Degassing Process
With OXYTRANS TR, the degassed O2 content in the vapour phase can be measured in the dome head space of the steam boiler, which is related to the O2 content in the liquid water according to Henry`s law. Within this new measurement process a valve for venting the vapour flow can be precisely controlled. The remaining opening time of the valve is a measure of the steam savings. Steam losses can be reduced by up to 95%.

Parameters: Boiler with 10t/h, assumed steam loss 0.3%, 8760 h/year (365d x24h), ton of steam in Germany 40 €
|Calculated steam loss (0.3%)||263 tons|
|Saved steam loss with Oxytrans TR||250 tons|
|Annual savings (steam x cost of steam/ton)||10.000 €|
|Cost of Investment (Sensor, Shut Off valve, Inst.)||8.000 - 10.000 €|
ROI: less than1 year (much less time for 20t, 30t, 40t steam generator)
