OXYSTEAM - Steam boiler water degassing

 To generate steam, water is heated in a steam boiler. The oxygen contained in the water can lead to dangerous corrosion. Therefore, the water must be thermally degassed. The oxygen dissolves in the steam vapors and is released into the environment via a valve as so-called "sweep steam." This results in a steam loss of 0.2 to 0.5% of the boiler's steam output. With OXYTRANS TR, the degassed O₂ content in the steam gas phase in the boiler's dome can be measured, and the valve for releasing the swept steam can be precisely controlled accordingly. The resulting remaining valve opening time is a measure of the steam savings. Steam losses can be reduced by up to 95%. For a boiler with a capacity of 10 t/h and an assumed steam loss of 0.3%, this results in a steam loss of 263 t per year (365 days x 24 h = 8,760 h). This will save 250 tons. Assuming a price of €40 per ton of steam, the savings amount to €10,000, with a sustainable return on investment of less than 6 months.
