Abstract
A new design of a scrubber has been developed and used in a deaerator. Deaeration of feed water in the boiler system is an essential process in industry today. Any facilities operating with steam have at least one deaerator to remove dissolved oxygen from the feed water. For an efficient removal process, the feed water has to be heated up to the saturation temperature at the pressure in the outlet section of scrubber. Numerical simulations were conducted for various designs of a scrubber with data used in the power plant industry in Korea and an efficient design was drawn from the numerical results. Experiments were conducted with new design of the scrubber for operating conditions similar to those in a power plant. The experimental results showed an excellent deaerator performance, satisfying the standard requirement of dissolved oxygen level of 5–7 ppb in industry.
