Deaerator Erosion – Kansas City Deaerator

Deaerator Case Study:

Deaerator Erosion

Problem:

Deaerator Erosion

A deaerator was thinning out due to erosion underneath the tray stack.

Solution:

A solution would be to distribute the water properly within the tray enclosure. Reduce the steam flow underneath the tray box to an acceptable velocity and/or change operating pressure reduce velocities. Originally the deaerator should have been properly built with adequate area underneath the steam tray box.
