Abstract:

A power plant has discovered the vaporization in the waterfeeding pump when the deaerator showed normal reading on deaerator level measurement. Focused on the discovery, the researcher found out the existence of distortion on the deaerator level measurement. Discussion and theoretical analysis was carried out to find out the solution to the problem, and to provide reference to the accuracy on the level measurement of the deaerator of similar types.
