ABSTRACT:
A method for measuring a pressure drop at a component within a flue gas desulfurization vessel caused by a gas flow includes locating a plurality of taps near the component to be measured in order to receive a portion of the flow. A line leading from the tap is connected to a pressure measuring device in order to measure the pressure at the component based on the flow fed into the tap. After the pressure is measured, the line is disconnected from the pressure device and connected to a cleaning device in order to clean the connecting line and tap. After cleaning the tap, air is blown through the line in order to dry the line for the next measurement. The pressure drop determined is used to calculate the liquid flow passing through the system from pre established relationships.
