| Abstract: | On the condition that agitator air lance assemblies are used in the flue gas desulfurization system, the measurements of differential pressure density meters on absorption tower have considerable error. By comparing different setting positions and installation modes with the traditional methods, an improved differential pressure density instrument was presented and installed in the vertical pipe of the circulating pump outlet. The measurement results were excellent in several aspects,giving a high accuracy and reliability. Differential pressure density instruments can be widely used in wet flue gas desulfurization systems. |
