Taking the bubbling tower of the flue gas desulfurization(FGD) system for 600 MW units in Taishan Power Plant and the spray tower of the FGD system for 660 MW units in Shajiao C Power Station for instance,this paper makes a comparative analysis of the bubbling tower and the spray tower in terms of their process,equipment parameters and operation features.

In the recent years,a lot of limestone-gypsum wet method flue gas desulfurization (FGD) facilities have been built up,commissioned or under construction,but over whelming majority of them employ the familiar spraying towers, while the people’s under standing of GT-121(bubbling tower) FGD technology is very limited.

Lime/Lime stone wet flue Gas Desulfurization(FGD) is a common proce ss to control SO2 emission,At the present home 600 MW and above 600 MW unit newly built all use Lime/Lime stone wet FGD process,and absorbed towers in wet desulfu rization process all use sprinkling tower and bubbling tower.

Study on bubble size distribution and local gas holdup in bubble column;

Experimental study on volumetric gas-liquid mass transfer coefficients in slurry bubble columns under elevated pressure and temperature;

Wavelet analysis of turbulent structure at superficial velocity in bubble column;

Experimental study on the distribution of liquid velocity for three-phase bubble columns;

Based on distillation process, the influence of 4A molecular sieve on aqueousalcohol mass transfer was experimentally studied in a three-phase bubble column with30mm in diameter and 600mm in height.
