Abstract |
The report gives results of advanced testing from February through November 1976 of 30,000 acfm (10 MW equivalent) lime/limestone wet scrubbers for SO2 and particulate removal at TVA's Shawnee Power Station. Short-term factorial tests (6-8 hours each) with lime, limestone, and limestone/MgO were conducted on both systems to determine SO2 removal as a function of operating parameters. Longer tests (averaging 190 hours each) were conducted on the venturi/spray tower with lime and lime/MgO, both with and without fly ash in the flue gas. On the TCA, longer tests (averaging 180 hours each) were conducted with limestone/MgO, lime, and lime/MgO on flue gas containing fly ash. Adding MgO improved SO2 removal but, in some cases, created a scaling problem. On the venturi/spray tower, particulate mass loading, size distribution, and sulfuric acid mist were measured as a function of operating conditions. Mathematical models fitted to the Shawnee data are presented for predicting SO2 removal as a function of operating parameters. A simplified procedure is presented for calculating gypsum saturation from analytical data. |
