The main principle of this process is tobring flue gas into an intensive contact with calcium hydroxide, open hearth furnace coke, waterand recirculated material in the Turboreactor, which operates as a circulating fluidized bed in themanner of fast fluidization. In 2000 AEE started a development and research project with the aim to simulate the fluiddynamics of the Turboreactor with a commercially used CFD code. Starting with the developmentof the one-phase simulation the existing reactor geometry was optimized concerning the pressureloss. After this step research activities on a two-phase simulation (gas and solid flow) based on theconcept of Euler-Lagrange should help to better understand the mechanism of solid distribution inthe reactor and to calculate the part of the pressure drop of the fluidized bed depending on thesolids. Among other things the recent results of the start-up phase of a TURBOSORP FGD-plant withoptimized reactor design are described in this paper. As a highlight the Turboreactor pressure losswas reduced by about 20 percent, compared to a conventional reactor design. INTRODUCTION Today, the application of dry technologies for the cleaning of flue gases of power stations or wasteincineration plants is considered as the state-of-the-art technology. Due to the use of the fluidizedbed technology and of the recirculation of the partially reacted product it has been possible toeliminate prejudices against this technology which were based u
