  • steam jet agglomeration part 2 modeling agglomerate growth in a modified steam jet Agglomerator
    Chemical Engineering & Technology, 1999
    Co-Authors: Stefan Hogekamp


    A modified steam-jet Agglomerator employing an adjsutable system of two oblong, slit-shaped steam nozzles is presented. Nozzle position and steam flow towards the powder curtain were optimized by judging the size of the agglomerates produced.

  • development of wet phase transition Agglomerator for multi pollutant synergistic removal

    Abstract This study presents an originally designed device named as wet phase transition Agglomerator (WPTA) based on vapour condensation agglomeration and collection mechanism. This technology has achieved demonstration and commercialization in several industrial/utility boilers. Excellent performances have been validated in fine particles and trace elements synergistic removal, latent heat and water recovery, and sulfuric acid mist control. The vapour condensation produced by the WPTA greatly improve the agglomeration among fine particles and subsequent removal. The removal efficiency of WPTA combined with wet electrostatic precipitator (WESP) for PM1.0 at 600 MW was enhanced by 15%, compared to the operation at WPTA shutdown. About 13.4–15.6 t/h of condensing water was recovered when the designed flue gas temperature was decreased by 1–1.5 °C. Moreover, the WPTA was capable of significantly improving the removing amounts of soluble salts and trace elements from flue gases.

  • Improving the removal of particles and trace elements from coal-fired power plants by combining a wet phase transition Agglomerator with wet electrostatic precipitator

    A novel technology for flue gas pre-treatment in the phase transition process is proposed in this paper to better remove the fine particles and trace elements from coal-fired power plants. Wet removal, Brownian diffusion, diffusiophoresis, thermophoresis and disturbed pipe flow occurring in the phase transition process were taken into consideration during the development of the technology. An item of equipment called a wet phase transition Agglomerator (WPTA) was developed based on the aforementioned technology. The WPTA and the wet electrostatic precipitator (WESP) constituted a wet dust removal system (WDRS), which was used at a 660 MW ultra-supercritical unit in China as a demonstration project. The particles at the inlet and outlet of the WDRS, as well as the wastewater from the system, were sampled to investigate the performance of the WDRS. The results indicate that the WDRS helps to bring about ultra-low emissions of particles from the coal-fired power plant, keeping the level of particle emission below 5 mg/m3under all measurement conditions. It was found that the collection efficiency of the WESP increased significantly with an increasing applied voltage. The performance of the WDRS can be further improved by the WPTA, for the removal efficiency of total suspended particulates at boiler operating loads of 90% and 75% rose 4.01 and 3.17 percentage points, respectively. Moreover, the removal efficiency of PM1increased from 68.67% to 83.61% with the WPTA running at a load of 90%. The TEs removal was also found to be enhanced by the WPTA. The masses of Hg, As and Mn carried by the wastewater per hour with the WPTA running increased 4.2, 2.8 and 1.5 times, respectively, over values when the WPTA was turned off.
