  • Energy recovery from sewage sludge by means of Fluidised Bed gasification
    Waste Management, 2008
    Co-Authors: Bodo Groß, Christian Eder, Peter Grziwa, Juri Horst, Klaus Kimmerle
    Abstract:

    Because of its potential harmful impact on the environment, disposal of sewage sludge is becoming a major problem all over the world. Today the available disposal measures are at the crossroads. One alternative would be to continue its usage as fertiliser or to abandon it. Due to the discussions about soil contamination caused by sewage sludge, some countries have already prohibited its application in agriculture. In these countries, thermal treatment is now presenting the most common alternative. This report describes two suitable methods to directly convert sewage sludge into useful energy on-site at the wastewater treatment plant. Both processes consist mainly of four devices: dewatering and drying of the sewage sludge, gasification by means of Fluidised Bed Technology (followed by a gas cleaning step) and production of useful energy via CHP units as the final step. The process descriBed first (ETVS-Process) is using a high pressure technique for the initial dewatering and a Fluidised Bed Technology utilising waste heat from the overall process for drying. In the second process (NTVS-Process) in addition to the waste heat, solar radiation is utilised. The subsequent measures - gasification, gas cleaning and electric and thermal power generation - are identical in both processes. The ETVS-Process and the NTVS-Process are self-sustaining in terms of energy use; actually a surplus of heat and electricity is generated in both processes. © 2007 Elsevier Ltd. All rights reserved.

  • biomass conversion into fuel gas using circulating Fluidised Bed Technology the concept improvement and modelling discussion
    Renewable Energy, 2003
    Co-Authors: G Chen, J Andries, H Spliethoff
    Abstract:

    Abstract Fuel gas production from biomass using circulating Fluidised Bed Technology is presented in our laboratory. This improved technical concept is aiming at producing high quality gas, in terms of low tar level and particulates carried out in the fuel gas, and overall emissions’ reduction associated with fuel gas combustion, as well as stable and reliable operation with the minimum fluctuations in the producer gas volume and composition. Based on this concept, a characteristic theoretical modelling approach involving hydrodynamics, chemical reaction kinetics, and energy balance is accordingly discussed. In addition, very preliminary experimental results from a laboratory-made test rig are also given.
