The Low Temperature CFB Gasifier - Further Test Results and Possible Applications
Abstract
Thenovel"LowTemperatureCirculatingFluidisedBed"(LT-CFB)gasificationprocessisdescribed together with the most recent results from the 50 kW LT-CFB test plant located at the Technical University of Denmark.The LT-CFB concept aims at avoiding problems due to ash sintering/agglomeration and corrosion when using difficult fuels such as agricultural biomass and many waste materials. This is achieved by pyrolysing the fuel at around 650°C in a circulatingfluidised bed(CFB)chamberandsubsequently gasifyingthechar downto only around 730°Cin aslowly fluidised bubbling bed (BFB) chamber located in the CFB particle re-circulation path.The 50 kW test plant was built and commissioned during 1999 and since then experiences have been gained from more than80hoursofoperation. Nearlyallofthetest workhasbeenperformedonfuelthatisexpectedtobe worst-case conditions, i.e. the fuel has mainly been Danish wheat straw containing 1,8 % potassium and 0,8 % chlorine (dry basis) and the bed material has been ordinary silica sand with no additives.The test results have showed a high retention of potassium (73-98%) and chlorine (23-75%) in the ash. At the same time the char loss was approx. 3,5 mass% of supplied amount of fuel, and the content of PAH in the ash was only around 2 mg/kg. The most recent test results and anticipated applications are described in this paper.Keywords: gasification, biomass conversion, circulating fluidised bed (CFB)
