Abstract

A novel biomass slagging gasifier has been developed under the European JOULE programme. The main objective of the project was to develop an innovative, reverse flow molten slag fixed bed gasifier concept for combined heat and power generation in a capacity range of 0.5-2.5 Mwe, and with improved thermal efficiency (increase of 5 - 10%) compared to conventional fixed bed gasifiers. The reactor enables handling of relatively wet (up to 40 % mcdb) and ash-rich biomass fuels with a low ash-melting point. The gasifier produces a gas with a caloric value of at least 6 MJ/Nm3. This paper presents some experimental results obtained with the pilot-plant gasifier (20 kg biomass throughput per hour). The technical feasibility of the reverse flow gasifier has been demonstrated. The gasifier enables the production of a tar-free gas at low temperature, slag granulates and medium pressure steam.
