Sewage sludge and digestate gasification in an atmospheric fluidized bed gasifier
Original language description
The gasification of sewage sludge (SS) and digestate was investigated in a pilot-scale fluidized bed gasifier with an outputof 100 kWt. The treatment of these by-products is an ongoing challenge for sustainable development. SS and digestate aremost commonly used as fertilizers. However, regulations restrict their use, mainly because of the content of heavy metals,pathogens and bacteria. Gasification of these by-products instead of application to agricultural land seems to be more effi-cient, as the syngas can subsequently be used for combined heat and power (CHP) generation. A series of measurementswere carried out to get a better understanding of the gasification process of these fuels and to study the effects of gasifyingagent on the syngas composition, particulate matter (PM) and tar. The produced syngas and tar were analyzed using a gaschromatograph with mass spectrometry (GC–MS). The results showed that no ash slagging was observed and therefore itis feasible to operate digestate and SS gasification at 750°C. The lower heating value (LHV) of the syngas from digestateand SS with air as the gasifying agent is comparable, 4.06 MJ·Nm−3 for digestate and 4.11 MJ·Nm−3 for SS. The additionof steam had a positive effect on the amount of tar and the tar dew point, which was below 150°C. Tar reduction in digestatewas 5037.3 mg·Nm−3 to 3566.3 mg·Nm−3 and in SS 7447.7 mg·Nm−3 to 3390.3 mg·Nm−3. Furthermore, the concentrationsof the individual tar compounds were determined and subsequently divided into tar classes.
