Abstract:
Besides the quantification of tar in the producer gas, it is essential to identify the compounds that are detrimental for the system performance. In particular, internal combustion engines are sensitive to the heavy tars, that create heavy residual depositions in the engine manifold, intake valves, turbo-compressor and on the cylinder wall. This study considers a gasification system, fixed bed gasifier coupled with ICE, of small scale (100-150 kWel). The system has been investigated in order to identify deposition of tar across the producer gas path, from the gasifier to the engine. Cleaning and removal of these depositions result in regular interruption of plant’s functioning. The collected depositions of tar have been analysed by means of calorimetric and thermogravimetry analysis, x-ray fluorescence spectrometry (XRF), gas-chromatography (GC) and mass spectrometry (MS), to identify the primary constituents. Furthermore, the characterization of the tars in the producer gas, after the clean-up section, has been carried out in accordance with the European protocol UNI CEN/TS 15439-2008. The results have been discussed and they provide an insight of the tar issue on the real scale plant systems. Further research is needed to identify the compounds that are more detrimental for the operation of the gasification systems.
