SUMMARY
한국어 초록
An innovative small-scale gasification system for solid fuels such as wastes and biomass is proposed which is knownas STAR-MEET system. In this system, a fixed-bed pyrolyzer combined with a high temperature reformer using hightemperature steam/air mixture is employed. From the experimental results using rubber chips as a fuel, it has beendemonstrated that injection of high temperature steam/air mixture into the pyrolysis gas effectively decomposes tar andsoot components in the pyrolysis gas into CO and H 2' and almost dust and tar free clean reformed gas can be generated.The STAR-MEET system requires high temperature steam/air generator, and a 900C class metallic type compact heatexchanger has been successfully developed. This gasification system generates low BTU gas from solid fuels. Thuspower generation experiments using a dual fueled(light oil gas and low BTU gas) small diesel engine were done using asimulated low BTU gas produced from natural gas diluted with nitrogen. Compared with light oil only driven, dualfueled engine shows similar thermal efficiency with significantly low NOx emission. Finally, power generationexperiments using a complete STAR-MEET plant has been successfully done. These results demonstrates small-scalegasification and power generation system using solid fuels is quite feasible.영어 초록

temperature steam/air mixture is employed. From the experimental results using rubber chips as a fuel, it has been
demonstrated that injection of high temperature steam/air mixture into the pyrolysis gas effectively decomposes tar and
soot components in the pyrolysis gas into CO and H 2' and almost dust and tar free clean reformed gas can be generated.
