3t/d石炭ガス化研究炉によるプラスチック粉末混合が石炭ガス化に及ぼす影響把握

抄録

In Central Research Institute of Electric Power Industry (CRIEPI), we are developing the basic technology for a polygeneration system with CO₂ capture utilizing various fuels such as coal, waste plastic and biomass. The system is using an O₂/CO₂/H₂O blown gasifier for producing syngas. We investigated the effect of adding plastic to coal on gasification performance experimentally using 3t/d coal research gasifier. The gasifier is pressurized, two-stages composed of a combustor and a reductor, and entrained-bed type. In this study, we evaluated the gasification characteristics of a plastic fuel that fed into the combustor and the reductor respectively. It is clarified that plastic fuel fed into the combustor is more effective for higher carbon conversion than fed into the reductor in this polygeneration system.
