In Central Research Institute of Electric Power Industry (CRIEPI), we are developing the basic technology for a poly-generation 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 powder to coal on gasification performance experimentally using 3t/d coal research gasifier. The gasifier is two-stages composed of a combustor and a reductor, and entrained-bed type. We evaluated the gasification characteristics of a plastic fuel that fed into the combustor and the reductor respectively. It is found that gasification performance increased by adjusting the position of plastic injection. 3t/d coal research gasifier was added a pellet fuel feed system. Gasification tests were conducted with mixed fuels of coal and pellet fuel (RPF: Refuse derived paper and plastics densified Fuel) and it was confirmed that the gasification performance was improved when using pellet fuel as well as the plastic powder.
