Integrated gasification combined cycle (IGCC) was evaluated as high-efficiency and eco-friendly power generation technology. Depending on the methodology of coal supply system, the gasification systems can be classified with dry-feeding and wet-feeding, and two system obviously have their own advantages and disadvantages. For dry feeding system, it is more efficient than wet-feeding system because of supplying the high coal concentration. However, the other facilities for drying the coal was required to supply coal continuously to gasifier. On the other hands, wet-feeding system is possible to supply the coal with high pressure using the slurry feeding pump and its system configuration is simple. In this research, coal slurry feeding system using the pressure difference control was developed and conducted the experiments to find out the operation characteristics. Coal slurry feeding system consist of supply hopper and refill hopper, and high pressure nitrogen gas was supplied to each vessel to control the operating pressure by pressure difference. In conclusion, the coal slurry feeding system using the pressure difference control was confirmed that it can supply the coal slurry continuously without pulsation. Moreover, the feed rate of coal slurry was increased consistently depending on increasing the differential pressure between supply hopper and refill hopper and coal slurry feeding flow rate was 63.08 kg/hr in supplying differential pressure of 2bar.
