Abstract
A power generation system including a gasifier for receiving and converting coal-water slurry to a fuel stream, and a quench device for cooling the fuel stream to generate a cooled down fuel stream. The quench device includes a water quench ring, which is able to spray water to cool the fuel stream passing therethrough. The system further includes a separating device, which includes a separator and a high temperature filter for removing rough and fine particles from the cooled down fuel stream respectively, an expander for receiving and utilizing energy in the fuel stream with solids removed to generate power, during which temperature and pressure of the fuel stream drop and an expanded fuel stream is generated, an acid gas removal unit for removing acid gases from the expanded fuel stream, and a gas turbine combine cycle for generating power from the fuel stream with acid gases removed.
