What determines the amount of limestone to be added for different coal types in the pressurized gasification process of water-coal slurry?
The purpose of adding limestone is to lower the ash fusion point of coal
The purpose of adding limestone is to lower the melting point of coal ash, which needs to be determined through experiments. It is generally required that the ash fusion temperature T4 be 50–100°C lower than the operating temperature.
