Method for regenerating filter and apparatus thereof |
摘要 |
A filter regeneration apparatus of a coal gasification system having a filter for capturing char (unburned matter) present in exhaust gas at an exhaust gas passage communicating with exhaust gas source including a coal gasification furnace, fills the filter container with inactive gas having oxygen concentration of less than 5 vol. % and heat the filter to a target temperature of 400 to 450° C. and feed ashing gas having oxygen concentration of 5 to 15 vol. %, thereby ashing char in the filter. This method and apparatus achieve ashing of char in a safe manner and shortens the time of regenerating the filter by controlling the oxygen concentration in the ashing gas and the filter temperature constantly to reach preset target values.
