Rotary bottom ash regeneration system

A rotary bottom ash regeneration (RBAR) system for processing bottom ash having reactant particles of a circulating fluidized bed furnace comprising:

• a cylindrical body adapted to receive said bottom ash at an inlet end and rotate;
• at least one sensor disposed within the cylindrical body adapted to measure a physical condition, and create at least one output signal representing the measured physical condition;
• at least one spray nozzle adapted to receive a regeneration fluid and to spray the regeneration fluid onto the bottom ash in the cylindrical body;
• a fluid actuator coupled to the at least one spray nozzle adapted to spray a specified amount of regeneration fluid in the cylindrical body;
• a control unit coupled to the sensors and the fluid actuator adapted to:
• receive the sensor output signal and an input regarding the mass of the bottom ash in the cylindrical body,
• calculate an amount of regeneration fluid to be provided to the cylindrical body, based on the measured physical condition and the input regarding the mass of the bottom ash, and
• activate the fluid actuator to provide the calculated amount of regeneration fluid to the bottom ash in the cylindrical body.
