Abstract
A combustion ash handling method of handling combustion ash discharged from a combustion furnace that combusts a petroleum-based fuel includes: separating the combustion ash into a heavy component and a light component by a dry-type separation technique; feeding the light component to the combustion furnace as a fuel; and recovering the heavy component. A metal such as vanadium is separated and extracted from the heavy component of the combustion ash.
Claims11
A combustion ash handling method of handling combustion ash discharged from a combustion furnace that combusts a petroleum-based fuel, the combustion ash handling method comprising:
- separating the combustion ash into a heavy component and a light component by a dry-type separation technique;
- feeding the light component to the combustion furnace as a fuel;
- and
- recovering the heavy component.
A combustion ash handling system for handling combustion ash discharged from a combustion furnace that combusts a petroleum-based fuel, the combustion ash handling system comprising:
- a dry-type separator that separates the combustion ash into a heavy component and a light component;
- a light component transfer line that feeds the light component to the combustion furnace as a fuel;
- and
- a recovery container that recovers the heavy component.
