PROCESS AND APPARATUS FOR TREATMENT OF INCINERATOR BOTTOM ASH AND FLY ASH |
摘要 |
A method for treatment of ash from incineration plants includes: collecting ash from an incinerator; feeding the collected ash and additional feed material to a gasification/vitrification reactor; vitrifying the ash and additional feed material in the gasification/vitrification reactor, to form a slag of molten material; allowing the slag to flow from the gasification/vitrification reactor and solidify outside the gasification/vitrification reactor; gasifying volatile components in the ash and the additional feed material; combusting syngas generated in the gasification/vitrification reactor in a secondary combustion zone in the gasification/vitrification reactor; and supplying products of the syngas combustion to the incinerator to augment the thermal environments of the incinerator. An apparatus used to practice the method is also provided. |

1. A method for treatment of ash from incineration plants, the method comprising:
collecting ash from an incinerator; feeding the collected ash to a gasification/vitrification reactor; vitrifying the ash in the gasification/vitrification reactor, to form a slag of molten material; allowing the slag to flow from the gasification/vitrification reactor and solidify outside the gasification/vitrification reactor; gasifying volatile components in the ash; combusting syngas generated in the gasification/vitrification reactor in a secondary combustion zone in the gasification/vitrification reactor; and supplying products of the syngas combustion to the incinerator to augment the thermal environments of the incinerator. |
