Incinerator Ash

An incineration plant burns waste and may or may not recovery the energy from the heat generated.

Incineration plants:

The Incineration of waste is a successful way in helping to meet some of the requirements of the Landfill Directive. Incineration can also help reduce the reliance on other energy sources such as fossil fuels or nuclear energy.

During incineration, the volume and weight of the waste is reduced. Energy is produced which can be used for district heating and electricity generation. Where both electricity and heat are utilised from an incineration plant it may be termed a Combined Heat and Power (CHP) plant.

The waste product of incineration is known as incineration bottom ash (IBA).

Before disposal of this “waste product” valuable metals can be removed. Initially ferrous metal is extracted from the incineration bottom ash (IBA) with overband magnets and then drum magnets. IBA material can then be feed to an eddy current separator for recovery of non ferrous metals.

The IBA can be used as a secondary aggregate in construction projects or disposed of to landfill as inert waste.

Incinerator ash (also know as IBA or bottom ash) includes a complex range of metals and requires special processing

Magnapower manufacture a comprehensive range of equipment for metal recovery from bottom ash (IBA) including:

Magnapower recognise the need for product quality and purity. We focus our experience and knowledge of this application to provide separation equipment which leads the industry.

Typical application – Recovery of ferrous and non ferrous metals from IBA (bottom ash).

Separation processes will vary depending on materials / size and can include:

Stage 1

Stage 2

Stage 3
