Use of bi-products from foundries as bed material in waste incineration

The project is an innovation project which aims to investigate if bi-products from foundries kan be used as bed material in fluidized beds in waste incineration plants. Since the bi-products contain iron it is possible that they can act as oxygen carriers. Bed material with oxygen carrier characteristics has in previous studies proven to have a positive effect on the combustion in terms of reduced emissions of carbon monoxide and nitrogen oxides. The project has potential to decrease deposition of material and the use of virgin raw material.
