Solid and possibly liquid waste material is incinerated by a) partial combustion on the stepped grates (9, 10, 11) of the solid waste material, the latter being delivered to the rotary kiln (2) at such a high temperature, that a liquid slag is formed at the inlet of the rotary kiln, b) possibly adding liquid waste material to the solid waste material being incinerated on the stepped grates (9, 10, 11), and c) collecting the ash products from the combustion process, such as grate screenings, boiler ash, fly ash, and residual products from flue-gas cleaning, and returning these products to the input end (12) of the rotary kiln (2), at which input end these products are introduced into the liquid slag. In this manner, it is achieved that the slag, fly ash and other harmful residual products from the combustion process are fused into a glass-like mass, from which salts and heavy metal cannot be leached out. |
