On the basis of studies, the method for thermal utilization of wastes, consisting of co-incineration of fuel mixtures in existing power boilers was developed. Installations were designed for three groups of materials which will make two-component mixtures with coal: rubber from scrap tyres, sewage wastes (sewage slurry dewatered mechanically and thermally dried out), RDF fuel gained from burnable fraction of municipal wastes. Rubber due to its properties can be co-incinerated only in stoker fired boilers. The existing installations of power plants are suggested to be used for thermal utilization of wastes. Such installation are the dust and stoker fired boilers equipped with technically advanced system for wet and semi-wet off gases desulfurization, so they can meet European emission standards. Feeding system for wastes to be burned is the problem to be solved.
