Method and facility for refuse incineration using a fire-grate-type incinerator and with separation of non-combustibles

An incineration facility comprising a preprocessing facility comprising a first comminutor for comminuting combustible into comminuted combustible, a sorter for sorting metal from the comminuted combustible, a separator for separating non-combustibles from the comminuted combustible, a secondary comminutor for secondarily comminuting the comminuted combustible after the separation from the non-combustible, and a classifier for classifying the secondarily comminuted combustible into coarse combustible and fine combustible;

• a refuse incinerator formed with a primary combustion chamber on a fire grate and with a secondary combustion chamber above the primary combustion chamber;
• a coarse combustible supply line for supplying the coarse combustible separated by said classifier to the primary combustion chamber of the refuse incinerator;
• and a fine combustible incineration supply line for supplying as fuel said fine combustible to a combustion burner mounted in the second combustion chamber of the refuse incinerator, an ash furnace equipped with a fusion burner for heating and melting incineration residue discharged from the refuse incinerator to thereby produce slag, and a fine combustible fusion supply line for supplying coarse combustible separated by the classification process as fuel to the fusion burner.
