Disposal of mixed waste by low temperature carbonisation and combustion

摘要

This new method operates a low temperature coking and combustion plant (2). Waste (A) is fed to the coking drum (10), where hot gases raise its temperature. Pyrolysis residues (p) and/or gases (s) liberated are fed with fresh air (f), to the burner (30) of a high temperature combustion chamber (32). The novel feature is mixing of hot gas (h') leaving the coking drum, with the air (f) for the burner (30) of the high temperature combustion chamber (32). Also claimed is the corresponding soft coking and combustion plant. It includes a mixing zone (60) in which part of the heating gas (h') is mixed with air (f) for the burner (30).
