A cremator (1) comprises a primary combustion chamber (10) for receiving through a charge door (14) thereof a coffin or other object to be cremated and being provided with a first burner (50), a secondary combustion chamber (20) (e.g. in the form of a tube of thermally conductive material) in communication with the primary combustion chamber (10) and being provided with a second burner (60), and a retention chamber (30) in communication with the secondary combustion chamber (20) for temporarily retaining heated waste gases exhausted from the secondary and primary combustion chambers (20;10) before passing to a waste flue (80), characterised in that at least a portion of the secondary combustion chamber (20) is located within the retention chamber (30), whereby gases retained in the retention chamber (30) are heated (preferably to a temperature of at least 850 DEG C) at least partly by direct heating from the secondary combustion chamber (20). This improved constructional design provides for a more compact and fuel-efficient dual combustion chamber-type cremator. <IMAGE> |
