A distinctive feature is that the incinerator contains an afterburner with a secondary burner, which is used for afterburning at elevated temperatures of soot, ash and waste gases that are contained in the resulting smoke.
The author states that the operational life of the engines was degraded because of "excessive afterburning that overheated the engine oil and fused and jammed the bearings." Since when did pisten-engine, propeller-driven aircraft sport an afterburner?
