Replace combustor with a high compression engine, and it might be worth the otherwise pointless gasification stage.

The designers were probably worried about the volumetric energy density of the gas, but all that goes out the window when you can put a bigger compressor to compensate.

>Would cooling really be a major problem?
The soot isn't going to damage anything as long as the engine is hot enough to avoid excessive deposition there, and it would actually lubricate if the engine was still cool enough to allow a thin layer of soot to form. (If we could do away with splash lubrication in an engine, that would probably be a significant gain.) However, the efficiency will go down if soot deposits are excessive anywhere in the system, which will require a cleanout as >>2532826 mentions.

Inappropriate cooling has plagued engine building since steam, where the flame was in thermal contact with the boiler in older designs, then again with non-regenerative cooling in IC piston engines which continues to this day.
