The natural gas injection in the Q-BOP design is shown. However, as previously indicated, this is not a combustion process per se, the fuel provides cooling by cracking into hydrogen and carbon monoxide. The carbon monoxide is carried through to the exhaust gases, while the hydrogen is absorbed in the melt.
