4. Fremgangsmåde ifølge et af kravene 1 til 3, kendetegnet ved, at strømningshastigheden for den anden oxygenholdige strøm (4) overstiger strømningshastigheden for den anden brændstof strøm (3) med mere end 50%, fortrinsvis med mere end 75%, særligt foretrukket er mellem 90% og 120% af strømningshastigheden for den anden brændstofstrøm (3).
5. Fremgangsmåde ifølge et af kravene 1 til 4, kendetegnet ved, at der omsættes et flydende eller fast brændstof, navnlig kul, brunkul eller træ.
6. Fremgangsmåde ifølge et af kravene 1 til 5, kendetegnet ved, at den første (2) og/eller den anden oxygenholdige strøm (4) indeholder en blanding af oxygen og kuldioxid, navnlig består af en blanding af oxygen og kuldioxid.
