Super-Nichtstöchiametrisches Verbrennungsverfahren

摘要

The combustion method involves forming a rich stream by injecting into a combustion zone first oxidant, being a fluid having an oxygen concentration of at least 30 vol. per cent, and first fuel in a ratio within the range of from 5 to 50 per cent of stoichiometric. A lean stream is formed by injecting into the combustion zone second oxidant and second fuel in a ratio of greater than 200 per cent stoichiometric. The first oxidant and first fuel is combusted within the combustion zone. The second oxidant and second fuel is combusted within the combustion zone and produces products of complete combustion and remaining oxygen. Remaining oxygen is mixed with combustion reaction products within the combustion zone and combusted with the combustion reaction products.
