Process for staged combustion and staged combustion system.

摘要

There are provided method of staged combustion and a combustion system for carrying out the method. There is injected from a first fuel source, a first fuel having a first chemical composition and from a second fuel source, a second fuel having a second chemical composition in a combustion system such that a relative reactive concentration of hydrogen, carbon monoxide, a hydrocarbon and / or a combination of two or more hydrocarbons in the first chemical composition is different than that of the second chemical composition. In the combustion system (10), in each case a first and a second injection nozzle (12, 14) are arranged one after the other in the flow direction along the longitudinal axis of the system for injection of the first and second fuel.
