Verfahren zur gestuften Verbrennung von Brennstoffen

WO 200233317 A UPAB: 20020618 NOVELTY - The method involves subjecting solid fuel to combustion , partial combustion or gasification in combustion chamber (3) in oxygen atmosphere below stoichiometric conditions; supplying additional oxygen to combustion space in transition region between combustion chamber and furnace (7) in a quantity above stoichiometric conditions, and adding a catalyst (8,9) to improve or accelerate reactions in the region to which the amount of oxygen above stoichiometric conditions is also supplied. DETAILED DESCRIPTION - The catalyst can be a ferro-oxidic catalyst, such as a finely dispersed iron oxide. USE - for burning non-homogeneous solid fuels with low toxic emissions ADVANTAGE - prevents formation of inert nitrogen
