Abstract
In a method of burning a nitrogen-containing fuel while reducing the emission of nitrogen oxides is provided, a sub-stoichiometric primary zone in the form of a flame core is produced and is supplied with a nitrogen oxide reducing agent that is a nitrogen compound or a hydrocarbon. Preferably, the flame core consists of a single zone and has a uniform air to fuel ratio.
Claims10
A method of burning a nitrogen-containing fuel while reducing the emission of nitrogen oxides, said method including the steps of:
- producing a flame core from all of the fuel and primary air, wherein said flame core comprises a sub-stoichiometric primary zone having a uniform air to fuel ratio;
- and
- supplying said flame core with a nitrogen oxide reducing agent so that said reducing agent is distributed within said flame core, wherein said reducing agent is a nitrogen compound or a hydrocarbon.
