发明名称 Method and burner tip for suspressing emissions of nitrogen oxides
摘要 A method and burner tip for suppressing the production of oxides of nitrogen when burning a fuel in a combustion chamber containing a flame zone are described. The burner tip comprises at least one port for introducing fuel into the combustion zone and at least one port for introducing a control gas into the combustion zone, where both the fuel and control gas are introduced substantially perpendicular to the direction of introduction of combustion gas into the combustion zone. The ports are laterally spaced apart from each other. The control gas is used for controlled localized quenching of the flame zone and/or for controlled atomization of the fuel in the case of a liquid fuel to reduce the emissions of nitrogen oxides (NOx). By proper selection of the size and location of the fuel and control gas ports, and the quantity and velocity of the fuel and control gas introduced into the combustion zone, a stable flame with minimal emission of oxides of nitrogen can be obtained.
