  • Low NOx mixed injector
    Patent number: 9169148
    Abstract: The invention relates to a combustion method for glass melting, in which a flame is created both by a liquid fuel pulse and a single gaseous fuel pulse, characterized in that the fraction of the total power due to the liquid fuel varies between 20 and 80%, and in that the specific gaseous fuel pulse is limited to a value that is sufficiency low so that the NOx content of the flue gases produced does not exceed 800 mg/Sm3 for a cross-fired furnace and 600 mg/Sm3 for an end-fired furnace; an injector for implementing this method; a burner comprising one or more such injectors; a furnace comprising at least one such burner.
    Type: Grant
    Filed: May 6, 2008
