Abstract
A combustion burner using hydrogen as the primary fuel and including a burner housing, a hydrogen fuel conduit extending within the housing and defining a hydrogen fuel exit opening, a combustion air conduit extending within the housing and defining a combustion air exit opening, a hydrocarbon fuel conduit defining a hydrocarbon fuel exit opening, and a mixing/combustion zone in which the hydrogen fuel, the combustion air, and the hydrocarbon fuel mix and combustion takes place. The hydrocarbon fuel exit opening is positioned such that the hydrocarbon fuel is heated prior to mixing with the combustion air injected from the combustion air opening. Also, a method of firing a combustion burner using hydrogen as the primary fuel, where hydrogen fuel, combustion air, and hydrocarbon fuel are injected into a mixing/combustion zone of the combustion burner such that the hydrocarbon fuel is heated prior to mixing with the combustion air.
