Abstract

Combined fuel and oxidizer metering jets for simultaneously metering the flow rate of a liquid and/or LG fuel and an oxidizer for delivery to a single or multi-fuel burner. By combining both fuel and oxidizer metering functions into a single article, a multi-fuel burner having a single type of fuel delivery conduit and mixing tube can be optimized for a variety of fuels without dynamic user modulation of oxidizer flow rate.
