Abstract
Disclosed is a low NOx premixed hydrogen burner including: a plenum chamber including an inlet pipe and an outlet pipe and for mixing hydrogen and combustion air introduced through said inlet pipe to generate premixed gas for flame formation, in which a diameter of said plenum chamber is larger than diameters of said inlet pipe and the outlet pipe, and a length of said plenum chamber is greater than the diameter of said plenum chamber.
Claims18
A low NOx premixed hydrogen burner comprising:
- a plenum chamber comprising an inlet pipe and an outlet pipe and configured to mix hydrogen and combustion air introduced through the inlet pipe to generate premixed gas for flame formation,
- wherein a diameter of the plenum chamber is larger than diameters of the inlet pipe and the outlet pipe, and
- wherein a length of the plenum chamber is greater than the diameter of the plenum chamber;
- and
- an inner cooling air supply pipe installed to extend through an interior of the plenum chamber to the outlet pipe of the plenum chamber, and configured to flow outer cooling air through and cool premixed gas in the plenum chamber;
- wherein a flow velocity and pressure of inner cooling air in the inner cooling air supply pipe is formed to be greater than a flow velocity and pressure of hydrogen burner premixed gas at a full load.
