Abstract
A burner for a hot-blast furnace has a guidance portion, a channel portion and a mixing portion. The guidance portion serves as an air and gas intake, and is divided into a plurality of separate compartments by thin walled plates. Some of the compartments of the guidance portion have side openings for receiving gas therein, and the other compartments have lower openings for receiving air therein. All of these compartments have exit openings at their top for delivering the air and gas to the channel portion. Conduits are provided in the guidance portion to equalize the pressures within the respective air and gas compartments. The channel portion has a plurality of channels having an overall reduced cross-sectional area of flow as compared with the guidance portion. A mixing portion is disposed above the channels, mixing the air and gas and defining a plurality of burner jets. The reduction in cross-section from the guidance portion increases the velocity of the air and gas going to the burner jets.
