Embodiment 1

[0053] For a blast furnace hot blast stove renovation project, there are four traditional horizontal sleeve burner top-fired hot blast stoves, please refer to Figure 5 , (only one is shown in the figure, and the other three are the same). Remove the original traditional horizontal sleeve burner, install the double-channel vortex ceramic burner of the present invention on the upper part of the combustion chamber of the traditional horizontal sleeve burner top-fired hot blast stove, and replace the original traditional horizontal sleeve burner with top-fired hot air The gas pipe and the air pipe of the stove are respectively connected to the gas inlet 4 and the air inlet 6 of the dual-passage vortex ceramic burner of the present invention, refer to Figure 5 , that is, the renovation project is completed.

Abstract

The invention relates to a double-channel vortex ceramic burner (namely, the number of coal gas inlets is two and the number of air inlets is two) which is vertically installed at the upper part of a burning chamber of a hot air stove and comprises a vortex chamber 1, a throat mouth 8, coal gas inlets 4, a coal gas ring path 3, a coal gas nozzle 2, air inlets 6, an air ring path 7 and an air nozzle 5, wherein the vortex chamber 1 is positioned at a central area, and the throat mouth 8 is arranged between the vortex chamber 1 and the burning chamber; the coal gas nozzle 2 is arranged on the inner wall of the coal gas ring path 3, and two coal gas inlets 4 are arranged on the outer wall of the coal gas ring path 3; the air nozzle 5 is arranged on the inner wall of the air ring path 7; and the two air inlets 6 are arranged on the outer wall of the air ring path 7. The double-channel vortex ceramic burner can transform the top-burning hot air stove of the traditional level sleeve type burner into a vortex top-burning hot air stove under the condition that the burning chamber and the pipeline of the hot air stove is rarely transformed. The double-channel vortex ceramic burner has the characteristics of raising the hot air temperature, prolonging the service life of the hot air stove, reducing the burning consumption, and reducing the investment.

Description

technical field [0001] The invention relates to a hot blast stove burner in the technical field of iron and steel metallurgy and energy saving, in particular to a dual-channel vortex ceramic burner which can significantly save investment and improve the efficiency of the hot blast stove and the temperature of the air supply. Background technique [0002] Hot stove is [0003] A facility that supplies hot air to an ironmaking blast furnace. Its working principle is to generate high-temperature flue gas by burning gas through the burner of the hot blast stove, heat the regenerator in the hot blast stove, and then the cold air passes through the regenerator and exchanges heat with the regenerator to become hot air (high temperature air) According to the position of the burner, the hot blast stove can be divided into various structural forms such as internal combustion type, external combustion type and top combustion type. Existing technologies for top-burning hot blast stove...
