The invention relates to a premixed oxygen-enriched combustion system for a heating furnace, which includes a heating furnace, a fuel system, and a combustion-supporting system. The heating furnace includes a preheating section, a heating section, and a soaking section. The bottom straight flame burner, the soaking section is equipped with a flat flame burner in the soaking section, and a straight flame burner in the bottom of the soaking section; the combustion system includes an oxygen pipeline, an oxygen valve group, and a premixed oxygen-enriched combustion system 1. Premixed oxygen-enriched combustion In the second system, the oxygen in the oxygen pipeline is respectively supplied to the premixed oxygen-enriched combustion system one and the premixed oxygen-enriched combustion system two through the oxygen valve group. The invention combines the original combustion system of the steel rolling heating furnace with the premixed oxygen-enriched combustion technology, and realizes the oxygen-enriched combustion of the whole furnace through the control of different oxygen concentrations by different burners of the premixed oxygen-enriched combustion system, thereby improving the combustion efficiency and heat transfer of the heating furnace Efficiency, to increase production capacity, save fuel, reduce emissions and reduce investment costs.
Description
technical field [0001] The invention relates to the technical field of heating furnaces, in particular to a premixed oxygen-enriched combustion system and method for a steel rolling heating furnace. Background technique [0002] Oxygen-enriched combustion technology has high conduction efficiency and combustion efficiency in the heating furnace field, which can improve the production capacity of the heating furnace, save fuel, and reduce NOx and C0 2 Emissions and many other advantages, the application prospect is very broad. [0003] At present, there are several methods of oxygen-enriched combustion in steel rolling heating furnaces: air and oxygen are pre-mixed and then supplied to the burner for combustion, oxygen-inserted oxygen-enriched combustion, pure oxygen-enriched combustion, and flue gas backflow oxygen-enriched combustion. For traditional heating furnace burners, air and oxygen are pre-mixed and supplied to the burner for combustion. High oxygen concentration w...
