The application of direct ignition automatic ignition system
The direct ignition automatic ignition system replaces the conventional ignition and "constant light" systems. The direct combustion automatic ignition system uses products from elevator arcs and catalytic reactors, installed at the upper end of the release tower burner, to directly ignite the released blast furnace gas.
The direct combustion automatic ignition system is a high-altitude automatic ignition system that directly uses the blast furnace gas released from the release tower as fuel gas, solving the problems of liquid blockage, dust blockage, vulcanization, chlorination, oxidation of fuel gas pipelines that may be caused by the use of fuel gas. At the same time, it can also avoid considering issues such as heat tracing and insulation. Moreover, the direct combustion automatic ignition system has strong adaptability and loose requirements for the impurities and water content in the released gas. As long as the water and impurities content in the released gas meets the enterprise emission standards, it can adapt.
The direct combustion automatic ignition system can achieve stable combustion without using other fuel gases for ignition and co firing, changing the traditional use of other high calorific value fuel gases for ignition and co firing. As a result, the operating cost of blast furnace gas dispersion combustion treatment is basically zero. The direct combustion automatic ignition system has no process pipelines, is easy to install, has low investment in public works, and has basically no operation and maintenance.
The direct ignition automatic ignition system has been used in steel enterprises for many years, achieving the expected goal of zero fuel usage fees for external purchases while ensuring safe operation. At present, the technology of direct ignition automatic ignition system has attracted widespread attention and active reference from steel enterprises.
The direct combustion automatic ignition system adopts a new type of high-altitude ignition head and plasma igniter. The plasma igniter generates 25000 volts of direct current high voltage, which is transported to the high-altitude ignition head. The high-altitude ignition head is equipped with a burner, an arc pulling device, and a catalytic combustion device. Through the arc pulling device, a large number of arcs are generated, and the ionizing burner ionizes the air to produce plasma. At this time, the incoming converter gas is directly burned in a high-temperature and high-pressure environment. At the same time, the catalyst of the catalytic burner is combined with combustion to produce a large amount of oxygen, maintaining the continuous combustion of the high-altitude ignition head.
