Application of Direct-Fired Automatic Ignition System
Application of Direct-Fired Automatic Ignition System
The direct-fired automatic ignition system replaces the conventional ignition and “permanent light” system. The direct-fired automatic ignition system uses the products of an elevator electric arc and catalytic reactor, which is installed on the upper end of the burner of the release tower, and directly ignites the released blast furnace gas.
The direct-fired automatic ignition system is a high-altitude automatic ignition system that directly uses the blast furnace gas released from the vent tower as fuel gas, which solves the problems of liquid blockage, dust blockage, sulfuration, chlorination, oxidation of fuel gas pipelines and other problems that may be caused by the use of fuel gas, and also can not consider the problems of heat tracing and insulation. Moreover, the direct-fired automatic ignition system has strong adaptability. It has loose requirements for the impurity and water content in the discharged gas. As long as the water and impurity content in the discharged gas meets the enterprise emission standards, it can adapt.
The direct-fired automatic ignition system can burn stably without using other fuel gas for ignition and tracing, which changes the status quo of the traditional use of other high-calorific value fuel gas as ignition and tracing, thus making the operating cost of blast furnace gas emission combustion treatment basically zero. The direct-fired automatic ignition system does not have any process pipes and is simple to install, with a small investment in public works, and basically without operation and maintenance.
The direct-fired automatic ignition system has been used in iron and steel enterprises for many years and has achieved the expected goal of zero use fee of purchased fuel under the premise of ensuring safe operation. At present, the technology of direct-fired automatic ignition systems has been widely concerned and actively quoted by iron and steel enterprises.
The direct-fired automatic ignition system uses a new type of high-altitude igniter and plasma igniter. The plasma igniter generates 25000 V DC high voltage and is delivered to the high-altitude igniter. There are burners, arc-pulling devices, and catalytic combustion devices in the high-altitude igniter. A large number of arcs are generated by the arc-pulling device, and the ionizing burner ionizes the air to generate plasma. At this time, the incoming converter gas is directly burned in the high-temperature and high-pressure environment, At the same time, the catalyst of the catalytic burner will produce a large amount of oxygen to maintain the continuous combustion of the high-altitude ignition head.
