Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a combustion stabilizing device suitable for high-pressure rotary sliding arc plasma ignition of various types of industrial burners (fuel is gas or oil). Background Art

[0002] A burner is a device that mixes fuel and air and burns them. It is widely used in industrial production, energy development, environmental protection and other fields. The performance of the burner directly affects the combustion efficiency, emission pollution, safety and reliability. Therefore, the ignition and stable combustion technology of the burner is an important part of the burner technology, and it is also a difficult and hot issue in the burner technology.

[0003] At present, the commonly used burner ignition and stable combustion technologies mainly include flame ignition, spark ignition, plasma ignition, etc. Among them, plasma ignition technology is a technology that uses high-temperature and high-energy plasma to ignite the fuel / air mixture in the burner. It has the advantages of fast ignition speed, high ignition success rate, wide ignition range, strong anti-interference ability, strong adaptability, etc. It is a very promising ignition technology.

[0004] The core of plasma ignition technology is the plasma generator, that is, a device that can generate plasma. At present, common plasma generators include arc discharge, corona discharge, dielectric barrier discharge, radio frequency discharge and other forms. Among them, arc discharge is a discharge form that can produce high-temperature and high-energy plasma. The energy density of its plasma can reach tens or even hundreds of joules per cubic meter, and the conductivity of its plasma can reach tens or even hundreds of Siemens per meter, which has a strong ignition ability.

[0005] A special form of arc discharge is sliding arc discharge, which is a discharge form in which the arc slides on the electrode surface. It is a typical representative of non-equilibrium plasma. Gliding arc discharge has the advantages of increasing the volume coverage of plasma and being suitable for high pressure. It can interact with turbulent flames for a longer time. In addition, a large number of excited particles and active groups will be generated during the sliding arc discharge process, which can increase the chemical reaction rate, accelerate the chemical reaction, strengthen combustion, and have significant effects on combustion support and stabilization. It is a very potential discharge form and has attracted widespread attention.

[0006] Gliding arc discharge can be divided into DC sliding arc discharge and AC sliding arc discharge, among which AC sliding arc discharge can be divided into rotating sliding arc discharge and oscillating sliding arc discharge. Rotating sliding arc discharge is a discharge form that uses AC power to drive the arc to rotate on the electrode surface. The rotation speed of the arc can reach tens or even hundreds of kilohertz, the rotation angle of the arc can reach tens or even hundreds of degrees, and the rotation radius of the arc can reach several millimeters or even several centimeters. It has high flexibility and controllability.

[0007] High-pressure rotating sliding arc discharge is a rotating sliding arc discharge carried out in a high-pressure gas environment. It has higher ignition and stable combustion capabilities and is suitable for burners under harsh conditions such as high pressure, high temperature, and high turbulence. However, the characteristics and mechanism of high-pressure rotating sliding arc discharge are not clear enough and require further research and exploration. There is no practical engineering application in the field of industrial burners.

[0008] At present, the application of plasma ignition in the field of industrial burners is limited to installing plasma generators in the pulverized coal burners of coal-fired boilers, using plasma arcs to directly ignite pulverized coal to start the furnace or to stabilize the boiler at low load, without starting the large oil gun, using coal instead of oil to reduce the use of fuel. Moreover, this type of plasma generator is a high-power DC balanced plasma, with a complex system, high cost, and a narrow application range. Summary of the invention

[0036] Working principle: Gliding arc discharge is a theory proposed by Lesueur and Czernichowski in 1988 (Lesueur H, Czernichowski A, Chaple J FRPatent 2639172

[1988] ). Its working principle is that under the excitation of a strong electric field, the arc generated between the two electrodes slides along the electrodes driven by the airflow, and periodically undergoes a cycle of breakdown-elongation-arc extinction-re-breakdown. Gliding arc plasma is a warm plasma between hot plasma and cold plasma. As a typical representative of non-equilibrium plasma, it has the thermal properties of both hot plasma and cold plasma. The traditional electrode structure of sliding arc discharge is a blade-type electrode structure, with two blades for the high and low voltage electrodes respectively. The electrode structure is simple and has a long life. Therefore, sliding arc plasma is widely used in the fields of volatile organic pollutant treatment, inorganic pollutant decomposition, sterilization, material surface modification, etc.

[0037] The sliding arc plasma region of the traditional blade electrode structure only exists between the two blade electrodes, which is similar to a two-dimensional plane region. In addition, the interaction time between the two-dimensional sliding arc and the medium gas is short, which limits the application of the two-dimensional sliding arc in engineering. Therefore, developing the structure of the sliding arc discharge from two dimensions to three dimensions will greatly improve the processing capacity of the sliding arc and promote the engineering application of the sliding arc. Some individuals or institutions have conducted relevant research on the three-dimensional rotating sliding arc, such as: the breakdown mechanism of the sliding arc discharge process, the difference in arc heat transfer mechanism under different current conditions, the spectral characteristics of the sliding arc, the vibration temperature and electron density, the influence of the sliding arc on the fuel atomization, the influence of the sliding arc on the flame structure, etc. The above research has laid a theoretical foundation for the engineering application of sliding arc plasma, obtained a large number of original results, and provided a reference for the subsequent research and application of sliding arc plasma.
