The invention discloses a support plate stabilizer structure for enhancing fuel oil atomization and suitable for an afterburner, which is used for improving the fuel oil atomization effect and the combustion stability, and comprises two support plate outer edge frames, a support plate tail edge frame, a fuel oil injection rod and the like, and a support plate mixing channel is formed between the two support plate outer edge frames; and a plurality of cooling air cavities are formed in the main body part so as to prevent key parts from being ablated in a high-temperature environment. First fuel oil impacts the fan-shaped channels through the oil injection holes to form an oil film, is further atomized under the shearing action of airflow and is mixed with air, and premixed gas is formed and then enters the concave cavity to be combusted. According to the design, flames in the concave cavity can be kept stable under the extreme conditions of low temperature, low pressure and the like, so that the ignition and flameout boundary of the combustion chamber is widened, meanwhile, high-temperature fuel gas in the concave cavity can heat transverse jet flow of second fuel oil, and the evaporation and mixing efficiency of the second fuel oil is improved. By means of the integrated design, the number of components is reduced, the flow resistance in the non-stress-application state is reduced, and meanwhile the thrust-weight ratio is increased.

This invention discloses a radial flame stabilizer with airflow-assisted jet, comprising an outer wall and an inner wall. Both the outer and inner wall surfaces have V-shaped cross-sections, including a pointed tip and two tail ends. The two corresponding tail ends of the outer and inner wall surfaces are connected by a flow-rectifying wall. An air-guiding groove is provided at the pointed tip of the outer wall, and several injection holes are provided near the tail ends. The air-guiding groove, the interlayer between the outer and inner wall surfaces, and the injection holes form an airflow channel. A fuel injection extension pipe is provided near the tail ends of the inner wall, extending from the inner wall towards the injection holes. The fuel injection extension pipe guides the fuel injection from the injection holes. By introducing a portion of the incoming flow through the air-guiding groove at the stabilizer head, and utilizing the method of coaxial injection of the introduced incoming gas and fuel, the problem of shallow fuel jet depth and difficult evaporation under high-speed, large-flow conditions is improved, resulting in better fuel evaporation and mixing performance compared to conventional radial flame stabilizers.

This invention discloses a high-precision natural gas-hydrogen blending ratio adjustment system, comprising a natural gas pipeline with a slot on its periphery, a hydrogen pipeline installed at the slot, a first inlet and multiple orifices at the upper and lower ends of the hydrogen pipeline, respectively, and a cylinder rotatably fitted at the middle of the lower end of the hydrogen pipeline. Baffles corresponding to the multiple orifices are installed on the periphery of the cylinder, and a slot is formed inside the lower end of the hydrogen pipeline. This invention, through a designed driving component, can drive multiple teeth to rotate, causing the cylinder to rotate synchronously, thereby driving the multiple baffles to rotate synchronously. This allows for adjustment of the blocking gaps between the multiple orifices as needed, achieving control over the hydrogen flow rate, effectively reducing uneven mixing of natural gas and hydrogen, and improving the blending efficiency of natural gas and hydrogen.
