Description

technical field [0001] The invention relates to a conical flame burner suitable for studying the combustion characteristics of liquid fuel and a method thereof. Background technique [0002] Traditional methods for studying the combustion characteristics of laminar flames include stagnant surface method, constant volume bomb method and plane flame method, among which stagnant surface method is difficult to determine the shape of the flame front, which brings great difficulties to the calculation of flame elongation rate, and In the case of high Reynolds number, it will limit its measurement of flame speed; the constant volume bomb method has a complex structure, and each experiment is only completed in an instant, which cannot provide a continuous flame that can be observed; the flame heat loss in the plane flame method is large, Affecting the laminar flame rate, the measurement error between different planar flame burners is large. These methods have their own defects, eit...

[0002] The traditional methods for studying the combustion characteristics of laminar flames include stagnant surface method, constant volume bomb method and plane flame method, among which stagnant surface method is difficult to determine the shape of the flame front, which brings great difficulties to the calculation of flame elongation rate, and In the case of high Reynolds number, it will limit its measurement of flame speed; the constant volume bomb method has a complex structure, and each experiment is only completed in an instant, which cannot provide a continuous flame that can be observed; the flame heat loss in the plane flame method is large, Affects the laminar flame rate, and the measurement error between different planar flame burners is large

These methods have their own defects, either complex, or there are many influencing factors, and the error is relatively large, and a continuous, stable and reliable flame cannot be provided for research. A conical flame burner suitable for studying the combustion characteristics of liquid fuels that can effectively prevent the flame from being affected by natural air
