Embodiment Construction

[0014] like figure 1 As shown, the present invention includes a combustion chamber 1, a burner 8, a retractable automatic ignition device 2, a forced convection generating device, a machine box 4, and a fuel supply chamber. The combustion chamber 1 is in the shape of a cuboid, and the ventilation duct 6 is in the shape of a right angle as a whole, and the right angle is a circular arc transition, which is installed inside the combustion chamber 1. A blower fan 5 is fixed at the place, placed horizontally, two pieces of the microporous aluminum honeycomb core 3 are arranged up and down above the blower fan 5 in the combustion chamber 1, and there is a certain distance between the two pieces of the microporous aluminum honeycomb core 3, and the microporous aluminum honeycomb core 3 The porous aluminum honeycomb core 3 is a rectangular parallelepiped porous flat plate, which is fixedly connected to the side wall of the combustion chamber 1. The upper part of the microporous alumi...

Abstract

The invention discloses an experimental apparatus for diffusion flames in a forced convection environment. The apparatus can be used for studying the influence of forced-convection velocities on the characteristics such as height, width, color, oscillation frequency and the like of diffusion flames. The experimental apparatus disclosed by the invention is concretely characterized in that a forcedconvection generation device is added into the existing experimental apparatus for diffusion flames, and the existing ignition device is replaced with a retractable automatic ignition device, so thatthe ignition device does not affect a forced convection environment created by the invention. The experimental apparatus disclosed by the invention has an important significance to the study on the combustion mechanism of diffusion flames.

Description

technical field [0001] The invention relates to a diffusion flame experiment device, in particular to a diffusion flame experiment device in a forced convection environment. Background technique [0002] One of the main influencing factors of the diffusion flame combustion environment is the forced convection condition. The study of the influence of the forced convection condition on the characteristics of the diffusion flame height, width, color, and oscillation frequency is of great significance for the in-depth understanding of the combustion mechanism of the diffusion flame and the application of fire image detection technology. It is of great significance, but there is no suitable device for how to obtain the characteristics of the diffusion flame under different flow fields. At present, researchers at home and abroad mostly conduct diffusion flame experiments in the combustion chamber. Existing diffusion flame devices include combustion chambers, diffusion flame genera...
