Embodiment 1
[0067] Example 1: The present invention provides a system and method for measuring the temperature and volume fraction of carbon cigarette particles based on LED light sources. A system and method based on the temperature and volume fraction of the carbon cigarette particles based on the LED point light source, and the system is a measurement system with optical paths, such as figure 1 (Schematic of the system structure), the combustion device is only drawn from the burner 11.
[0068] In this embodiment, the combustion device is used to select a laminar diffusion combustion device, a laminar flow diffusion burner, a ignition, a gas path of gas and air; gas is used to use ethylene gas, laminar diffusion combustor for providing a combustion temperature of laminar burning flames. Field and carbon smoke concentration field.
[0069] In the measurement system provided with the optical path, the optical path is provided with a power switch 1, an LED point light source 2, a diabet lens ...
Embodiment 2
[0106] Example 2: The present invention provides a system and method for measuring a temperature and volume fraction of a carbon cigarette particle temperature based on an LED light source. This embodiment provides a system and method for measuring the temperature and volume fraction of the carbon cigarette particles based on the LED surface light source. The system is a measurement system with optical path two, is a simplified system for measuring the temperature and volume fraction of carbon cigarette particles; figure 2Indicated. The power switch 1 is connected to the LED surface light source 10, and a neutral density filter 6, a prism camera 8, and a computer 9 are provided in the back sequence of the LED surface light source. When the LED surface light source, neutral density filter, the center height of the prism camera lens is in the same height, which is the height of the flame center on the burner; the installation distance of the LED surface light and the neutral density...
