Problems solved by technology

[0008] The problem with these methods is that the display of the combustion background cannot be well realized (such as the water wall of the furnace, the ash deposit and slagging of the burner, the distribution of pulverized coal at the outlet of the burner, etc.), and the flame should be selected according to the measureme

Embodiment Construction

[0025] A prism three-splitting system comprising:

[0026] ——Non-polarizing beam-splitting semi-transparent beam splitter, two non-polarizing beam-splitting semi-transparent beam splitters can split an incident beam into three beams; ——Total reflection prism, seven total reflection prisms are in the optical path Arranged according to requirements, through the adjustment of the position of the total reflection prism, the optical path of the two beams of light filtered by the filter can be equal; - the optical filter, the optical filter can be placed in the optical path to obtain the light beam of the required wavelength.

[0027] The light splitting process of the present invention is: the light beam emitted by the target is divided into three beams after passing through two semi-transparent and semi-reflective beam splitters, and the three beams are arranged in two layers; After reflecting the prism, it is projected onto the imaging target surface according to the required dir...

Abstract

The invention relates to a prism tri-optical splitting system that includes semi-passing semi-reflecting light beam splitter of dis-polarization, fully reflecting prism and filter. The splitting system could split a beam to three beams that one beam is visible beam in full wave length range and the other two beams are narrow band beams having different wave length and same optical path. The splitting system could combine with light guiding device and CCD camera to realize visible measuring to flame temperature and synchronization display of burning area background. The invention could be also used to capture image process of same object of fully synchronization and taking further research.

Description

technical field [0001] The invention relates to a light splitting system, in particular to a three-way light splitting system composed of a semi-transparent and half-reflective beam splitter, a total reflection prism and an optical filter. Background technique [0002] The basic requirement of coal / oil combustion is to establish and maintain a stable combustion flame. Unstable combustion will not only reduce the thermal efficiency of the boiler, generate pollutants and noise, but also cause fire extinguishing in the furnace in extreme cases. Improper handling will induce deflagration in the furnace and cause accidents. Therefore, it is necessary to equip the furnace with a fully functional and reliable furnace flame monitoring system. At present, the flame monitoring equipment installed on boilers in China can only monitor the flame on and off, and cannot quantitatively measure the space and time parameters of the combustion condition. Even if some of them can measure the t...
