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...
