Abstract

The invention discloses a multi-method fused online measurement system for the carbon content of flowing fly ash, which is characterized by comprising a central control terminal, a shell, a laser detector and an infrared detector, wherein the laser detector and the infrared detector are arranged in the shell, a fly ash channel is formed in the middle of the shell, the laser detector is used for detecting laser data of carbon ash in the fly ash channel, the infrared detector is used for detecting light transmission data of carbon ash in the fly ash channel, the central control terminal is used for being in communication connection with the laser detector and the infrared detector, the central control terminal is used for receiving the laser data detected by the laser detector and the light transmission data detected by the infrared detector and calculating a carbon content numerical value, the central control terminal further comprises a holographic recording module and a holographic reconstruction module, the holographic recording module is used for recording interference and diffraction of laser rays and infrared rays to record interference images, and the holographic reconstruction module is used for reconstructing the interference images to obtain image information of an original object. The monitoring system has the functions of quick measurement, accurate result, low cost and convenience in use.

Description

Technical field [0001] The present invention relates to a measuring system, and more particularly, it involves a multi-method fusion flow fly-containing carbon content online measurement system. Background technique [0002] Optimization control of boiler combustion efficiency has always been the core concern of coal-fired power plants. The amount of fly ash contains one of the important parameters characterized by the boiler combustion efficiency, and reflects the operation management level of the coal-fired power plant to a certain extent. In the past, the method of detecting flying ash carbon content has time delay, susceptible to other elements, unhappy accuracy, with large improvement space. [0003] At present, fly ash carbon content has a microwave method, burning weight loss, fluidized bed CO2 method, laser-induced breakdown spectroscopy, radiation method and other technical methods. Among them, the burning loss is the common method of coal-fired power plants, and the tra...
