Device for detecting carbon content of fly ash in coal-fired power generation boiler

Abstract

The invention discloses a device for detecting the carbon content of fly ash in a coal-fired power generation boiler and belongs to the technical field of detection of carbon content of fly ash. The device for detecting the carbon content of the fly ash in the coal-fired power generation boiler comprises a drying furnace, a burning furnace, a burning container and a lifting rotary tray, wherein one end of the drying furnace is communicated with an inert gas supply mechanism through a pipeline, and the other end of the drying furnace is communicated with a vacuum pump I through a pipeline; oneend of the burning furnace is communicated with an oxygen supply mechanism through a pipeline, the other end of the burning furnace is communicated with one end of a sealed container through a pipeline, and the other end of the sealed container is communicated with a vacuum pump II through a pipeline; the lifting rotary tray is used for transporting the burning container. The invention aims to overcome the defects of low measurement accuracy and reliability of the conventional technology for detecting the carbon content of the fly ash in the coal-fired power generation boiler, provides the device for detecting the carbon content of the fly ash in the coal-fired power generation boiler, and improves the accuracy and the reliability of measurement on the carbon content of the fly ash.

Description

technical field [0001] The invention relates to the technical field of detection of carbon content in fly ash, and more specifically relates to a detection device for carbon content of fly ash of a coal-fired power generation boiler. Background technique [0002] The carbon content of fly ash is an important operating index and economic index of coal-fired power generation boilers. According to the detected carbon content of fly ash, the air-to-coal ratio can be adjusted in time to improve the combustion efficiency of coal-fired power generation boilers, thereby reducing coal consumption and improving boiler efficiency. Economical to run. At present, the physical and chemical properties of carbon, such as the flammability and high dielectric constant of carbon, are mainly used to detect the carbon content of fly ash. The detection methods of carbon content in fly ash can be mainly divided into microwave method, optical emission method, infrared detection method, thermogravi...
