Boiler fly ash carbon content detection device

Abstract

The invention discloses a device for detecting unburned carbon in flue dust of a boiler, and relates to the technical field of detection of the unburned carbon in flue dust. The device disclosed by the invention comprises a storage container, a burning mechanism is arranged in the storage container, the burning mechanism comprises: a plurality of burning spherical shells which are sequentially nested with each other, wherein a plurality of through holes are respectively formed in all burning spherical shells in the burning spherical shell on the outermost layer; and a plurality of connecting cylinders, wherein the connecting cylinders are inserted from the burning spherical shell on the outermost layer into the burning spherical shell on the innermost layer, and the connecting cylinders are respectively fixed on each layer of burning spherical shells; wherein a connecting cylinder that vertically penetrates through all burning spherical shells from top to bottom is provided with a plurality of through holes along the entire length direction. The device disclosed by the invention aims at overcoming the shortcomings of worse measurement accuracy of the existing technical scheme of measuring the unburned carbon in flue dust based on a burning carbon loss method, and providing the device for detecting the unburned carbon in flue dust of the boiler to improve the measurement accuracy of the unburned carbon in flue dust.

Description

technical field [0001] The invention relates to the technical field of detection of carbon content in fly ash, in particular to a detection device for carbon content of boiler fly ash. Background technique [0002] The carbon content of boiler fly ash is an important index to evaluate the operating economy of the unit. On-line and real-time measurement of carbon content in boiler fly ash is conducive to timely adjustment and optimization of combustion conditions, so as to achieve the purpose of reducing coal consumption and improving unit economy. [0003] Potential utilization of boiler fly ash in the areas of adsorbents and building materials could also improve power plant economics. The carbon content of fly ash is an important indicator to determine its application field. Fly ash with high carbon content has a large specific surface area and can be used as an efficient adsorbent; however, when added to cement, it will cause the cement to crack easily, so it is not suit...
