Device for detecting carbon content of fly ash

Abstract

The invention discloses a device for detecting the carbon content of fly ash, and relates to the technical field of detection of carbon content of fly ash. The device comprises a storage container; anignition mechanism is arranged in the storage container, and comprises a plurality of spherical ignition shells and a plurality of connecting cylinders; the spherical ignition shells are sequentiallynested with one another; the connecting cylinders penetrate from the spherical ignition shell on the outmost layer to the interiors of the spherical ignition shell on the innermost layer; vent pipesare led out from the end parts of the connecting cylinders and then expand upwards vertically; the upper ends of the vent pipes are communicated with the lower ends of vents; the vents are channels ofwhich the internal diameters are gradually expanded from bottom to top; and the bottom end of the spherical ignition shell on the outmost layer is connected to the bottom of the storage container through a supporting pillar. The invention aims to overcome the defect that in the conventional technical scheme that the carbon content of fly ash is measured on the basis of an ignition carbon loss method, the measurement accuracy is lower, and provides the device for detecting the carbon content of the fly ash. The measurement accuracy of the carbon content of the fly ash is improved.

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 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 suitable fo...
