Embodiment Construction

[0013] Give an embodiment below in conjunction with accompanying drawing: as figure 1 , as shown in Figure 2, the ash discharge seat 1 of the fly ash sampling ash discharge device is cubic, and it is fixed on the support 2 below by the ash discharge seat nut. The ash discharge seat 1 has through holes 3, 4, 5 up and down, left and right, front and back, and the upper hole 3 is connected to the quartz detection tube 6, and the quartz detection tube 6 is equipped with a casing, and is locked by a lock nut. The lower hole 3 leads to a blowback nozzle 7 and a compressed air inlet 8 . Left and right, front and back two groups of through holes 4,5 are installed in a criss-cross pattern on the upper and lower floors, and all communicate with the upper and lower through holes 3 . The left and right through holes 4 of the upper layer are ash discharge passages, equipped with ash discharge nozzles 9 and ash discharge acceleration tubes 10, and the ash discharge acceleration tubes 10 ar...

Description

technical field [0001] The invention relates to an on-line monitoring device for carbon content in boiler fly ash, in particular to a fly ash sampling ash discharger in the device. Background technique [0002] The carbon content in fly ash of coal-fired boilers in thermal power plants is an important index to measure boiler operation and combustion efficiency. Reasonably controlling the carbon content index of boiler fly ash within a certain range is conducive to improving the economy of boiler and generating set operation, reducing the cost of power generation, and is also conducive to expanding the comprehensive utilization of fly ash. In order to adapt to the development of the power industry and the requirements of operating economy, real-time sampling, real-time testing, and online monitoring of carbon content in fly ash have become a development trend. The fly ash sampling ash discharger is an essential part of the boiler fly ash carbon content online monitoring devi...
