Research of Plasma Spectrum Diagnosis and Quantitative Analysis for Coal Powder Flow
Laser-induced breakdown plasma spectroscopy of coal powder flow has a series of advan-tages such as simple system,simple sample preparation,fast multi-element analysis,and representa-tive detection.Thus,it has wide application prospect in the field of online analysis of coal property.This paper briefly introduces the basic principles of laser-induced breakdown spectroscopy and the measurement device for coal powder flow,and then elaborates the influencing factors and improved methods for the measurement of coal powder flow.Subsequently,it introduced the current situation of quantitative analysis of coal property and the rapid coal analyzer based on plasma spectroscopy of coal powder flow.Finally,the development trend of the plasma spectroscopy of coal powder flow is prospected.This work provides a reference for the development and application of this technique.
