T/CBWA 0028-2024 Laser-induced breakdown spectroscopy (LIBS) for rapid inspection of coal performance indicators

Scope

Scope: This document specifies a method for rapid testing of coal performance indicators using laser-induced breakdown spectroscopy (LIBS). This document is applicable to the rapid detection of carbon, hydrogen, nitrogen, total sulfur content, as well as ash, volatile matter, and calorific value in coal. Main technical content: This standard is based on the research results of scientific projects such as "Online Monitoring Technology Research and System Development for Carbon Emissions" and "Platform Construction and Related Technology Research for Carbon Emission Verification and Monitoring Services". At present, these projects have achieved preliminary results. A laser-induced breakdown spectroscopy (LIBS) coal quality rapid analyzer has been developed, and a pilot application has been established in a coal-fired power generation enterprise in Guangdong Province, which has been in operation for over a year and demonstrated high feasibility. This standard consists of twelve chapters, including the following: (1) Scope: To facilitate the implementation of the standard, this standard specifies a method for rapid testing of coal performance indicators using LIBS, applicable to the rapid detection of carbon, hydrogen, nitrogen, total sulfur content, as well as ash, volatile matter, and calorific value in coal. (2) Normative references: This section lists the laws, regulations, standards, and national safety technical specifications referenced during the development of this standard. (3) Terms and definitions: This section lists relevant terms and definitions in this standard, including laser-induced breakdown spectroscopy, laser-induced breakdown spectroscopy coal quality rapid analyzer, standard coal samples, calibration models, calibration sample sets, verification sample sets, wavelength calibration, repeatability, accuracy, etc. (4) Principle: This section outlines the principle of using LIBS to achieve rapid testing of coal performance indicators.
