Problems solved by technology

The traditional chemical analysis method needs to first make coal ash sample and then titrate it with chemical solution or use spectrophotometry to measure the sample solution. This method has cumbersome steps, heavy workload, too slow speed, and many opportunities for human errors. As a result, the accuracy of the measurement results is poor, and it is not suitable for the on-line analysis of the slagging trend of the coal before it is put into the furnace; the atomic absorption spectrophotometry is combined with the traditional chemical method in operation to analyze the coal ash composition; the same ICP- The AES method and the X-fluorescence method need to make ash samples from coal, and then make samples from acid-dissolved ash samples for detection. These methods are time-consuming due to tedious manual chemical analysis such as sample preparation, and are not easy to use. It is suitable for the analysis of slagging trend of coal quality before it is put into the furnace

Description

technical field [0001] The invention relates to the technical field of laser diagnosis and measurement, more specifically, relates to a [0002] A rapid monitoring device for coal slagging tendency of equipment entering the furnace. Background technique [0003] For a long time, slagging in the furnace has been one of the main factors that endanger the safety and economic operation of coal-fired equipment. With the further increase of the capacity of coal-fired equipment, this problem becomes more prominent. Therefore, it is of great significance to accurately predict the slagging tendency of the furnace and take corresponding measures to prevent serious slagging and optimize operation. There are more than 30 methods for evaluating the potential slagging tendency of coal at home and abroad, which can be divided into the following categories: ①Evaluate according to the ash melting point temperature of coal; ②Evaluate according to the viscosity-temperature characteristics of...
