Description
Technical Field
[0001] The utility model relates to the field of environmental monitoring, in particular to a chlorine content testing device for a coal-fired power plant. Background Art
[0002] The basic production process of a coal-fired power plant is to use combustible materials (such as coal) as fuel, heat water to generate steam through combustion, and convert the chemical energy of the fuel into thermal energy. Subsequently, the steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. Finally, the turbine drives the generator to rotate, converting the mechanical energy into electrical energy. This process is the core working principle of a thermal power plant. As the main force of current electricity supply, coal-fired power generation still has an irreplaceable position in terms of stability and reliability. With the development of science and technology, coal-fired power generation has transformed from a traditional industry into a high-efficiency, ultra-low-emission modern coal-fired power plant.
[0003] In coal-fired power plants, the combustion process of coal produces various substances, among which the content of chlorine has a significant impact on equipment corrosion, environmental pollution, etc. Accurately measuring the chlorine content in coal is of great significance for optimizing combustion processes, controlling pollutant emissions, and ensuring the safe and stable operation of power plant equipment. However, existing chlorine content testing methods and devices have some shortcomings, such as complex testing processes, long time consumption, and low accuracy, which cannot meet the needs of coal-fired power plants for rapid and accurate testing. Therefore, we propose a chlorine content testing device for coal-fired power plants to solve the above problems. Utility Model Content
