Description

Technical Field

[0001] The utility model relates to the technical field of sulfur determination instruments, in particular to a sulfur determination instrument used for detecting sulfur components in coal. Background Art

[0002] The total sulfur content in coal is one of the important indicators for evaluating coal quality. It is also one of the main components of air pollution. The sulfur analyzer is an instrument used to detect the sulfur content in coal or other minerals. The sulfur analyzer consists of an air purification device, a controller, a combustion furnace, an electrolytic cell and an agitator.

[0003] The current method of using a sulfur analyzer is to burn the mineral in a combustion furnace and then transport the generated airflow to the instrument for detection. At present, the combustion furnace in most sulfur analyzers is set inside the instrument. However, this makes it inconvenient to clean the inner chamber of the combustion furnace, which makes it easy for impurities generated by the combustion of the mineral to accumulate on its surface, thereby affecting the heat conduction of the combustion furnace, which is not conducive to the rapid combustion of the mineral, and also increases the energy required to burn the mineral, resulting in energy waste. Therefore, a sulfur analyzer for detecting the sulfur component in coal is proposed. Utility Model Content
