4 Coulomb Sulfur Meter

4.1 Overview The working principle of the coulomb sulfur meter is as follows. the coal sample is burned and decomposed in the air flow under the action of a catalyst, and the sulfur in the coal generates sulfur oxides, where Sulfur dioxide is absorbed by the potassium iodide solution, titrated with the iodine produced by the electrolysis of the potassium iodide solution, and calculated based on the electricity consumed by the electrolysis. Total sulfur content. Coulomb sulfur meter mainly consists of a tubular high-temperature furnace, electrolytic cell and electromagnetic stirrer, air supply and purification device, Coulomb integrator, It is composed of sample delivery program controller and other parts. Figure 1 is a schematic diagram of the basic structure of the coulomb sulfur meter. ......
