Effect of density change after gas switching for pulverized coal gasification and pulverized coal transport
Thread Content
After the conveying gas was switched from nitrogen to carbon dioxide, the ray densitometer showed an increase in density – what is the principle behind this? Is it the high molecular weight and high density of carbon dioxide that affect the densitometer, or are it changes in other properties of the gas that lead to an increase in the solid coal particles in the coal powder pipeline?
By how much has it risen? Are there specific figures?
High density; gas switching requires recalibration
The Russian Ikofis Na-22 radioactive densitometer is an ideal alternative to hazardous gamma radiation sources such as cobalt 60 and cesium 137. With its notable advantages including low radiation levels, high precision, and the absence of approval procedures, it greatly simplifies the use of densitometers in the mining industry. It poses no harm to operators or the environment, while also reducing costs associated with use and maintenance. Thus, it contributes to improving the technical standards of China’s automation sector!
