What are the factors that affect the yield of coal chemical tar?
Thread Content
Recently, the tar yield from the company’s 5.5m ramming coke ovens has decreased significantly; the tar appears to be thicker. I’m not sure what could be causing this issue. I hope those with experience can share their insights. I also want to know whether the bulk density of the coal blend has an impact on tar yield?
The effectiveness of tar-ammonia separation and the control of furnace temperature directly affect the yield of tar. The temperature and pressure of the ammonia solution directly affect the efficiency of ammonia spraying. The control of the furnace temperature, especially that of the upper part, has an impact on the ease of ammonia spraying, as well as on the quality and yield of the product tar and the quality of the gas produced. In addition, the quality of the raw coal and other process parameters (such as the length of coking time) also exert a influence on these aspects. Specifically, what your situation is will depend on data analysis.
Both the volatile matter content of the coal and the temperature in the furnace top space have a significant impact
