Space temperature, volatile content, moisture content of the coal used, and collector pipe pressure? ? ? ? The space temperature is currently around 800, with little change, but as the volatiles in the coal increase, it would logically be expected that the tar yield should increase. However, the tar yield has actually decreased. Why is that?
First is the tar yield associated with the coal; some coals produce less tar. Second is process adjustment.
The volatiles of the coaling coal, turnaround time, coal loading amount, temperature, and gas collector pressure all affect the tar yield.
Recently, the production of tar has also experienced significant fluctuations; it’s beneficial to study this. :)
A viscous black or dark brown liquid with a pungent odor, produced during the carbonization of coal. Abbreviated as tar. The composition and yield of the volatiles obtained through primary thermal analysis of coal are primarily influenced by the properties of the coal. The higher the volatiles content in the raw coal, the lower its softening temperature, and the wider the temperature range within which gelatinous substances form; as a result, the yield of coal tar increases, and the proportion of hydrogen in the elemental composition of coal tar also increases
Additional note: The above views are presented from a macroscopic perspective; however, optimization and stability in the clarification and separation of ammonia water, tar, and slag are also necessary.
That makes sense. With certain fluctuations in coal quality, it is essential to strengthen the control of oil content in ammonia water, raw gas, and tar residue; as a result, the tar recovery rate will also increase accordingly.
