What are the factors that affect coal tar production in rammed coke ovens?

The most direct one is the proportion of bituminous coal and coking coal to be added. When these two types of coal are used in large quantities, the volatile matter content increases, which in turn results in more gas production. As a consequence, there is also a greater amount of by-products such as tar, benzene, toluene, ammonia, and so on. . However, too much coke leads to a decrease in strength.
It is mainly related to the volatility of the coal fed into the furnace and the temperature in the roof space of the coke oven
1. In terms of the formula, the main change is in the coal mix; there is a clear increase in gas-rich and fertilizer-coal, as well as an increase in tar content. 2 The process of tar production mainly relies on temperature control. 3. The recovery of tar relies on reducing the temperature (by spraying ammonia water and using a pre-cooler), which causes the tar and ammonia water to combine ; Secondly, electrostatic tar collectors are used to remove tar dust. When these two substances are drawn to the \"large vessel,\" ammonia and tar are separated
I’m also troubled by the low tar production; I’ll keep paying attention
In addition to the reasons mentioned above, the low tar yield when producing coke is also related to the height of the coal cake; if the height of the coal cake is not sufficient, the tar yield will decrease as well
